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-450-5 for high-current 5V industrial electronics?

Yes, this model is intended for constant voltage 5V applications and can deliver up to 90A with a 450W rating. That makes it suitable for industrial electronics, logic systems, or other equipment built around a high-current 5V rail.

Is the HRPG-450-5 appropriate for 5V embedded systems or processor backplanes with heavy current demand?

It can be appropriate where the equipment requires a stable 5V DC source and the total load remains within 90A. Compared with lower-power 5V supplies, this model is aimed at systems that need substantially more current capacity.

Would the HRPG-450-5 fit a 5V production tester or industrial rack build?

It is a practical option for rack or enclosure-based 5V loads because it combines 450W output with a housing only 41 mm high. The 218 × 105 × 41 mm dimensions are useful where equipment density matters.

Can this 5V power supply be used in wide-temperature environments?

The published operating temperature range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve, which supports a broad range of industrial indoor conditions. Since an IP rating is not listed, the specs do not confirm direct exposure to rain, hose-down, or heavy dust.

What is the difference between the HRPG-450-5 and the other HRPG-450 models?

The HRPG-450 models are 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. This version is the 5V, 90A member of that group.
