The LED control gear 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.
28004430 Installation / wiring
28004430 Circuit diagram
28004430 Wiring type and cross section
For wiring use stranded wire with ferrules or solid wire from 0.2 – 1.5 mm².
For perfect function of the push-wire terminals (WAGO 250) the strip length should be 8.5 – 9.5 mm.
Use one wire for each terminal connector only.
LED module/LED driver/supply
28004430 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.
• 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 (DSI, switchDIM).
Control terminals
There is a risk of electric shock when touching these terminals in case of failure.
Fixing conditions when using as independent Driver with Clip-On
Dry, acidfree, oilfree, fatfree. It is not allowed to exceed the maximum ambient temperature (ta) stated on the device. Minimum distances stated below are recommendations and depend on the actual luminaire. Is not suitable for fixing in corner.

28004430 Software / Programming / Interfaces
28004430 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 for configuration:
• companionSUITE (deviceGENERATOR, deviceCONFIGURATOR,
deviceANALYSER, 4service NFC app)
• masterCONFIGURATOR
Interfaces for data transfer:
• NFC
• Control input DALI
Nearfield communication (NFC) & 28004430
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
With a suitable NFC antenna several devices can be programmed at the same time (NFC multiprogramming). 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

OEM GTIN
The Original Equipment Manufacturer (OEM) can set his own Global Trade
Item Number (GTIN).

Luminaire data
This function provides the asset management with accurate data about the luminaire.
DALI Part 251: Memory bank 1 extension.
DALI Part 253: Luminaire maintenance data.
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.
corridorFUNCTION & 28004430
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.
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 of the LED driver.
28004430 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.
This is a safety-relevant parameter. The setting is relevant for the dimensioning of the central battery system.
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) is for:
AC: < 27.6 mA
DC: < 3.1 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 and DSI.
28004430 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.
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).
28004430 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.
Indicates the remaining lifetime of the driver. 100 % is a new device, 0 % should be urgently replaced. Helps the advanced user to understand what is the health status of the driver.
Indicates the degree of aging based on current conditions. 0 % no aging, > 20 % driver may not survive warranty. Please check the LED driver condition. These parameters are only used to estimate the condition of the device.
deviceKEY
This function enables a password protection for device settings to prevent unauthorized access or changes.
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.
28004430 Protective features
28004430 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.
28004430 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.
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).
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. The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM).
28004430 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).
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 EN 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, EN 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 for the 28004430
Humidity: 5 % up to max. 85 %, not condensed (max. 56 days/year at 85 %)
Storage temperature: -40 °C up to max. +85 °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).
DALI constant voltage LED drivers are intelligent power supplies designed to control 12V/24V/48V LED strip lighting via the Digital Addressable Lighting Interface (DALI) protocol. They allow for precise digital dimming, individual addressability, and integration into building management systems, commonly providing PWM output for flicker-free lighting.
