Key Features
- Speed control: By adjusting the output frequency, the motor speed can be smoothly and infinitely adjusted to meet the production process requirements.
- Energy saving operation: Adjust the motor speed according to the load demand, avoiding energy waste caused by traditional adjustment methods such as baffle adjustment, and achieving significant energy-saving effects.
- Protection function: Provides multiple protections such as overcurrent, overvoltage, overload, short circuit, and grounding to ensure the safe operation of equipment and motors.
- Power factor optimization: reduce reactive power loss, improve power factor of the power grid, and reduce harmonic interference.
Working Principle
- Rectification: Convert input AC power into DC power through a rectifier bridge.
- Filtering: Filtering DC electricity through capacitors or reactors to smooth out voltage fluctuations.
- Inverter: Using IGBT and other switching devices to invert DC power into three-phase AC power with adjustable frequency and voltage.
- Control unit: Adjust the output frequency and voltage according to the set parameters and requirements to achieve precise control of the motor.
Case
- Central air conditioning: By controlling the freezing pump and cooling pump through variable frequency speed regulation, the energy-saving effect is significant.
- Injection molding machine: controls oil pump pressure or flow rate, saves 20% -52% electricity, replaces traditional proportional valve throttling speed regulation.
- Steel rolling mill: realizes low-frequency load starting, synchronous operation between frames, and constant tension control.
