Variable Frequency Drives (VFD) / Variable Speed drives (VSD)
for control regulation of motor speed, energy saving
A variable-frequency drive (VFD) or adjustable-frequency drive (AFD), variable-voltage/variable-frequency (VVVF) drive, variable speed drive, AC drive, micro drive or inverter drive is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
We supply standard duty, heavy duty, industrial duty for HVAC, pump, compressor, motors, Fans etc. applications. We offer reputed brands and make like ABB, Danfoss, Crompton Greaves, Schneider, Fuji, Eaton, Johnson Controls, Siemens, Mitsubishi etc. These are available in such as 100 to 120 V, 200 to 240 V, 380 to 480V or 525 to 600/690 V power supply, ranging from low rating like 0.37Kw to 800~ 1000 kW or more.
We offer major varieties of VFDs including pulse-width modulation (PWM), current source inverter and voltage source inverter.
