Application
Galvanic isolation and circuit separation
Three-phase 400 V → 400 V for IT networks. This family is designed for galvanic isolation and circuit separation in a three-phase configuration.
Electrical configuration: input 400 V, output 400 V, range 1 a 500 kVA. Final selection should consider actual installation and protection conditions.
