DC insulation resistance above 1000 MΩ. Noise rejection factor of 80–100 dB. Conforms to IS 2026.
3 KVA to 1000 KVA • Delta-Star (Dy11) • Harmonic Cancellation
Scaled for industrial loads, this three-phase isolation transformer adds the benefit of Dy11 vector grouping — a 30° phase shift that cancels triplen harmonics generated by VFDs, rectifiers, and switched-mode power supplies. Available in air-cooled and oil-cooled configurations. Siemens Grey enclosure with wheel and lifting hooks for easy installation. CRGO/CRNGO core for maximum efficiency. Conforms to IS 2026.
Single & Three Phase • 2A to 100A • Stepless 0–270V / 0–470V
The Dimmerstat (or Variac) gives the operator complete, smooth, stepless control of AC output voltage from zero to above the supply voltage — essential in testing laboratories, process heating, lighting rigs, motor speed testing, and educational electronics benches. Wound with high-conductivity copper. Available in manual or optional motorised configurations. Single-phase (0–270V from 240V supply) versions available in open-frame or enclosed box types.
Single & Three Phase • 2A to 100A • Stepless 0–270V / 0–470V
The three-phase CVAT delivers simultaneous stepless voltage control across all three phases, maintaining phase balance throughout the range. Suitable for three-phase motor testing, load banks, industrial furnace control, and high-power laboratory setups. Same construction quality as the single- phase model with copper winding and available motorised option.
Transformer voltages can be designed as per customer requirements. Customization available on request.
1 KVA to 10 KVA • Pure Sine Wave • Solar Compatible
A true online double-conversion UPS: mains power is continuously rectified to DC and re-inverted to clean AC, so the load always runs from the inverter — with absolutely zero transfer time during a mains failure. IGBT-based PWM technology with output isolation transformer produces a pure sine wave output (THD <3%). Handles overloads up to 150% for one minute. Full LCD display of input, output, battery, and frequency parameters. Protections cover every failure mode: overload, surge, short circuit, over-temperature, battery deep discharge, and over-charge.
