power distribution Amphenol RAD-08-25 connector for hybrid electric and heavy equipment applications
Product Overview
The Amphenol ePower Connector Series is engineered for the rigorous demands of hybrid, electric vehicles, and utility truck electrical systems. These connectors operate at 800VDC to 1000VDC and offer continuous current ratings from 200A to 400A. They incorporate the patented RADSOK technology, providing higher amperage, reduced T-rise, lower resistance, and reduced mating force. The series offers a 40% smaller footprint compared to three EMI shielding cable glands and simplifies termination with shielded cable. Available in 2 or 3 power contact configurations, a single ePower 400A connector can replace multiple conventional connectors, leading to significant space and cost savings. 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.

Value-Added Cable Assemblies
Amphenol Industrial offers value-added cable assembly services for ePower harnesses, manufactured in Nogales, Mexico, or Zhuhai, China. These services ensure quality harnesses from component experts, reduce lead times, and provide a single source for components. Amphenol can procure bulk cable or use customer-specified materials, add coverings, clips, and other components, or ship blunt cut leads. Low voltage cable assemblies can also be accommodated. Amphenol positions these services as a cost-effective and high-value alternative.
Alternate Designs and Cable Assemblies
Information available for 700 Amp and 500 Amp configurations (3-pin design also available). Right Angle Over Molded assemblies are available and ship as a cable assembly (inquire about PN ePRAXX11).
