Details
Meanwell HEP-480 Series is a 480W industrial AC/DC power supply, and features the outstanding capability to run under highly humid, dusty, oily, and high-vibration harsh environment. The entire series is housed with the aluminum case and fully potted with heat-conducted silicone. As to state-of-the-art design, the working efficiency is up to 95%, enabling HEP- 480 perfectly work between -55℃ and +65℃ under free air convection. HEP-480 series Is able to meet 6KV surge immunity level and withstand 10G vibration test. Additionally, it provides the full protection functions such as Short circuit, Overload, Over voltage and Over temperature. Due to the high efficiency, high reliability and long longevity, Meanwell HEP-480 is a high performance solution for various industrial applications.
