Test conditions and notes8
  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. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
  7. 7. No load power consumption<0.5W when RC- & RC+ (CN100 pin1,2) 0 ~ 0.8V or short.
  8. 8. 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-450-36 for 36V industrial automation equipment?

Yes, if the equipment requires a constant 36V DC input and stays within 12.5A. This model delivers 450W at 36V, which suits automation and industrial devices built around a 36V bus.

Is the HRPG-450-36 suitable for 36V motor control or actuator systems that need a fixed DC supply?

It can be used where the system is specified for a constant voltage 36V source and the total draw does not exceed 12.5A or 450W. Buyers should match it to equipment that explicitly calls for 36V input rather than a lower-voltage supply.

Would this model work for 36V control cabinets or industrial test stations?

It is a practical option for enclosed control or test equipment that runs on a 36V rail, because it provides 450W in a 41 mm high housing. The 218 × 105 × 41 mm size can also help when panel or rack space is limited.

Can the HRPG-450-36 be used in cold or hot industrial locations?

The operating temperature range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve, so cold-start and hot locations are covered within that range. Since no IP rating is provided, the listing does not establish direct outdoor or exposed-enclosure suitability on its own.

What are the differences between the HRPG-450-36 and the other HRPG-450 power supplies?

The HRPG-450 family includes HRPG-450-3.3 at 297W, 3.3V, 90A; HRPG-450-5 at 450W, 5V, 90A; HRPG-450-7.5 at 450W, 7.5V, 60A; HRPG-450-12 at 450W, 12V, 37.5A; HRPG-450-15 at 450W, 15V, 30A; HRPG-450-24 at 451.2W, 24V, 18.8A; HRPG-450-36 at 450W, 36V, 12.5A; and HRPG-450-48 at 456W, 48V, 9.5A. The series is differentiated by output voltage and current, with small differences in rated wattage between some models.
