Test conditions and notes10
- 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 BS EN/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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
- 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 higher than 2000m(6500ft).

FAQ
Can I use the HEP-185-36 for 36V industrial automation or motion-control equipment?
Yes, this model provides 36V constant voltage at up to 5.2A, with a total output rating of 187.2W. That makes it suitable for 36V industrial and embedded equipment designed for a fixed 36VDC supply. The wide 90-264VAC input (277VAC operational) also supports use across varied facility power conditions.
Is the HEP-185-36 appropriate for 36V LED lighting or display systems in harsh environments?
It can be used for 36V constant-voltage lighting or display loads as long as the total draw stays within 187.2W and 5.2A. Because this version is rated IP68 and operates from -55°C to +70°C (subject to the derating curve), it is positioned for harsher indoor or outdoor conditions than a standard indoor supply. The IP68 sealing also helps in dirty or wet environments.
Can the HEP-185-36 power 36V embedded electronics or industrial sensors from a single AC source?
It is intended for 36VDC loads that need a constant-voltage source and fit within 5.2A and 187.2W. The 90-264VAC input (277VAC operational) allows one model to be used across a broad AC input range. That makes it practical for 36V embedded or automation systems with consistent DC bus requirements.
Is the HEP-185-36 suitable for outdoor enclosures or exposed industrial locations?
Yes, this is the IP68 version, so it is the more sealed option in the HEP-185-36 pair. It is also rated for -55°C to +70°C operation (subject to the derating curve) and 10G vibration. Those specs make it a strong fit for exposed or demanding locations when a sealed 36V supply is needed.
How does the HEP-185-36 compare with other HEP-185 voltage variants?
In the HEP-185 family, the choices are 156W at 12V and 13A, 172W at 15V and 11.5A, 187.2W at 24V and 7.8A, 187.2W at 36V and 5.2A, 187.2W at 48V and 3.9A, and 186.3W at 54V and 3.45A. The HEP-185-36 and HEP-185-36A share the same 187.2W, 36V, and 5.2A electrical rating. The main difference is choosing the output voltage that matches the load, while this version is the IP68 model.
