ZFeng 900 Series 22Kw-T-P General Vector Variable Frequency Drive

ZFeng 900 Series 22Kw-T-P General Vector Variable Frequency Drive

Variable frequency drive (VFD) is a device that converts fixed frequency AC power into adjustable frequency electrical energy through the on-off action of power semiconductor devices (such as IGBT). It integrates frequency conversion technology and microelectronics technology, mainly used for precise control of the operation of AC motors.

A frequency converter is an electrical energy control device that converts power frequency power into adjustable frequency electrical energy through the on-off action of power semiconductor devices. Its main functions include speed regulation, energy saving, providing overcurrent/overvoltage/overload protection, and changing power factor.

Core functions and advantages

• Speed regulation and energy saving: By adjusting the power frequency to change the motor speed, smooth soft start (reducing starting current shock) and stepless speed regulation can be achieved. Energy savings of 20% -50% can be achieved in loads such as fans and pumps, reducing mechanical wear and tear.
• Protection function: Provides multiple protections such as overcurrent, overvoltage, overload, short circuit, and grounding to ensure the safe operation of the equipment.
• Power factor optimization: reduce reactive power loss, increase active power of the power grid, and reduce harmonic interference.
