MEAN WELL HEP-150 Switching Power Supply for Harsh Environment User Guide

HEP-150 is a 150W 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 94%, enabling HEP-150 perfectly work between -55C and +70C under free air convection.

Note:

All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25C of ambient temperature.

Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance: includes set up tolerance, line regulation and load regulation.

Derating may be needed under low input voltages. Please check the static characteristics for more details.
A type only.

Safety and EMC design refer to BS ENEN60598-1, CNS15233, GB7000.1, FCC part18.
Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.

The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-quality EMC Directive on the complete installation again.
The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.

The ambient temperature derating of 3.5 C /1000m with fanless models and of 5C/1000m with fan models for operating altitude higher than 2000m(6500ft).
