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 I use the HEP-185-15A for 15V industrial electronics or automation hardware?

Yes, it is a constant-voltage 15V power supply rated for 172W and 11.5A. It is intended for 15V DC equipment that stays within those power and current limits.

Is the HEP-185-15A a fit for 15V control cabinets or factory monitoring equipment?

It can be used in industrial cabinets or monitoring systems that require 15V DC up to 172W and 11.5A. The IP65 rating and 10G vibration resistance are useful in environments where reliability and low maintenance matter.

Can this model handle 15V loads in vibration-prone equipment?

Yes, the unit is specified to withstand 10G vibration, which supports use in demanding industrial environments. Its operating range of -55°C to +70°C (subject to the derating curve) also helps where ambient conditions are severe.

Is the HEP-185-15A suitable for indoor or outdoor use?

This version is rated IP65 water-resistant, so it is suitable for indoor use and outdoor use where IP65 protection is appropriate. It also operates from -55°C to +70°C, subject to the derating curve.

What are the differences between the HEP-185-15A and other 15V HEP models?

On this sheet, the HEP-185-15 and HEP-185-15A are both rated 172W at 11.5A; the HEP-185-15 is the IP68 version and this 15A version is IP65 water-resistant. The other HEP-185 outputs are 156W at 12V, 187.2W at 24V, 36V and 48V, and 186.3W at 54V.
