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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 5. 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 )
- 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-300N-12 for 12V industrial automation panels or control cabinets?
Yes, if the system requires a constant 12V supply. This model is rated 324W at 12V with up to 27A, which is appropriate for higher-current 12V control and automation loads within that rating.
Is the HRP-300N-12 suitable for powering 12V embedded systems, IPC accessories, or DC monitoring equipment?
It is suitable for 12V DC loads that need a regulated constant voltage source and stay within 324W and 27A. That profile fits many embedded and industrial electronic assemblies built around a 12V bus.
Can this model support distributed 12V sensors, relays, and low-voltage devices in one system?
It can support multiple 12V loads when the combined demand remains within 27A and 324W. For multi-device systems, the important match is a shared 12V constant voltage requirement across the connected equipment.
Does the HRP-300N-12 work in harsh indoor temperature conditions?
The specified operating temperature range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is listed in the provided specifications, so exposure resistance for outdoor conditions is not defined here.
How does the HRP-300N-12 compare with the other HRP-300N voltage models?
Within the HRP-300N family, the listed models are 12V at 324W and 27A, 24V at 336W and 14A, 36V at 324W and 9A, and 48V at 336W and 7A. The family keeps the same 300W-class platform while changing the output voltage and corresponding output current.
