Low Voltage Controllers


The Gen4-series represent the absolute highly reliable and robust design concept for compact and reliable AC Controllers. They feature one of the smallest footprint in the industry for their power capability. The controllers’ high efficiency makes it possible to integrate them into very tight spaces without sacrificing performance. The optimized design offers the lowest possible cost while maintaining superior reliability in the most demanding applications.

The Gen4 LV series cover the nominal voltage range 16.8V to 132V DC, and power levels up to 50kW.
