The high-quality and low-noise AC/DC industrial power supplies are available with rated powers 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 spaces. To protect against dust and water ingress, the power supplies have an IP65 protection rating (IP68 available upon request) and feature vibration resistance up to 10 G. With an efficiency of up to 96% and cooling through free air convection, they operate reliably in 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 systems, outdoor display and advertising boards, oil or mining installations.
