Product Description

What's a variable frequency drive for?

Variable Frequency Drive (VFD) is a power control device that controls the speed and output power of an electric motor by adjusting the frequency and voltage of alternating current. It is widely used in industrial automation, HVAC (Heating, Ventilation, and Air Conditioning), water pumps, fans, machine tools, and other fields to achieve energy-saving, precise control, and soft start functions.

The core functions of a frequency converter

Speed control
Adjust the motor speed by changing the output frequency (0Hz to several hundred Hz) to meet different operating conditions.

Energy saving operation
By adjusting the speed instead of valve/baffle control in loads such as fans and pumps, energy consumption can be significantly reduced (with an energy-saving rate of up to 30%~50%).

Soft start/stop
To avoid current surges during direct motor start-up (up to 5-7 times the rated current) and extend equipment lifespan.

Protection function
Protection against overcurrent, overvoltage, undervoltage, overheating, short circuit, etc., enhances system reliability.

Specification
