The Servolink 3 kVA CVT (Constant Voltage Transformer) is the largest model in our CVT range, built in a heavy-duty cabinet on castor wheels for easy movement. It takes a single phase input anywhere from 160 V to 260 V and delivers a steady 230 V AC output within ±1%, using a ferro-resonant transformer with no relays, motors or moving parts. It comes with output terminals for direct connection to the load and a cooling fan for continuous duty.

Typical applications: CNC machines, hospital and lab equipment, industrial control panels and telecom equipment.
