Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
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. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. 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-300-36 for a 36V industrial control or automation load?

Yes, if the load is designed for 36V constant voltage and stays within 9A and 324W. This version is intended for 36V applications rather than the more common 24V or 48V control power rails.

Is the HRP-300-36 suitable for 36V embedded equipment or industrial electronics?

It can be used where the equipment requires a regulated 36V DC supply and draws no more than 9A. The 85-264VAC input also supports operation from a broad AC input range.

Would this model work for a centralized 36V DC subsystem inside a machine or cabinet?

It is a fit for centralized 36V constant voltage loads up to 324W. The 199.0 × 105.0 × 41.0 mm housing and 0.95 kg weight can also matter when space and mounting mass are limited.

Is the HRP-300-36 rated for outdoor use or only protected environments?

The operating temperature range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is stated in the provided specs, so it is better treated as an indoor or protected-enclosure unit instead of an exposed outdoor power supply.
