BLDC+LED Display+RF433 Fan Controller
BLDC 风扇
- PSR isolation HPF system constant voltage currentlimiting output.
- 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.
- PCB integrated molding, high production efficiency, lowcost.
- 7-speed wind speed control. Main PCB supports 433MHz remote control or IRremote control.
- External infrared signal receiver and RGB lamp beadsmall board-Supports audio and visual prompts, buzzer and RGBindicator lights.
-MCU integrates carrier and comparator, and the currentsampling difference signal is directly input without biasvoltage. -Support single resistor/triple resistor sampling optional.
-Control mode: torque control, limited power, limitedspeed, positive and negative electronic brake.
-Complete protection functions: over voltage, undervoltage, over current, blocking, phase deficiency, internalpower supply monitoring and protection.
