Test conditions and notes10
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltages. Please check the static characteristics for more details.
  5. 5. A type only.
  6. 6. Safety and EMC design refer to BS EN/EN60598-1, CNS15233, GB7000.1, FCC part18.
  7. 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. 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. 9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
  10. 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 the HEP-100-36A power a 36V embedded controller or industrial computer?

Yes, if the equipment is designed for 36V DC input and draws no more than 2.65A or 95.4W. This is a constant-voltage model, so it is intended for loads that expect a regulated 36V supply.

Is this a good fit for 36V motors or motion devices in automation equipment?

It may fit lower-power 36V DC motion hardware only if the total steady load remains within 95.4W and 2.65A. Buyers should match the device's required 36V input and confirm the current demand does not exceed the supply's output rating.

Can I use the HEP-100-36A for 36V communication or monitoring equipment in a plant?

Yes, if that equipment requires 36V constant voltage and stays under 95.4W. The 10G vibration tolerance and operating range of -55°C to +70°C (with derating per the derating curve) make it suitable for industrial environments.

Is the HEP-100-36A suitable for outdoor installations?

The HEP-100-36A is rated IP65 water-resistant, so it is better suited to indoor use or protected outdoor locations than the IP68 version. Its 10G vibration rating and -55°C to +70°C temperature range still make it appropriate for demanding environments.

What is the difference between the HEP-100-36A and other HEP-100 models?

The HEP-100 line includes 12V at 100.08W and 8.34A, 15V at 100.05W and 6.67A, 24V at 96W and 4A, 36V at 95.4W and 2.65A, 48V at 96W and 2A, and 54V at 95.58W and 1.77A. The HEP-100-36A matches the HEP-100-36 electrically at 95.4W, 36V, and 2.65A.
