28004037 Thermal details and lifetime

The LED driver is designed for a lifetime stated above under reference conditions and with a failure probability of less than 10 %.

The relation of tc to ta temperature depends also on the luminaire design.

If the measured tc temperature is approx. 5 K below tc max., ta temperature should be checked and eventually critical components (e.g. ELCAP) measured. Detailed information on request.

28004037 Installation / wiring

Circuit diagram

28004037 Wiring type and cross section

For wiring use solid wire from 0.5 – 1.5 mm².
Strip 8 – 9 mm of insulation from the cables to ensure perfect operation of terminals

28004037 Device assembly

For mounting the device washer with outer diameter of 10 mm should be used. The tightening force of the M4 screw should be 3.5 Nm.

28004037 Wiring guidelines

• The cables should be run separately from the mains connections and mains cables to ensure good EMC conditions.
• The LED wiring should be kept as short as possible to ensure good EMC.

The max. secondary cable length is 2 m (4 m circuit).
• Secondary switching is not permitted.
• The LED driver has no inverse-polarity protection on the secondary side.

Wrong polarity can damage LED modules with no inverse-polarity protection.

• Wrong wiring of the LED driver can lead to malfunction or irreparable damage.
• With mains transients of 4 kV can voltage peaks up to 4 kV occur against PE at the output of the LED driver. This has to be considered concerning the dielectric strength of the LED module (insulation against PE).
• To avoid damage of the Driver, the wiring must be protected against short

28004037 Hot plug-in

Hot plug-in is not supported due to residual output voltage of > 0 V up to mains voltage. Danger to life.

When connecting an LED load, restart the device to activate the LED output.

This can be done via mains reset or via interface (DALI, DSI, switchDIM).

28004037 Earth connection

The earth connection is conducted as protection earth (PE). The LED driver can be earthed via earth terminal or metal housing. If the LED driver will be earthed, protection earth (PE) has to be used. There is no earth connection required for the functionality of the LED driver. Earth connection is recommended to improve following behaviour:
• Electromagnetic interferences (EMI)
• Transmission of mains transients to the LED output

In general it is recommended to earth the LED driver if the LED module is mounted on earthed luminaire parts respectively heat sinks and therebyrepresenting a high capacity against earth.

Replace LED module

1. Mains off
2. Remove LED module
3. Wait for 30 seconds
4. Connect LED module again
Hot plug-in or secondary switching of LEDs is not permitted and may cause a very high current to the LEDs.

28004037 Industry application

This driver is designed for industry applications.
Due to the high performance of the driver, there may be a slightly increased noise level.
The starting sound, when switching on the driver, can possibly be heard more.
The nominal lifetime of 100,000 hours and its temperatures are designed for standard applications.

However, the driver can also withstand higher temperatures, which are shown in Table 2.1.
At high temperatures, the lifetime is reduced accordingly.

Programmable range 100 % ≥ MAX ≥ 1 %
Dimming curve is adapted to the eye sensitiveness.
Dimming is realized by amplitude dimming.
Physical minimal current is 1 % of max. current of the driver

28004037 Software / Programming / Interfaces

28004037 Software / programming

With appropriate software and interface different functions can be activated and various parameters can be configured in the LED driver.
The Driver supports the following software and interfaces:
Software / hardware for configuration:
• companionSUITE (deviceGENERATOR, deviceCONFIGURATOR,
deviceANALYSER)
• masterCONFIGURATOR
Interfaces for data transfer:
• NFC
• Control input DALI

28004037 Nearfield communication (NFC)

The NFC Interface allows wireless communication with the LED driver. This interface offers the option to write configuration and to read configuration, errors and events with the companionSUITE. A correct communication between the LED driver and the NFC antenna can only be guaranteed if the antenna is placed directly on the Driver.

Any material placed between the LED driver and the NFC antenna can cause a deterioration of the communication quality. After programming the device via NFC power up the device one time for one second till the deviceANALYSER can read out the parameters.

We recommend the use of following NFC antenna:
www.tridonic.com/nfc-readers
NFC is complied with ISO/IEC 15963 standard.
Changing parameters via NFC shall be done by qualified engineers only.

Control input DALI

The control input is non-polar for digital control signals (DALI).
The control signal is not SELV. The control cable has to be installed in
accordance to the requirements of low voltage installations.
Digital control with:
• DALI signal: 16 bit
• DSI signal: 8 bit

28004037 switchDIM

Integrated switchDIM function allows a direct connection of a pushbutton for dimming and switching.

