Simple PLC, multi-speed operation

Up to 16-speed operation through built-in PLC or control terminals

Built-in PiD

Easy to achieve process control and closed-loop control systems

Automatic voltage regulation (AVR)

The output voltage can be kept constant automatically when the grid voltage changes

Overvoltage / overcurrent stall control

The current / voltage can be limited automatically during operation to prevent frequent overcurrent / overvoltage tripping

Quick current limiting function

Overcurrent faults can be minimized to ensure the normal operation of frequency converters
