Test conditions and notes7
  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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. No load power consumption<0.5W when RC- & RC+ (CN100 pin4,6) 0 ~ 0.8V or short.
  7. 7. 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 HRPG-300-36 for a 36V industrial automation load?

Yes, if the equipment requires constant voltage at 36V and the total draw stays within 9A and 324W. That makes it suitable for 36V automation or industrial DC loads that match those output limits.

Is the HRPG-300-36 suitable for embedded or OEM systems built around a 36V DC rail?

It can be used in systems that distribute 36V DC from a central supply. The important fit check is that the combined load remains at or below the rated 9A output current and 324W power.

Would this model work for a compact 36V control cabinet power section?

The 41 mm height and 199.0 x 105.0 x 41.0 mm dimensions make it practical where enclosure depth is limited. That is useful in control cabinets or machine compartments needing a 36V constant voltage source.

Can the HRPG-300-36 be used where AC input conditions vary by site?

It accepts 85-264VAC input, which supports deployment across a broad AC input range. On the DC side, it provides a fixed 36V output with up to 9A available.

Is the HRPG-300-36 suitable for outdoor use or temperature extremes?

The published operating temperature range is -40°C to +70°C, with output derating required at higher ambient temperatures according to the derating curve. No IP rating is provided in these specs, so the listing does not confirm direct outdoor exposure and it should be treated as a protected indoor or enclosure-mounted supply.

How does the HRPG-300-36 compare with the rest of the HRPG-300 family?

The listed HRPG-300 models are 198W at 3.3V and 60A, 300W at 5V and 60A, 300W at 7.5V and 40A, 324W at 12V and 27A, 330W at 15V and 22A, 336W at 24V and 14A, 324W at 36V and 9A, and 336W at 48V and 7A. This version shares the 324W class with the 12V model and delivers 36V at 9A.
