MEAN WELL HEP Series: Industrial Harsh Environment Power Supplies
Advanced Product Features
The HEP series is a rugged, high-efficiency power solution engineered to perform where standard power supplies fail. It is designed to be the backbone for outdoor, high-humidity, and dusty installations.
- Extreme Environmental Protection: IP67-rated metal housing, fully potted with thermal-conductive silicone to ensure protection against dust, water, and humidity.
- Wide Temperature Range: Reliable operation in extreme thermal conditions from -55°C to +70°C.
- High-Efficiency Design: Industry-leading conversion efficiency (up to 96%), minimizing power loss and operational costs.
- Robust Surge Immunity: Designed to withstand up to 10kV (surge immunity) to protect against grid instabilities in harsh outdoor environments.
- Fanless Operation: Completely silent, conduction-cooled design eliminates maintenance-prone cooling fans.
- Smart Features: High-power models (1000W+) include CANBus/PMBus communication interfaces and PV/PC programmable output functions.
