MD0630T01A EV Charger Testing RCD Transformer 6mA DC 30mA AC Earth Leakage Current Detection Device

Product Description

MD0630T01A is an automotive grade leakage current sensor also called residual current monitoring (RCM), residual current detection (RCD), differential current sensor, earth leakage current detector and fault current sensor. Dedicated to detect to DC, AC and DC+AC leakage current measurement. It has the characteristics of accurate measurement, small size and integration. The RCD sensor can be set separately for AC and DC leakage and has a digital output function.  When an electric shock or leakage fault occurs in the circuit, the secondary side of the transformer outputs a mA level current (DC 6mA, AC 30mA), so that the equipment on the connected secondary line will be protected (cut off the power supply, alarm signal, etc.)  

This RCD detects DC currents flowing in an AC system. For example, in electric vehicle charging stations or from solar panels. DC currents flowing in an AC system may cause a Type A RCD or a Type F RCD to be blinded. This RCD module can be used to detect any DC current level above 6mA and its output can be used to operate a relay or a contactor to disconnect the AC supply, and display an error message on the screen of EVSE system, and wait for a user to reset the error. In addition, our delivery time is also guaranteed.

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.
