Functions and Features

Selection of PWM output frequency by ETS, from 250 Hz to 6 kHz

Parallel connection of outputs possible to increase output power

Fade on/off time, minimum and maximum brightness level, linear or logarithmic dimming curve settable via ETS

Configuration of behaviour after power reset, bus ON/OFF, unloading via ETS

Channels can be set by ETS as independent, parallel or with copy function from another channel

Blocking function, forced operation, staircase light, scenes, night, counter and logic functions for each channel, settable from ETS

Manual control with membrane buttons for local ON/OFF testing of channels 1-2-3-4: in manual mode, short press of a channel button activates/deactivates the load, pressing for at least 2 seconds causes the load to flash every 1 s approx.

Relay contact for switching off the AC/DC power supply when 12/24/48 Vdc outputs are switched off, or alternatively as relay for auxiliary output

Auxiliary output function via relay with status indication via KNX

Degree of protection: IP00 (IP20 in junction box or switchboard)

Power supply and load wiring: 0.2 to 4.0 mm2 (24 to 11 AWG) for single cable / 0.2 to 6 mm2 (24 to 9 AWG) for stranded cable

Configuration and Commissioning

A detailed description of the parameters can be found in the device's application manual. ETS5 or later versions are required for configuration and commissioning. Application programme for ETS: APEKGDXTPXLVM##.knxprod (## = version).
