1,Can support AC and DC input, there is no problem of power polarity. 2,Ultra-high voltage application range. DC supports 15-160VDC. Input. The AC supports 12-110VAC input. 3,Oversized radiator with mounting holes. 4,Super high power control, can support 5A current. 5,In addition to the PWM speed adjustment inside the board, it can also support external PWM signal input to control the speed adjustment. The external PWM input requirements are: level 3.5-12V VPP, frequency 1K-5KHZ, and duty cycle 0% -93. %. Especially suitable for MCH3 spindle speed control. When equipped with external PLC control, a 2K resistor should be connected in series. 6,Support a wide range of motors. It can basically control the speed of most DC motors in the market. As long as the DC resistance of the motor is greater than a 2 ohm DC motor. 7,Equipped with fuse 5A, better protection performance. 8,With power indicator, it is more convenient to use. 9,High-power voltage-limiting resistors are used to reduce overall module heating and improve work stability.
