MD0630STA-P PCB Mount Type B AC DC Current Sensor Earth Leakage Detection RCD for Fault Protection
MD0630STA-P is a leakage detection RCD Type B current sensor for PCB (also named as RCM/RCD) with digital output of fault detection and integrated self-testing functions. The sensor can be used to build a IEC62955 Residual Direct Current – Detecting Device (RDC-DD) together with EV charging controller and protection devices inside EV chargers, which can meet AC/DC residual current protection request defined in IEC 61851-1. With the characteristics of high sensitivity, accurate measurement, small size, and integration. When a DC leakage current of 3~6mA or an AC leakage current of 15~30mA is detected, an alarm signal will be output.
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 are 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 are 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 home, industrial machines, heat pumps, power distribution unit etc. There is a DC component leakage scenario. Provide more reliable protection. Protecting personal and electrical equipment safety.

Product Application
The AC/DC sensitive residual current monitor allows an 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 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.
