Automatic energy-saving operation

Auto optimize V/F curve according to the load changes to realize the 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  .
