Application

230 V to 400 V adaptation in residential three-phase installations

Three-phase autotransformer intended for homes and residential installations with a 230 V three-phase supply that need to power equipment or a circuit designed for 400 V. It adapts voltage without providing galvanic isolation.

The IP23 version is intended for indoor installation in a protected environment. As an autotransformer, input and output are not electrically isolated; suitability for the equipment and the home's protection scheme must be checked. It is also designed for residential use with quiet operation and low energisation inrush current, reducing the risk of nuisance circuit-breaker tripping.
