Lumento C4. 4-channel constant current PWM dimmer for DC LED loads

Lumento C4. 4-channel constant current PWM dimmer for DC LED loads

Product code: ZDIRGBCC4
LED dimmer with 4 channels (RGBW or single channels) oriented to LED technology with constant current regulation. The dimming channels can be configured as 4 independent channels, 1 RGBW channel or 1 RGB channel + 1 individual channel. It has a manual test button to check the channels functioning. Maximum current selection with parameter and manual selector: 220, 300, 350, 500, 550, 630, 700 or 750, 900 and 1000 mA.

Technical Details


General System Specifications

  • KNX Power Supply: 29VDC
  • KNX Current Consumption: 8mA @ 29VDC
  • Operating temperature: 0 ¡C to 45 ¡C
  • Assembly: Independent control assembly device. Connect LUMENTO as near as possible to both, the load to dimmer and the external power supply.
  • Bus power failure response: Data saving
  • Response when restarting bus: Data recovery
  • Operation Indicator: Programming LED: programming mode (red lighting), safe mode (red blinking). Test LED: in test mode, red, test channel 1 (R); green, test channel 2 (G); blue, test channel 3 (B). Reverse polarity of external power supply is indicated by the test LED in orange light. If there is not an external power supply connected it blinks in orange. If the currents selected by parameter and by selector switch don't match it blinks in white. Overheating protection: the test LED lights in red (continuous level 1 of protection, blinking with level 2 of protection).
