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.
