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-300-24 for a 24V PLC or industrial automation system?

Yes, this model is a constant voltage 24V power supply rated for 14A and 336W. It is suited to 24V industrial and automation loads whose total demand stays within that rating.

Is the HRP-300-24 a fit for 24V embedded control equipment or instrumentation?

It can be used where the equipment requires a regulated 24V DC source and the total load remains within 14A and 336W. The 85-264VAC input range also supports use across varied AC input conditions.

Can this power supply support a 24V DC control panel with multiple devices on one supply?

It can, as long as the combined 24V demand stays within 336W and 14A. That makes it useful for centralized 24V control power in industrial panels and automation assemblies.

Would the HRP-300-24 work for a 24V communications or industrial electronics load?

It is appropriate for 24V constant voltage electronics that need up to 14A. Buyers usually choose this version when the load is specifically 24V and fits within its 336W rating.

Can the HRP-300-24 be used outdoors or in unprotected areas?

The specified operating range is -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is provided, so it should be treated as an indoor or enclosure-protected power supply rather than an exposed outdoor unit.

What are the main differences between the HRP-300-24 and the other HRP-300 versions?

The HRP-300 family includes 3.3V at 198W and 60A, 5V at 300W and 60A, 7.5V at 300W and 40A, 12V at 324W and 27A, 15V at 330W and 22A, 24V at 336W and 14A, 36V at 324W and 9A, and 48V at 336W and 7A. The HRP-300-24 sits in the middle of the voltage range while keeping the same 199.0 × 105.0 × 41.0 mm form factor and 0.95 kg weight as the other products listed here.
