Details

Meanwell HEP-185-48 is a 185W industrial AC/DC power supply with 48V3.9A187.2W200mVp-p43-53V1.95-3.9A±1.0%±0.5%±0.5%. The product highlights the excellent capability to operate under highly humid, dusty, oily, and high-vibration harsh environments. As it is housed with the aluminum case and fully potted with heat-conducted silicone, HEP-185-48 is able to meet 6KV surge immunity level, withstand 10G vibration test and operate up to 5000 meters. Apart from them, the item supplies the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. Based on the state-of-the-art design and built-in active PFC function, the working efficiency could reach up to 94%, enabling HEP-185-48 perfectly work between -55 ℃ and +70 ℃ under free air convection. Because of its high reliability, excellent quality and long life, Meanwell HEP-185-48 is ideal to be applied for critical conditions.
