MD0630STA-P Insulation Monitor Type B AC DC Current Sensor Earth Leakage Detection RCD for Fault Protection

The Residual Current Monitor (RCM) is intended for the detection of DC and/or AC residual currents in 50Hz/60Hz AC or DC installations. The RCM is ideally suited for use with Electric Vehicle charging cables (Mode 2 Protection) and EV charging stations (Mode 3 Protection). Residual current detection options for IEC-based requirements are 30mA AC or 6mA DC or both, and 20mA AC & 6mA DC for UL requirements. 

It can not only detect AC fault current, DC pulsing, and smooth DC fault current, but also sinus wave AC fault current at a high frequency up to 1kHz. IVY MD series leakage current sensors are optimized for fast, low-cost assembly, combined with the highest product and production quality. 

In addition to the use of charging piles. Also suitable for medical instruments, solar inverters, UPS, smart homes, industrial machines, heat pumps, power distribution units, etc. There is a DC component leakage scenario. Provide more reliable protection. Protecting personal and electrical equipment safety.

Pin Definition

Product Application

The AC/DC sensitive residual current monitor allows early detection of insulation faults and detects differential currents with AC as well as DC components in grounded voltage systems (type B). 

This RCD sensor 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 sensor can be used to detect any DC level above 6mA, and its output can be used to operate a relay or a contactor to disconnect the AC supply, display an error message on the screen of the EVSE system, and wait for a user to reset the error.
