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-450-7.5 for 7.5V industrial or embedded equipment?

Yes, if the equipment is designed for a constant 7.5V DC input and needs up to 60A. This supply delivers 450W at 7.5V, which fits specialized low-voltage industrial or embedded systems that do not run on the more common 5V, 12V, or 24V rails.

Is the HRPG-450-7.5 suitable for high-current 7.5V test benches or production fixtures?

It can be a good match for fixed 7.5V loads in manufacturing or validation setups because it provides a constant voltage output with substantial current capacity. With 60A available, it is sized for heavier 7.5V demand than smaller supplies in the same voltage class.

Would this power supply work for a custom 7.5V control assembly in a compact enclosure?

It measures 218 × 105 × 41 mm, only 41 mm high, which can help in compact cabinets or rack-adjacent assemblies. The unit also provides 450W, so it suits builds that need both 7.5V output and higher current overhead.

Is the HRPG-450-7.5 appropriate for outdoor or unsealed environments?

The operating temperature spec is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve, so it covers a broad industrial temperature range. However, there is no IP rating in the provided data, so the listing does not establish exposed outdoor suitability without a protective enclosure.

How does the HRPG-450-7.5 compare with the rest of the HRPG-450 family?

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. This model sits between the 5V and 12V versions, with 7.5V output and 60A current capacity.
