Technical Characteristics

Input voltage is 660V (±15%).

Input frequency ranges from 47 to 63Hz.

Output voltage ranges from zero to rated input voltage. Output frequency ranges from 0 to 400Hz.

Built-in PID function can realize PID closed-loop control conveniently.

Built-in RS485 communication supports MODBUS-RTU protocol.

Multiple parameters are used for online monitoring and on-line adjustment.

Prominent characteristics of soft start and soft stop

The speed regulation device gives rapid response to varying load.

Rated torque output at low speed

With strong overload capacity, the G model machine can continue working for 60s with 150% rated current, and 10s with 180% rated current.

The P model machine can work constantly for 60s with 120% rated current, and 1s with 150% rated current.


The medium voltage AC drive can be applied in the belt conveyors, scraper conveyors, fans, coal digging machines, water pumps, submersible pumps, water injection pumps, etc.
