28000667 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.

28000667 Installation / wiring

DALI & DSI wiring of the 28000667

switchDIM wiring of the 28000667

28000667 Wiring type and cross section

For wiring use stranded wire with ferrules or solid wire from 0.2–1.5 mm². Strip 8.5–9.5 mm of insulation from the cables to ensure perfect operation of the push-wire terminals.
Use one wire for each terminal connector only. Use each strain relief channel for one cable only.

28000667 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines to achieve good EMC performance.
• The max. secondary cable (LED module) length is 2 m (4 m circuit).
• For good EMC performance, keep the LED wiring as short as possible.

• To comply with the EMC regulations run the secondary wires (LED module) in parallel.
• 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.
• Through wiring of mains is for connecting additional LED driver only.

Max. permanent current of 16 A may not be exceeded.
• To avoid damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).

Hot plug-in

Hot plug-in is not supported due to residual output voltage of > 0 V. 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, ready2mains).

Earth connection

The earth connection is conducted as protection earth (PE). The LED driver can be earthed via earth terminal. 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)
• LED glowing at standby
• 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 thereby representing a high capacity against earth.

28000667 Electrical values

Make sure that the LED driver is operated within the given window under all operating conditions. Special attention needs to be paid at dimming and DC emergency operation as the forward voltage of the connected LED modules varies with the dimming level, due to the implemented amplitude dimming technology.

Coming below the specified minimum output voltage of the LED driver may cause the device to shut-down. See chapter “6.11 Light level in DC operation” for more information.

28000667 Dimming

Dimming range 1 % to 100 %
Digital control with:
• DSI signal: 8 bit Manchester Code
Speed 1 % to 100 % in 1.4 s
• DALI signal: 16 bit Manchester Code
Speed 1 % to 100 % in 0.2 s
Programmable parameter:
Minimum dimming level
Maximum dimming level
Default minimum = 1 %
Programmable range 1 % ≤ MIN ≤ 100 %
Default maximum = 100 %
Programmable range 100 % ≥ MAX ≥ 1 %
Dimming curve is adapted to the eye sensitiveness.
Dimming is realized by amplitude dimming.

28000667 Interfaces / communication

Control input (DA/N, DA/L) Digital DALI signal or switchDIM can be wired on the same terminals (DA/N and DA/L). The control input is non-polar for digital control signals (DALI, DSI).
The control signal is not SELV. Control cable has to be installed in accordance to the requirements of low voltage installations. Different functions depending on each module.

Control input ready2mains (L, N)

The digital ready2mains protocol is modulated onto the mains signal which is wired to the mains terminal (L and N).

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.

switchDIM 2

Version 2 has now the possibility to define different fade times used for short button press events. So the fade time to set memory level (if wake-up from standby) as well as the fade time to switch off can now be configured.

28000667 Functions

Function: adjustable current

The output current of the LED driver can be adjusted in a certain range. For adjustment there are three options available.

Option 1: DALI

Adjustment is done by masterCONFIGURATOR (see masterCONFIGURATOR documentation).

Option 2: I-SELECT 2

By inserting a suitable resistor into the I-SELECT 2 interface, the current value can be adjusted. The relationship between output current and resistor value can be found in the chapter “Accessories I-SELECT 2 Plugs”.

Please note that the resistor values for I-SELECT 2 are not compatible with I-SELECT (generation 1). Installation of an incorrect resistor may cause irreparable damage to the LED module(s).

Resistors for the main output current values can be ordered from Tridonic (see accessories).

Option 3: ready2mains

Adjustment is done by the ready2mains programmer and the corresponding configuration software (see ready2mains documentation).

The priority for current adjustment methods is DALI (highest priority), I-SELECT 2, ready2mains (lowest priority).

ready2mains – configuration

The ready2mains interface can be used to configure the main parameters of LED drivers via the mains wiring, such as LED output current, CLO and DC level. These parameters can be adjusted either via ready2mains-capable configuration software or directly via the ready2mains programmer (output current only).

ready2mains – dimming

ready2mains allows for mains-based group dimming, controlled via the ready2mains protocol and appropriate dimming interfaces. For details on the operation of ready2mains and its components see the relevant technical information.

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, ready2mains).

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.

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, ready2mains).

Overtemperature protection for the 28000667

The LED driver is protected against temporary thermal overheating. If the temperature limit is exceeded the output current of the LED module(s) is reduced. The temperature protection is activated above tc max. The activation temperature differs depending on the LED load. On DC operation this function is deactivated to fulfill emergency requirements.

corridorFUNCTION

The corridorFUNCTION can be programmed in two different ways. To program the corridorFUNCTION by means of software a DALI-USB interface is needed in combination with a DALI PS. The software can be the masterCONFIGURATOR.

To activate the corridorFUNCTION without using software a voltage of 230V has to be applied for five minutes at the switchDIM connection. The unit will then switch automatically to the corridorFUNCTION.

Note:
If the corridorFUNCTION is wrongly activated in a switchDIM system (for example a switch is used instead of pushbutton), there is the option of installing a pushbutton and deactivating the corridorFUNCTION mode by five short pushes of the button within three seconds.

switchDIM and corridorFUNCTION are very simple tools for controlling gears with conventional pushbuttons or motion sensors. To ensure correct operation a sinusoidal mains voltage with a frequency of 50 Hz or 60 Hz is required at the control input.

Special attention must be paid to achieving clear zero crossings. Serious mains faults may impair the operation of switchDIM and corridorFUNCTION.

Constant light output (CLO)

The luminous flux of a LED decreases constantly over the lifetime. The CLO function ensures that the emitted luminous flux remains stable. For that purpose the LED current will increase continuously over the LED lifetime. In masterCONFIGURATOR it is possible to select a start value (in percent) and an expected lifetime. The LED driver adjusts the current afterwards automatically.

Power-up/-down fading

The power-up/-down function offers the opportunity to modify the on-/off behavior. The time for fading on or off can be adjusted in a range of 0.2 to 16 seconds. According to this value, the device dims either from 0 % up to the power-on level or from the current set dim level down to 0 %.

This feature applies while operating via switchDIM, ready2mains and when switching the mains voltage on or off. By factory default no fading time is set (= 0 seconds).

Light level in DC operation

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 % (EOFi = 0.13).
Programming by DALI or ready2mains.

In DC operation dimming mode can be activated.

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) is for:
AC: 22 mA (at 230 V, 50 Hz)
DC: 7 – 10 mA (at 275 – 186 V, 0 Hz)

Intelligent Voltage Guard

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.

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.

28000667 Software / programming

With appropriate software and an interface different functions can be activated and various parameters can be configured in the LED driver. To do so, a DALI-USB or ready2mains programmer and the software (masterCONFIGURATOR) are required.

masterCONFIGURATOR

From version 2.8: For programming functions (CLO, I-SELECT 2, power-up fading, corridorFUNCTION) and device settings (fade time, ePowerOnLevel, DC level, etc.). For further information see masterCONFIGURATOR manual.

deviceCONFIGURATOR

PC (windows) based software application to transfer parameters into our drivers. Workflow optimised for the use in OEM production line. For further information see deviceCONFIGURATOR manual.

28000667 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.

Conditions of use and storage of the 28000667

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 controlgear, 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 for the 28000667

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

Constant Current DALI LED drivers are advanced power supplies that regulate a fixed, consistent, and adjustable output current (e.g.350mA-700mA) for LEDs, while supporting intelligent digital dimming. They are ideal for commercial, architectural, and high-efficiency lighting applications using series-wired fixtures.
