Rugged 240W and 320W Industrial AC-DC Power Supplies

In order to meet the demands for high-grade ac-dc power supplies with low noise and the ability to operate under highly-humid, highly-dusty, highly-oily, highly-salty, ultra low or high temperature, heavily-vibrating, high-altitude and poor ventilation environments, Mean Well unveiled the 240W/320W HEP-240/320 series. These two series adopt aluminum case and the interior is fully-potted with heat-conducting silicone that provides both series with the IP65 protection against the ingress of dust and water (IP68 level optional models are also available) and the up to 10G anti-vibration capability.

Moreover, they are able to work under the ambient temperatures between -55 and +70 degrees C by free air convection. These power supplies are designed for industrial control applications running in harsh environment all over the world, such as outdoor telecommunication equipment, outdoor electronic signage and billboards, and petroleum plants or mine shaft facilities.

These power supplies have a universal input capability from 90- to 305-Vac and include active power factor correction. These fanless designs are cooled by free-air convection and have conversion efficiencies up to 94.5%. They meet kKV surge immunity level (line to earth) and include short-circuit, overload, over-voltage and over-temperature protection. Dimensions are (L x W x H) : HEP-240, 244.2 x 68 x 38.8mm; HEP-320, 252 x 90 x 43.8mm. These power supplies come with a 6-year warranty.
