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-450-36 for a 36V industrial automation system?

Yes, this model is a constant-voltage 36V power supply rated for 450W and 12.5A. That makes it appropriate for 36V automation loads that require a regulated 36V DC bus and stay within 12.5A total draw.

Is the HRP-450-36 suitable for 36V motors, actuators, or motion-control accessories?

It can be used for 36V DC equipment when the load expects constant-voltage input and the combined demand does not exceed 450W or 12.5A. Buyers should match it only to 36V hardware, since this unit does not provide 24V or 48V output.

Can this 36V power supply run a larger 36V embedded or test bench setup?

For centralized 36V DC bench or embedded power, the 450W output at up to 12.5A gives substantial headroom. It is a good fit when a 36V system needs up to 450W from a single supply.

Would the HRP-450-36 fit a 36V industrial control cabinet with wide AC input?

Yes, it accepts 85-264VAC input and delivers 36V DC in constant-voltage mode. That wide input range can simplify use across facilities with different AC mains while keeping the DC side at 36V and 12.5A maximum.

Is the HRP-450-36 suitable for outdoor or harsh-temperature environments?

The operating temperature range is -40°C to +70°C, with load derating at higher ambient temperatures per the derating curve, so check the curve before running full load in hot locations. No IP rating is provided in the specs, so indoor or outdoor exposure should be judged based on the enclosure used around the power supply rather than the unit alone.
