Vietnam has become one of Asia's fastest-growing manufacturing destinations. Industrial parks in Binh Duong, Dong Nai, Bac Ninh and Hai Phong build electronics, garments, furniture and machinery on the 380 V grid, and need dependable transformers and chokes.
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 packed for export to buyers in Ho Chi Minh City, Binh Duong, Dong Nai and across Vietnam.
Built for 220 V single-phase / 380 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 Vietnam 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.
Electronics and component factories in Bac Ninh, Bac Giang and Hai Phong run automated lines.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Garment, footwear and textile plants in Binh Duong and Dong Nai run large machinery parks.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Furniture, wood-processing and machinery makers run CNC and production lines.
Typical use: Correcting supply voltage for imported machines rated for a different voltage.
Panel builders in Ho Chi Minh City and Hanoi supply industrial park projects.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Vietnam's large solar sector needs inverters and power-conversion equipment.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Seafood, coffee and food processors run cold-chain and packaging lines.
Typical use: Keeping refrigeration and process motors at rated voltage.
Factories in Vietnam run long shifts in hot, humid conditions. Windings are oven-baked for moisture resistance, and each design is checked for temperature rise at your site's ambient.

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 export shipping dates.
Yes. VA Electricals manufactures buck boost transformers at its works in Pune, India and supplies buyers across Vietnam, including Ho Chi Minh City, Binh Duong, Dong Nai, Long An, Hanoi.
Yes. Units are built for the 220 V single-phase / 380 V three-phase, 50 Hz supply used in Vietnam, 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.
Shipped by sea from Nhava Sheva to Cat Lai, Cai Mep or Hai Phong, with air freight for urgent needs.
Yes. Share the ambient temperature, humidity and duty cycle at your plant. Windings are oven-baked for moisture resistance and the design is checked for temperature rise at your ambient.
Share your voltages, rating and quantity. Our engineers will send a technical offer for supply to Ho Chi Minh City, Binh Duong, Dong Nai or anywhere in Vietnam.
