Description
HEP-480 is a 480W industrial AC/DC power supply featuring the outstanding capability to operate 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. Thanks 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.

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25
℃
of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the setup time.
5. Derating may be needed under low input voltages. Please refer to the STATIC CHARACTERISTICS for more details.
6. The power supply shall be regarded as one component of the final system. The EMC performance will be affected by the complete system installation
and/or configuration, the final system manufacturers must re-verify overall EMC directive with the complete installation and/or configuration.
7. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
