HV controller


The High Voltage is a controller capable of operating with a voltage up to 780V and suitable for AC Induction, BLDS and PMAC motors, in the range from 15 to 30kW continuous power, for traction, pump, and auxiliary functions of electric/hybrid vehicles. Thanks to this characteristic it can operate both with battery packs which are common in electric/hybrid markets (lithium types) and with an high voltage DC-link stabilized by a generator.
