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

Yes, this unit provides constant 5V output at up to 90A with 450W total power. That makes it suitable for 5V systems that need very high current capacity from a single supply.

Is the HRP-450-5 appropriate for 5V embedded controllers, logic hardware, or test fixtures?

It is appropriate when the hardware requires a regulated 5V DC source and the total draw stays within 90A and 450W. It is intended for constant-voltage 5V applications, not loads that need 12V, 24V, 36V, or 48V.

Can this model power a larger 5V bus with multiple loads?

Yes, the available 90A output makes it useful for centralized 5V distribution where several 5V loads share one source, as long as the combined draw stays within 90A and 450W.

Would the HRP-450-5 make sense for 5V industrial or IT racks with varying AC input?

It accepts 85-264VAC input and converts that to constant 5V DC. That wide AC input range is useful when the same 5V supply may be deployed across sites with different mains conditions.

Is the HRP-450-5 rated for outdoor use or harsh ambient temperatures?

The published operating temperature is -40°C to +70°C, with load derating at higher ambient temperatures per the derating curve. No IP rating is listed in the supplied specs, so exposed outdoor use should not be assumed without an external enclosure providing the needed protection.
