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 ambient temperature derating of 3.5
/1000m is needed for operating altitude greater than 2000m(6500ft).
10. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for
1 month.|||**HEP-185-12**|**HEP-185-15**|**HEP-185-24**|**HEP-185-36**|**HEP-185-48**|**HEP-185-54**|
