Servo & Step Down Transformers
What We Offer
J-TECH INDIA provides heavy-duty power conditioning solutions engineered to protect sensitive CNC machinery, automation lines, and industrial electronics. Built with high-grade copper/aluminum windings and fast-acting servo control, our Servo & Step Down Transformers (15 KVA to 100 KVA) deliver stable voltage output, correct voltage mismatches, and eliminate power fluctuation risks across your shop floor.
Industrial Servo & Step Down Transformers (15 KVA – 100 KVA)
J-TECH INDIA is a leading supplier of custom-engineered Servo Voltage Stabilizers and Isolation Step Down Transformers in India, designed specifically for CNC VMCs, HMCs, laser cutting systems, turning centers, and industrial automation equipment. Ranging from 15 KVA to 100 KVA capacity, our transformers bridge the voltage gap between incoming utility lines and imported or high-precision machinery requiring exact operational voltage (e.g., stepping down 415V to 380V/220V/200V).
Constructed with prime-grade CRGO laminations, heavy-duty buck-boost transformers, and digital microcontrollers, our power units maintain stable, regulated output even under severe grid fluctuations. Every unit is engineered for continuous 24/7 duty, low temperature rise, and maximum efficiency to safeguard expensive machine controllers and drives from electrical damage.
You Need J-TECH Servo & Step Down Transformers When:
- Operating imported CNC machinery requiring specific step-down voltages (380V, 220V, or 200V)
- Experiencing frequent voltage spikes, sags, or unbalances on the industrial grid
- Protecting sensitive CNC controllers, servo drives, and PLC units from electrical burnouts
- Reducing machine downtime caused by under-voltage or over-voltage tripping
- Requiring clean, noise-free galvanic isolation between grid supply and machine circuits
- Ensuring steady cutting performance and precision motor torque on heavy loads
An essential power protection unit for CNC machine shops, plastic molding plants, automotive component manufacturing, and automated assembly lines.
