Product Introduction
MD36DA-C is a high-sensitivity and cost-effective leakage current sensor, which is also called residual direct current monitoring module, residual direct current monitoring device(RDC-MD), residual direct current detecting device(RDC-DD), residual direct current protective device (RDC-PD). IEC 61851-1 specifies that, to ensure electrical safety during charging, protective measures must be in place that can detect and respond to smooth DC residual currents exceeding 6 mA.
The RDC-DD is a compact solution designed to be cable-mounted. When a DC leakage current of 3~6mA is detected, an alarm signal is output. It can judge whether the sensor is in a normal working state in real time through the self-test function. It is primarily intended for use in EV charging stations to output an alarm signal under a DC residual fault current condition. In addition to the use of charging piles. Also suitable for solar inverters, UPS, smart home, industrial machines, medical devices, power distribution cabinets, etc. There is a DC component leakage scenario. Provide more reliable protection. Protecting personal and electrical equipment safety.

EV Charging Station Components
As the residual current protective devices (RCD) is widely used in low-voltage distribution system to prevent electric shock accidents, leakage damage of electrical equipment and fire caused by electrical leakage. RCD is widely used as a basic electrical protection device in the field of electric vehicle charging application (IC-CPD and AC Charger/Wall-box).
