They are committed to environmental protection and has long implemented green manufacturing processes, recycling, waste management programs and has constructed environmentally-friendly green buildings.

 compact, user friendly, and feature-laden AC Frequency Drive to be used with 3-phase AC induction motors. It employs state of the art microprocessor technology which controls all drive functions. motor drives cover general purpose motor control applications from 0.40 to 55.0 kW (0.50 up to 75.0 Hp) and offer a complete set of features and options usually available only on larger drives

Variable Frequency Drive (VFD)

A variable-frequency drive (VFD also termed adjustable-frequency 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.

VFDs are used in applications ranging from small appliances to the largest of mine mill drives and compressors. About 25% of the world’s electrical energy is consumed by electric motors in industrial applications, which are especially conducive for energy savings using VFDs in centrifugal load service: however, VFDs’ global market penetration for all applications is still relatively small. That lack of penetration highlights significant energy efficiency improvement opportunities for retrofitted and new VFD installations.

Over the last four decades, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques, and control hardware and software.

VFDs are available in a number of different low- and medium-voltage AC-AC and DC-AC topologies.
