The HEP-600 series power supplies complement the family of high-quality and low-noise AC/DC industrial power supplies from MEAN WELL, which are available with rated outputs ranging from 100 W to 600 W. Thanks to their aluminum housing and complete filling with thermally conductive silicone, the HEP series power supplies are suitable for use in particularly harsh environments: high humidity or dust levels, extreme temperatures, strong vibrations, at high altitudes, and in poorly ventilated conditions. With an efficiency of up to 96% and cooling through free air convection, they operate reliably at ambient temperatures between -55 and +70 °C. The HEP series covers a wide input voltage range of 90 to 305 VAC and is available in output voltages of 12 V, 15 V, 24 V, 36 V, 48 V, and 54 V. This makes them suitable for industrial applications of all kinds worldwide, such as telecommunications equipment, outdoor display and advertising boards, and oil or mining installations.
