MS SERIES

The MS Series is a family of solid-state frequency converters with models from 62.5 to 625 kVA, standard 47 to 500 Hz (optional to 1,000Hz) with a unique master/slave configuration, which allows up to ten 62.5 kVA mainframes to be paralleled in the field. MS Series units are available with Battery Support Systems (UMS Option), providing uninterruptible power source capability. The MS Series is designed to maximize performance, versatility and virtually eliminate downtime
