Technical Data

RCMU FUNCTION BRIEF OUTLINE

When the charging station is working , if there is a DC leakage current signal, the RCMU will immediately output a fault signal and cut off the output power within 300ms, ensuring the safety and reliability of personal and property. If the fault is eliminated, the charging station will automatically restart charging according to the program within 3S. Before charging, the RCMU module of the device will automatically carry out the accuracy and detection of the DC leakage current to ensure the safe and reliable operation of the device.

 

RCMU USE

RCMU SELF-CHECK FUNCTION

When the main circuit is not working, the leakage current is 0, and Vout is at low level (0V) at this time . (a)When the CHK PIN pin is set to high level (3.3-5V), Vout rises from low level to high voltage (Vcc) at this time. (b) When the CHK PIN pin is set to low level (0.2v), the Vout generated at this time drops to low level (0V); When the above (a) and (b) are completed, it is judged that the residual current sensor is functioning normally. When the readme function is not working , you can add a 0 ohm resistor to the CHK PIN pin and ground it.
