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-24 for 24V PLC systems, industrial I/O, or automation controls?

Yes, this model is built for constant voltage 24V output and is rated 336W with up to 14A. That makes it a fit for 24V industrial control systems and automation hardware designed around a 24V DC bus.

Is the HRP-300N-24 appropriate for 24V machine electronics or panel-based instrumentation?

It is appropriate when the equipment requires regulated 24V DC and the total load stays within 336W and 14A. Those specs align with many industrial electronics and instrumentation assemblies that standardize on 24V.

Can this 24V power supply run multiple 24V devices in a single enclosure?

Yes, as long as the combined 24V load does not exceed 14A or 336W. It is intended for constant voltage operation, so it works best in systems where all connected loads are designed for a 24V supply rail.

Is the HRP-300N-24 suitable for indoor factory use where temperatures can get very low or very high?

The operating temperature range is specified at -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. The provided specifications do not state an IP rating, so outdoor exposure capability is not confirmed from this data.

What is the difference between the HRP-300N-24 and the other HRP-300N models?

The HRP-300N series variants listed are 12V at 324W and 27A, 24V at 336W and 14A, 36V at 324W and 9A, and 48V at 336W and 7A. The HRP-300N-24 is the 24V option, so its key published output is 14A (336W rated) within the same 300W-class series.
