- Primary-Side Regulation (PSR) non-isolated high powerfactor (HPF) system supports constant voltage andcurrent-limiting output. 

-Compatible with Remote Controller Mode and RegulatorMode ; supports automatic switching between remotecontroller mode and regulator mode. 

-Supports 4-speed and 5-speed Regulators. -Regulator Mode, rated operating voltage:200Vac~250Vac. -Regulator Mode enables low-speed level startup underinput voltage of 200Vac and above. 

-Remote Control Mode supports wide voltage operation inthe range of 110Vac~325Vac. -Control mode: torque control, limited power, limitedspeed, positive and negative electronic brake. -Supports RF433 remote control. 

- PCB integrated molding, high production efficiency, lowcost. 

-MCU integrates carrier and comparator, and the currentsampling difference signal is directly input without biasvoltage. 

- AC Line Over Voltage Protection,the overvoltageprotection point is configurable, supporting a maximumof 325Vac. - Driver output open circuit, short circuit, a cycle by acycle to limit the current protection. 

-Complete protection functions: over voltage, undervoltage, over current, blocking, phase deficiency, internalpower supply monitoring and protection.
