The RCM14-04 system is a residual current monitor designed to detect ac and dc residual currents in UL 2231-compliant EV charging systems, where such currents may occur under fault conditions. The system includes a 14 mm aperture current transformer (CT) and a sensor PCB for direct PCB mounting by OEMs. It detects 56 mA dc and 20 mA ac residual currents in dc, single-phase, or three-phase installations and functions equivalently to the RCM14-04. Fully compliant with CCID20 detection requirements as defined by UL 2231-2.
- Operates from a 12-24 V dc supply
- External Test Facility
- "Fault" Signal Output
- Compatibility with common control voltages and redices OEM inventory complexity
- Ability to verify to correct operation of the device
- Offloads fault detection from the main control system, simplifying and reducing development time
