Sri Lanka's apparel, rubber, tea and food industries are concentrated around Colombo and its export processing zones at Katunayake and Biyagama. Its close shipping links with India make Indian-made transformers and chokes a practical choice.
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 Colombo, Katunayake EPZ, Biyagama EPZ and across Sri Lanka.
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 Sri Lanka 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.

Apparel and textile plants in Katunayake, Biyagama and Koggala EPZs run sewing and finishing machinery.
Typical use: Single-phase control voltage for relays, contactors and solenoids.
Rubber, glove and tyre manufacturers run mixers, presses and curing lines.
Typical use: Single-phase control voltage for relays, contactors and solenoids.
Tea factories, food processors and beverage plants run drying and packaging equipment.
Typical use: Control circuits on filling, sealing and packaging machines.
Panel builders in Colombo supply industrial, hotel and commercial projects.
Typical use: Single-phase 230, 110 or 24 V control supply for relay and contactor circuits.
Rooftop and utility solar systems need inverters and power-conversion equipment.
Typical use: Single-phase control voltage for relays, contactors and solenoids.
Hotels, hospitals and commercial buildings run large HVAC systems.
Typical use: Control supply for HVAC starters, dampers and thermostats.
Factories in Sri Lanka deal with monsoon humidity, voltage fluctuation and frequent changeover to captive generators. Windings are oven-baked for moisture resistance, and ratings are chosen with margin for supply swings.
