To realize energy-saving operation.

Auto voltage

regulation (AVR)

When the network voltage changes, it can regulate

PWM output automatically to maintain constant voltage.

Built-in PID This can form a convenient closed-loop control system

(CLCS),and is applicable to pressure control, flow

control and other process control.

reset signal and etc.

Output signal Programmable relay, open-collector output, failure signal output and etc.
Multi-function analog

and digital output


This can realize the output of frequency, current and other physical

quantity by outputting 0~20mA DC signal and 0~10KHz

digital signal

  Braking function Dynamic braking With an external braking resistor, the maximum braking

torque may reach 100% .
