87500923 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.

87500923 Fixing conditions

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.

Device is not suitable for fixing in corner.

87500923 Mains supply wires

For wiring use stranded wire with ferrules or solid wire from 0.5–2.5 mm2. Strip 9–10 mm of insulation from the cables to ensure perfect operation of the push terminals. Use one wire for each terminal connector only. Use each strain relief channel for one cable only.

87500923 Secondary wires (LED module)

For wiring use stranded wire with ferrules or solid wire from 0.5–1.5 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.

87500923 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).
• 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.).

87500923 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 “6.4 Light level in DC operation” for more information.

87500923 Software / Programming / Interfaces

87500923 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
• Control input switchDIM

87500923 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
Dimming is realized by amplitude dimming.

Control Input switchDIM

A standard pushbutton (switchDIM) can be wired on the terminals (DA/N and DA/L).

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.

87500923 Functions

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 priority for current adjustment methods is NFC / DALI (highest priority).
Minimum output current is default.

corridorFUNCTION

A motion detector (corridorFUNCTION) can be wired on the terminals (DA/N and DA/L).

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 a certain brightness and is available in desired 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.

To activate the corridorFUNCTION without using software a voltage of 230V has to be applied at the DA/N and DA/L connection.

The unit will then switch automatically to the corridorFUNCTION. corridorFUNCTION is a very simple tool 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 corridorFUNCTION.

Constant Light Output (CLO)

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 (CLO) function compensates for this natural decline by constantly increasing the output current of the LED driver throughout its lifetime.

CLO 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.

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 is programmable (0; 1 – 100 %).

Default value is 100 % (EOFi = 0.95).

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: < 28 mA
DC: < 6 mA

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 either from 0 % up to the power-on level.

By factory default no fading time is set (= 0 seconds).

Constant current (CC) LED drivers are specialized power supplies that maintain a fixed, regulated current (e.g., 350mA, 700mA) while adjusting output voltage to suit the LED load. They prevent premature failure by ensuring stable brightness and preventing thermal runaway, making them ideal for high-power COB modules, LED downlights, and series-wired, high-efficiency lighting systems.
