Product Introduction
MD0630T01A-2 is an automotive grade smallest leakage current sensor designed for portable AC charger also called residual current monitoring (RCM), residual current detection (RCD), differential current sensor, leakage current detector and fault current sensor. Multiple types leakage current detection(AC/A/F/B/B+), dedicated to detect to DC, AC and DC+AC leakage current measurement. The internal parts of the portable charger should be as small as possible, our new leakage detector is small and lightweight, which just meets this requirement. This residual current monitor will detect DC and AC residual currents in 50Hz/60Hz AC installations according to IEC62955. It's primarily intended for use in Electric Vehicle charging stations to disconnect the supply to the Electric Vehicle under a DC residual fault current condition. It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs.
In electric vehicle charging if the DC fault current is greater than 6mA, it could change the characteristics of a Type A RCD due to its core saturation, resulting in the type A failing to trip and a lack of detection of the DC fault. In this instance, the risk of electric shock is increased, and safety is compromised. IVY has launched a new RCD sensor that is designed to detect a DC earth fault, which is more cost-effective than using a Type B RCCB. In the event of a dangerous electrical fault, the sensor will output an alarm signal (by setting the leakage alarm value). This new RCD sensor enables compliance with the updated IEC62955:2018 and reduces the cost of developing electric vehicle charging solutions.

EV Charging Application
Where the EV supply equipment is equipped with a socket-outlet or vehicle connector for AC use in accordance with IEC 62196(all parts), protective measures against DC fault current shall be taken. The appropriate measures shall be:
Type B RCD or Type A RCD and appropriate equipment that ensures the disconnection of the supply in case of DC fault current above 6mA
In the IEC 61851-1, it is clearly specified that residual current protection in AC charging equipment shall adopt type B or type a +6ma smooth DC RCD. At the same time, it is clearly stated in the relevant IC-CPD standard iec62752-2018 that the residual current protection device shall detect smooth DC 6mA.
