Light driver

Universal 230 VAC light driver

Model number: LUD12-IQ
Connects to: LD-P4-IQ
Mounting: DIN rail, 1M, 18 mm
Dimensions: 18 × 63 × 87 mm


  • Dimming all 230 VAC dimmable lights


  • Automatic load detection
  • Electronic overload protection
  • Over-temperature shutdown

General description

Activation takes place from the LD-P4-IQ. The output voltage is adjusted from 0-100% depending on the LD-P4-IQ command. The activation terminals X1/X2 in the LUD12 are isolated from the mains voltage by an optocoupler. Automatic load detection, electronic overload protection and over-temperature shutdown are active and independent from activation.
