Details
Meanwell HEP-320-12 is a 320W industrial AC/DC power supply with 12V22A264W150mVp-p10.8-13.5V11-22A. this model features the outstanding capability to operate under a harsh environment with high dust density, humidity, vibration and altitude. In addition, HEP-320-12 is housed with a robust aluminum case and fully potted with heat-conducted silicone. Thanks to the state-of-the-art design, the working efficiency can reach up to 95%, which enables it to work perfectly between -55℃ and +70 ℃ under free air convection with no fan. Furthermore, It provides the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. In light of the high efficiency, high reliability and long longevity, Meanwell HEP-320-12 serves as a high performance solution for various industrial applications.
