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, three-phase and multi-tap 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 control secondaries such as 24 V, 110 V or 230 V, or any voltage your panel needs.
A control transformer steps the incoming supply down to a stable control voltage for contactors, relays, timers, solenoid valves, PLC I/O and indicator circuits, while electrically isolating the control circuit from the power circuit. It is designed to hold its secondary voltage during the high inrush current drawn when contactor coils and solenoids pick up.
For panel builders in Kolkata, a correctly sized control transformer prevents nuisance drop-outs of contactors and relays when several coils energise together, and keeps the control circuit isolated from the power circuit.
For control panels, MCC panels, relay and contactor circuits, solenoid valves and machine control circuits.