Brief push (< 0.6 s) switches LED driver ON and OFF. The dimm level is saved at power-down and restored at power-up.

When the pushbutton is held, LED modules are dimmed. After repush the LED modules are dimmed in the opposite direction.

In installations with LED drivers with different dimming levels or opposite dimming directions (e.g. after a system extension), all LED drivers can be synchronized to 50 % dimming level by a 10 s push.

Use of pushbutton with indicator lamp is not permitted.

DALI Part 251: Memory bank 1 extension.
DALI Part 253: Luminaire maintenance data.

LED current

The LED output current must be adapted to the connected LED module.
The value is limited by the current range of the respective device.
The output current of the LED driver can be adjusted in a certain range.
For adjustment there are 2 options available.

Option 1: DALI
Adjustment is done by companionSUITE or by masterCONFIGURATOR.

Option 2: NFC
Adjustment is done by companionSUITE via NFC.

Device operating mode

A Tridonic Driver supports several control signals.
These control signals are automatically detected and the mode is adapted.
If only one special device mode is required, this mode can be selected.
“Automatic detection” is the default setting.

switchDIM

Integrated switchDIM function allows a direct connection of a pushbutton for dimming and switching.
Brief push (< 0.6 s) switches LED driver ON and OFF. The dimm level is saved at power-down and restored at power-up. When the pushbutton is held, LED modules are dimmed. After repush the LED modules are dimmed in the opposite direction.

In installations with LED drivers with different dimming levels or opposite dimming directions (e.g. after a system extension), all LED drivers can be synchronized to 50 % dimming level by a 10 s push.

Use of pushbutton with indicator lamp is not permitted.

28004037 corridorFUNCTION

With the corridorFUNCTION and a commercially available motion detector, it is easy to adapt the lighting in one area to its use.

That is, when the area is entered by a person, the lighting dims instantly to the desired brightness and is available in full strength.

After the area is left by the person, the brightness dims slowly to a smaller value or switches off completely.

The individual parameters of the desired profile, such as brightness values or delay times, can be adjusted flexibly and individually.

28004037 Enhanced Constant Light Output (eCLO)

With this function the light output of the LED module can be kept equal over the lifetime. The light output of an LED module reduces over the course of its lifetime. The Constant Light Output (eCLO) function compensates for this natural decline by constantly increasing the output current of the LED driver throughout its lifetime.

Enhanced eCLO shall be achieved by limitation of the LED current at the commissioning of the LED driver and providing a linear interpolation of the current over the time, depending on the data points given by the user.

The user has to insert up to eight pairs of data (time, level). The output curve is the result of connecting the user data points linear. Detailed description for eCLO see product manual.
The minimal CLO starting point is limited by the smallest output current ofthe LED driver.

DC operation

In emergency light systems with a central battery supply the DC recognition function uses the input voltage to detect if emergency mode is present.

The LED driver then automatically switches to DC mode and dims the light to the defined DC level.
Without DC recognition different and more complex solutions would have to be applied in order to detect emergency mode.
DC recognition is integrated in the device as standard. No additional commissioning is necessary for activation

The LED driver is designed to operate on DC voltage and pulsed DC voltage. For a reliable operation, make sure that also in DC emergency operation the LED driver is run within the specified conditions as stated in chapter “4.1 operating window”.

Light output level in DC operation: programmable 1 – 100 % (factory default = 15 %, EOFi = 0.13).

The voltage-dependent input current of Driver incl. LED module is depending on the used load.

The voltage-dependent no-load current of Driver (without or defect LED module and DALI bus power supply deactivated) is for:
AC: < 77 mA
DC: < 1.35 mA

In DC operation dimming mode can be activated. If Dimming on DC is activated the requirements of the DC recognition function are ignored.
Even if DC is detected, the LED driver continues to behave as in AC mode

• The present dimming level is retained
• An emergency light level defined for the DC recognition function (DC level) is ignored
• Control signals via DALI continue to be executed

If Dimming on DC is activated then emergency mode is not recognised.
The device no longer automatically switches to the emergency light level.

Enhanced power on level (ePOL)

The Enhanced Power On Level parameter defines the power level that is set automatically when power is restored after a power failure.

The Enhanced Power On Level can be set to a fixed value (0 – 100 %) or can recall the memory value.
The memory value is the last value the LED driver was set to before the power failure.
This value applies not only in DALI device operating mode, but also in the device operating mode switchDIM.

Energy reporting

This function complies to DiiA specification DALI Part 252 – Energy reporting. It provides the information related to energy reporting accessible through memory banks in this driver.

