Details
Meanwell HEP-240-48 is a 240W industrial AC/DC power supply with 48V5A240W250mVp-p44.8-51.2V. The model features the outstanding capability to run under a harsh environment with high dust density, humidity, vibration and altitude. Moreover, HEP-240-48 is housed with a robust aluminum case and fully potted with heat-conducted silicone. Owing to state-of-the-art design, the working efficiency can go up to 93.5%, which ensures it to operate perfectly between -55℃ and +70℃ under free air convection with no fan. In addition, Meanwell HEP-240-48 supplies the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. Thanks to the high efficiency, high reliability and long longevity, Meanwell HEP-240-48 is a high performance solution for various industrial applications.
