■ Description
HEP-240 is a 240W industrial AC/DC power supply featuring the outstanding capability to operate under a
harsh environment with high dust density, humidity, vibration and altitude. The entire series is housed
with a robust aluminum case and fully potted with heat-conducted silicone. Thanks to state-of-the-art design,
the working efficiency is up to 93.5%, enabling HEP-240, with a fanless design, 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. 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.
7. 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.
8. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
9. Refer to warranty statement.
10. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude higher than 2000m(6500ft).℃℃
