Dimming actuator Connecting lamp load Figure 4: Dimming actuator – Connection example Do not exceed permissible total load including transformer power dissipation. Operate inductive transformers with at least 85% nominal load. Mixed loads with inductive transformers: ohmic load max. 50%. HV-LED lamps and compact fluorescent lamps: Only connect lamps of one manufacturer and of the same type on the same output.

Dimming actuator Choose power boosters that are suitable for the dimmer and load. Program the operation with Universal power extensions in the device or – with devices up to version V01 – set the maximum brightness to 90 %. For more information please see instructions of the re- spective power pack.
