HEP 100W to 320W Harsh Environment Power Supplies

MEAN WELL HEP 100-320W Harsh Environment Power Supplies are high-grade AC/DC power supplies with low noise and the ability to operate in extreme conditions and temperatures. The HEP devices provide rated power of 100W, 150W, 185W, 240W, or 320W in an aluminum case with an interior that is fully potted with heat-conducted silicone. These power supplies offer IP65 protection against the ingress of dust and water (optional IP68 level models are also available). The devices also feature up to 10G anti-vibration capability.
