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 buck boost 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 the buck or boost amount chosen to bring your supply to the equipment's rated voltage.
A buck boost transformer raises (boosts) or lowers (bucks) the supply voltage by a small amount so equipment receives the voltage it is designed for. Because it only handles the correction voltage, it is far smaller and more economical than a full isolation transformer for the same load.
For sites in Kolkata where the supply sits a little above or below what equipment is rated for, a buck boost transformer corrects the voltage economically, without a full-size transformer.
Lowers a high supply voltage to protect equipment rated for a lower voltage.

Designed around your measured supply range and load.
Durgapur and the Howrah engineering belt serve steel, foundry and heavy-engineering industries.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Haldia hosts refinery, petrochemical and port-based process plants.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Panel builders in Howrah and Taratala supply projects across East India.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Electronics and IT firms in Salt Lake Sector V need dependable UPS power.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Food processing, tea and FMCG plants run packaging and process lines.
Typical use: Keeping refrigeration and process motors at rated voltage.
Coal and mineral operations in the eastern belt run conveyors, pumps and crushers.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Plants in Kolkata see summer heat in panel rooms, monsoon humidity and supply fluctuations. Share your duty cycle and ambient conditions, and we design the rating, insulation and construction to suit.

Of transformer design and manufacturing experience behind every unit.
ISO 9001:2015 quality system and CE conformity under the Low Voltage Directive.
Voltages, ratings, terminals and mounting made to match your design.
Production planned around your project schedule and delivery dates.
Yes. VA Electricals manufactures buck boost transformers at its works in Pune, India and supplies customers across Kolkata, including Howrah, Dankuni, Taratala, Kalyani, Bantala.
Yes. Units are built for the 230 V single-phase / 415 V three-phase, 50 Hz supply used in Kolkata, with the buck or boost amount chosen to bring your supply to the equipment's rated voltage.
When the supply only needs a small voltage correction and isolation is not required. A buck boost unit handles only the correction voltage, so it is smaller, lighter and lower in cost for the same load.
VA Electricals operates an ISO 9001:2015 certified quality management system and holds MSME ZED Bronze certification. Its products carry CE conformity under the Low Voltage Directive 2014/35/EU, covering transformers up to 200 kVA.
Dispatched by road from our Pune works, about 1880 km away, packed to protect windings and terminals in transit.
Yes. Tell us the ambient temperature, duty cycle and supply conditions at your plant, and we design the rating, insulation and construction to suit.
