====== Light dimmer ======

**Universal 230 VAC light driver**

</WRAP>

===== Applications =====

* Dimming all 230 VAC dimmable lights

</WRAP>

===== Features =====

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

===== General description =====

Activation takes place from the [[en:hiq_home:hardware:ld-p4-iq|LD-P4-IQ]]. The output voltage is adjusted from 0-100% depending on the [[en:hiq_home:hardware:ld-p4-iq|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.
