South Africa has Africa's most developed manufacturing, mining and automotive industries. Years of load-shedding have made backup power, solar and inverter systems mainstream, so demand for UPS and inverter transformers, chokes and harmonic reactors is strong.
VA Electricals designs and manufactures single-phase control transformers at its works in Bhosari, Pune. Every unit is built to your voltages and rating and tested in-house, then packed for export to buyers in Johannesburg, Ekurhuleni, Pretoria and across South Africa.
Built for 230 V single-phase / 400 V three-phase, 50 Hz, with secondaries such as 24 V, 110 V or 230 V for control circuits.
A single phase control transformer provides the voltage needed by control circuits in electrical and industrial equipment. It electrically separates the control circuit from the main power circuit while supplying a suitable control voltage to relays, contactors, timers, sensors and solenoid valves.
Panel builders and OEMs in South Africa use them where a compact, single-phase control supply is needed inside the cabinet, sized for the coil inrush of the contactors and relays it feeds.
Compact units for control panels, MCC panels and machine control cabinets.
