■ Description

HEP-185 is a 185W 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-185 perfectly work between -55 and +70 under free
air convection.

PACKING

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

5. A type only.

6. Safety and EMC design refer to EN60598-1, CNS15233, GB7000.1, FCC part18.

7. 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.

8. 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-qualify EMC Directive on the complete installation again.

9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.

10. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude℃℃
