Industrial power connectors Amphenol RAD-11-90 designed to simplify termination with shielded cables
Product Overview
The Amphenol ePower Connector Series is engineered for the demanding requirements of hybrid electric vehicles, utility trucks, and other industrial electrical systems. These connectors operate at high voltages (800VDC to 1000VDC) and continuous current ratings (200A to 400A), incorporating the patented RADSOK technology. This innovation offers significant advantages, including higher amperage capacity, reduced T-rise, lower resistance, and lower mating force. The ePower Series provides 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, leading to substantial space and cost savings. Applications span Military Aerospace and Industrial segments, including power converters, hybrid electric vehicles, heavy equipment electrification, two and three-phase motors, and starter generators.
