Overview

The ePower-Lite series is engineered to handle high voltage and high current loads in a wide range of applications. These lightweight connectors are designed to provide easy installation, superior sealing, and enhanced performance, making them ideal for the electrification of vehicles and other power-hungry industrial systems. The ePower-Lite Mini offers a smaller form factor with the same high voltage capabilities, making it the perfect choice for applications requiring space-saving designs.

The standard ePower-Lite connector features Amphenol’s innovative RADSOK® technology, helping provide low contact resistance and minimal temperature rise under high current loads. The ePower-Lite Mini and ePower-Lite Mini X use compact terminal designs optimized for smaller form factors and space-constrained applications, supporting reliable power transfer, environmental sealing, and system design flexibility across a broad range of electrification platforms.

The ePower-Lite Mini family now includes ePower-Lite Mini X, a compact 2-pole high-voltage connector option for space-constrained applications such as DC/DC converters, high-voltage heaters, and high-voltage climate compressors. Mini X supports sealed, touch-safe high-voltage connectivity with optional HVIL and EMI configurations, helping engineers address safety, packaging, and environmental requirements in EV, HEV, FCV, heavy equipment, automation, and industrial electrification platforms.

Key Features & Benefits
