High voltage interlock circuit enabled Amphenol FG-23R connector for utility truck electrical systems
Product Overview
The Amphenol ePower Connector Series is engineered for the rigorous demands of hybrid, electric vehicles, and utility truck electrical systems. Designed to operate at 800VDC to 1000VDC with continuous current ratings from 200A to 400A, this series leverages the patented RADSOK technology. This innovation significantly enhances current carrying capacity, reduces temperature rise (T-rise), and lowers resistance and mating force. The ePower connectors offer a 40% smaller footprint compared to traditional solutions like three EMI shielding cable glands, simplifying termination with shielded cable. Available in 2 or 3 power contact configurations, a single ePower 400A connector can replace multiple conventional connectors, thereby saving space and cost. Applications span both Military Aerospace and Industrial segments, including power converters, hybrid electric vehicles, heavy equipment electrification, two and three-phase motors, and starter generators.
