Description

The BRCS01C is an advanced AC/DC residual current sensor designed for electric vehicle (EV) chargers, ensuring compliance with the residual current protection requirements outlined in IEC 61851-1 for Mode-3 EV charging. It features two separate fault signal outputs: one pin for detecting Type A 30 mA AC and 6 mA DC residual currents, and another pin dedicated exclusively to detecting 6 mA DC residual current. This dual-output configuration makes the BRCS01C suitable for built-in RDC-PD, Type-A mRCD+RDC-MD, and RDC-MD applications in AC EV chargers. The BRCS01C is available in two interface versions: 12V DC and 5V DC. The 12V version includes an integrated MOSFET with a maximum switching current of 500 mA, enabling direct coupling to relays or contactors within EV chargers. The 5V version offers superior protection against transients, ensuring stable performance even in dynamic environments.