Several functions and values could be read out to gain access in Content management systems.

Report and values for Active power, Active Energy and many more can be read out.

Diagnostics and maintenance

This function complies to DiiA specification DALI Part 253 – Diagnostics and maintenance. It provides the information related to diagnostics and maintenance information accessible through memory banks. Several functions and values could be read out to gain access in Content management systems.
Report and values for failure behaviour, driver conditions and malfunctions trigger points can be read out.

DALI default parameters

In order for all luminaires to react the same for each operation (switching, dimming, scene recall …), these values must be set the same.
These DALI standard parameters are supported by every DALI-2 device.

Scenes and groups

Each device can be a member of up to 16 groups.
Also, 16 different scene values can be stored in each device.

fade2zero

When the Driver is switched off, fade2zero allows a smooth dimming down to almost zero.
Activate the fade2zero function when programming with companionSUITE and set a DALI fade time. fade2zero only works if the minimum dimming level of the Driver is the default value.
The device then dims to far below the limit of its working window (dimming range).
This function is deactivated by default.

Power-up fading

The power-up function offers the opportunity to modify the on behavior.
The time for fading on can be adjusted in a range of 0.2 to 16 seconds.
According to this value, the device dims from 0 % up to the power-on level.
By factory default no fading time is set (= 0 seconds).

Dimming curve

DALI:
The desired dimming behaviour is selected via two different dimming curves
(logarithmic or linear).
The default setting of the dimming behaviour is logarithmic.

Lifetime indicator

This function provides the information related to driver health and aging rates. Constant monitoring allows us to make an estimation of the health status of the device. This is an indication of the condition of the driver and a guide as to when a driver should be replaced.

28004037 Protective features

28004037 Intelligent temperature guard (ITG)

The Intelligent temperature guard (ITG) function provides effective protection against thermal overloads by slowly reducing the output if a defined internal temperature is exceeded.
The reduction of overtemperatures takes place in small steps every two minutes. As soon as the temperature drops again, the output power is gradually increased every 10 minutes.
On DC operation this function is deactivated to fulfill emergency requirements.

28004037 Intelligent Voltage Guard (IVG)

Intelligent Voltage Guard is the name of the electronic monitoring of the mains voltage. It immediately shows if the mains voltage rises above certain thresholds. Measures can then be taken quickly to prevent damage to the LED driver.
• If the mains voltage rises above approx. 280 Vrms (voltage depends on the LED driver type), the LED light starts flashing on and off.
• To avoid a damage of the LED driver the mains supply has to be switched off at this signal.

28004037 Short-circuit behaviour

In case of a short-circuit at the LED output the LED output is switched off.
After restart of the LED driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM)

28004037 No-load operation

The LED driver will not be damaged in no-load operation. The output will be deactivated and is therefore free of voltage. If a LED load is connected the device has to be restarted before the output will be activated again.

28004037 Overload protection

If the maximum load is exceeded by a defined internal limit, the LED driver turns off the LED output. After restart of the LED driver the output will be
activated again.

The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM).

Extended industry standard

The devices of the industrial series are tested with various tests. For the special industrial sector additional extended tests are carried out.
A special test method (see EN 60068-2-27 (shock – test case: 1,000 shocks in 6 directions with 30 g / 18 ms) and EN 60068-2-64 (vibration – test case: acc. to table A.1 transport / category 2)) ensures operation in extreme environmental conditions.

This robustness is also achieved by the selection of special exclusive components

Miscellaneous

Insulation and electric strength testing of luminaires

Electronic devices can be damaged by high voltage. This has to be considered during the routine testing of the luminaires in production.
According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, each luminaire should be submitted to an insulation test with 500V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal.

The insulation resistance must be at least 2MΩ. As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength with 1500V AC (or 1.414 x 1500V DC). To avoid damage to the electronic devices this test must not be conducted.

Control terminals

There is a risk of electric shock when touching these terminals in case of failure.

Conditions of use and storage
Humidity: 5 % up to max. 85 %,
not condensed
(max. 56 days/year at 85 %)
Storage temperature: -40 °C up to max. +80 °C

The devices have to be acclimatised to the specified temperature range (ta) before they can be operated.

The LED driver is declared as inbuilt LED control gear, meaning it is intended to be used within a luminaire enclosure.

If the product is used outside a luminaire, the installation must provide suitable protection for people and environment (e.g. in illuminated ceilings).

Maximum number of switching cycles

All LED driver are tested with 50,000 switching cycles.
The actually achieved number of switching cycles is significantly higher.
