Product Overview
MD0630T01A is an automotive grade high sensititivity AC DC leakage current sensor which has the characteristics of accurate measurement, small size and integration. The leakage sensor can be set separately for AC and DC leakage. An alarm signal is generated when the set current is reached. The leakage sensor has a digital output function, which can directly read the current value of DC and AC. Which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD), differential current sensor, earth leakage sensor and fault current sensor etc. it is ideally suited for use with Electric Vehicle charging cables (Mode 2 Protection) and EV charging stations (Mode 3 Protection). When a leakage current that exceeds the rated AC or DC level is detected, It will signal to the Smart EVSE.
Charging of electric vehicles at a standard wall socket or a wall box requires protection devices against DC fault currents to avoid electric shock. Installed type A residual current circuit breakers (RCCBs) are unable to identify and deactivate DC fault currents. IVY differential current sensors offer the opportunity to save the cost and space for a costly type B RCCB in IC-CPD or wall boxes. It can be used to measure leakage currents including DC, AC, and AC and DC stacks, generally used as a DC leakage current detection and protection in equipment that uses DC operation. In addition to normal AC, can detect high-frequency AC and pure DC earth leakage currents. MD series RCD sensor is an ideal protection device against different leakage currents in applications of electric vehicle charging, photovoltaic systems (solar panels), industrial device, medical device, DC screen, fire distribution cabinet, IOT field etc.

EV Charging Application
Within an electrical vehicle, the AC/DC conversion process ensures that charging of the electrical vehicle occurs within the confines of the electrical vehicle itself. Electrical vehicle manufacturers state that, in the case of a 3-phase charger, DC current leakage can occur. The same phenomenon is replicated in the case of a single-phase charger with boost stage.
The electrical vehicle cannot be fully isolated and therefore a proper protection against DC residual current is needed in the system. The protection can be accomplished either with a 6mA detection device (Residual direct current detecting device, RDC-DD) inside the charger or with a Type B RCD either inside the panel board or inside the charger itself.
