Residual current monitoring system VRCM16

for EV chargerfor the automotive industry

■ Features Type-A+6mA residual current module for EV charging pile protection. All-in-One highly-integrated digital output. ■ Standard Applicable for IEC 62955-2018 residual current requirements for RDC-PD. Applicable for GB/T 22794 and adapted to DC 6mA test. Self-check circuit 2 widing on the ZCT to generate simualted DC residual current. By using VDD to generate typical value = 6.53 mADC simulated residual current. This current is the most restricted tripping condition to test whether System is working correct. Digital signal flip threashold For avoiding the signal oscillation, tripping signal output flipping has been set with tripping threshold and recovery threshold. When tripping threshold IAT reached, the related X-OUT flip,and when the current decrease to the recovery threshold IÛR, the related X-OUT flip again, back to low level State. IÛT is set as 100% typical tripping value, and IAR is set as 55% typical tripping value.
