High quality 220v 250W PWM DC motor speed controller

High quality 220v 250W PWM DC motor speed controller   

Reliability and protection mechanisms
Input analog signal isolation, improve system reliability and security
Current limiting protection, to accurately collect motor current
Increase the temperature sensor to achieve over-temperature protection;
Circuit board need to spray three anti-paint to improve reliability

【Wiring】

【0 ~ 5VDC or 0 ~ 10VDC input connection】

[R] connected to 0 ~ 5V analog

[G] connected to the negative power supply, such as single-chip negative power supply, or PLC power supply negative;

[K] side directly connected MCU IO port or PLC output port; if no switch function, you can use a wire connected to [G] side

【4 ~ 20mA input connection】

[R] connected to 4 ~ 20mA analog

[G] to the negative power supply, such as the negative power supply PLC;

[K] side of the PLC output port; if no switch function, you can use a wire connected to [G]

【Potentiometer connection method as shown below】
