Details
Meanwell HEP-320-48 is a 320W industrial AC/DC power supply with 48V6.7A321.6W250mVp-p43-52V3.35-6.7A. This model features the powerful capability to work under harsh conditions with high dust density, humidity, vibration and altitude. Besides them, HEP-320-48 is housed with a robust aluminum case and fully potted with heat-conducted silicone. Because of the state-of-the-art design, its working efficiency could reach up to 95%, which enables it to run perfectly between -55℃ and +70 ℃ under free air convection with no fan. Additionally, HEP-320-48 provides the full protection functions such as Short circuit, Overload, Over voltage and Over temperature. As a result of the high efficiency, high reliability and long longevity, Meanwell HEP-320-48 is a high performance solution for various industrial applications.
