US industrial technology manufacturing company Littelfuse has introduced its RCMP20 Residual Current Monitor Series for EV charging stations.
The RCMP20 Series is designed to offer high performance and flexibility while supporting higher charging currents than alternative products on the market, according to the company.
The monitors have a large current transformer (CT) aperture, while integrated conductors that have higher cross-sectional areas provide enhanced thermal management, reducing printed circuit board (PCB) temperature. The integrated PCB with optional conductors streamlines installation, reduces the number of components and simplifies assembly, allowing for more compact designs while still meeting safety code requirements.
The modules are designed to resist electromagnetic interference (EMI), minimizing false circuit trips and improving overall charging station reliability.
The RCMP20 Series has vertical and horizontal mounting options and 2-4 integrated conductors, allowing design engineers to optimize the use of space and adapt to various charger configurations.
The RCMP20-03 module is designed to help enhance the safety of portable charging stations by monitoring AC and DC residual currents. When a ground fault, leakage or residual current exceeds the threshold, the RCMP20-03 triggers a circuit shutdown, preventing electrical hazards.
The RCMP20-01 module is specifically designed to detect DC residual currents in permanent charging stations that Type A RCDs overlook. When DC fault currents exceed the threshold, it signals a trip to a connected switching device, ensuring user protection.
Littelfuse also recently expanded its range of Ultra Junction X4-Class 200 V Power MOSFETs for battery storage and power supply applications.
