Kolkata anchors East India's industry. Howrah's engineering units, the Dankuni and Uluberia industrial parks, and the Durgapur and Haldia belts serve steel, power, port and process industries across the region.
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 delivered by road to customers in Howrah, Dankuni, Taratala and across Kolkata.
Built for 230 V single-phase / 415 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 Kolkata 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.
