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.

28001909 Wiring

28001909 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.

28001909 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines to achieve good EMC performance.
• The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well as for I-SELECT 2.
• For good EMC performance, keep the LED wiring as short as possible.
• 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.

• In case of protection class II applications it’s recommended to separate the lamp wires of the different channels. Depending onto the luminaire construction additional actions, such as equipotential connection between driver and LED or a toroidal ferrite at the lamp wires are recommended.

• To avoid the 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).

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)
• LED glowing at stand-by
• 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.

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 “6.8 DC operation” for more information.

28001909 Software / Programming / Interfaces

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

28001909 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:
• Control input DALI

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”.

If the resistor is connected by wires a consistent base insulation must be ensured. Furthermore, a max. wire length of 2 m may not be exceeded and potential interferences have to be avoided.

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) is for:

AC: 21.8 mA (at 230 V, 50 Hz)
DC: 5 – 7 mA (at 275 – 186 V, 0 Hz)

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.

DALI Linear Multi-Channel DT8 systems are advanced LED lighting solutions designed for precise color control (Tunable White, RGB, or RGBW) within linear fixtures, using a single DALI address to control multiple channels.

These systems, commonly used for linear architectural lighting, utilize the IEC 62386-209 standard (Device Type 8) to manage colour temperature and intensity, reducing wiring complexity and addressing, and are often available in 24V or 48V DC variants.

Key Features and Capabilities

Single Address Control: Unlike DT6 (which requires one address per channel), DT8 uses a single address to control CCT, RGB, or RGBW, significantly simplifying installation.

Multi-Channel Output: Often designed with 4 or 5 channels (PWM output) to manage RGBW or RGB+Tunable White configurations, allowing for vibrant color mixing and tunable white adjustment.

7-in-1 Flexibility: Some advanced controllers (e.g., Sunricher SR-2309PRO-5C) support 7 modes: Tc, RGBWAF, XY, 2*Tc, XY+Tc, RGB+Tc, and XY+W (DT6), allowing one device to handle various lighting requirements.

Compatibility: Fully compatible with universal DALI-2 systems and masters.

Built-in Dimming & Colour Control: Many models include push-dim functionality to control brightness, color temperature, and RGB colours without a dedicated DALI signal.

High Power Options: Available for linear applications requiring significant power, such as 300W-900W (12-36V) or 720W (48V).

Flicker-Free & Deep Dimming: Supports smooth dimming down to 0.1%, ensuring high-quality, flicker-free performance.
