Plastic power connector Amphenol ELR4A03 designed for demanding hybrid electric vehicle applications
ePower-Lite Connector Series
The Amphenol ePower-Lite is a robust plastic power connector series specifically designed for the demanding requirements of the hybrid electric vehicle (HEV) market. Offering 2, 3, and 4-pole configurations, this series features a durable plastic shell capable of withstanding high temperatures up to 125C and providing essential dielectric protection. Integrated with patented RADSOK technology, ePower-Lite connectors deliver superior performance, including higher amperage capacity, reduced temperature rise (T-rise), lower voltage drop, and minimized resistance. Its compact, lightweight plastic shell design ensures a small footprint, making it ideal for space-constrained EV applications. The connectors are field installable and repairable, further enhancing their practicality. For added security and reliability, ePower-Lite includes a Connector Position Assurance (CPA) to confirm proper mating. These combined attributes establish the ePower-Lite as a leading interconnect solution for the EV and Hybrid markets.
