Application
230 V to 400 V step-up with isolation for residential use
Three-phase step-up transformer intended for homes and residential installations with a 230 V three-phase supply that need to power equipment designed for 400 V. Unlike an autotransformer, it maintains galvanic separation between the incoming supply and the output.
The IP65 version provides a higher level of protection against dust and water, making it more suitable where the residential installation requires a more protected enclosure. Final location must comply with the intended installation and service conditions. It is suitable where electrical separation from the original supply is required in addition to voltage conversion. It is also designed for residential use with quiet operation and low energisation inrush current, reducing the risk of nuisance circuit-breaker tripping.
