2-gang DRA universal dimming actuator with integrated bus coupler for switching and dimming various electrical loads. The universal dimming actuator automatically recognises the type of supplied load (inductive, ohmic or capacitive) after the first installation and after it
has been disconnected from the power supply system and sets the most suitable dimming method according to the leading or trailing edge principle. Inductive (e.g. conventional transformers) and capacitive (e.g. Gira Tronic transformers) loads may not be connected to the same output terminal. However, simultaneous operation, e.g. of inductive loads on channel 1 and capacitive loads on channel 2 is possible. The total connected load is 600 W/VA with a maximum single-channel load of 400 W/VA. Installation on DIN cap rail. Multi-phase connection. Integrated shortcircuit protection and automatic restarting after fault elimination and excess-temperature protection (separate for each channel). Power expansion via power boosts.
