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 ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
6. 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 )

FAQ

What are the main output specs of the Mean Well HRP-300N3-12?

The HRP-300N3-12 is a 12V enclosed AC/DC power supply rated at 27A. Its rated output power is 324W, within the 300W-class HRP-300N3 series. It also includes an output voltage adjustment range of approximately plus or minus 15% (10.2 to 13.8V).

What kinds of applications is the HRP-300N3-12 suited for?

This model is aimed at industrial and high-reliability applications that need a compact enclosed 12V power supply. Its low 41mm profile, DC OK signal, remote sense function, and protection features make it relevant for equipment builders and OEM use. It is best evaluated where dependable 12V output and industrial compliance matter.

What input range does the HRP-300N3-12 support?

The HRP-300N3-12 supports a universal input range of 85 to 264VAC and 120 to 370VDC. The datasheet notes that output derating may be needed at low input voltages. This gives buyers flexibility across a wide range of global power environments.

Is the HRP-300N3-12 suitable for demanding industrial environments?

Yes. The published specifications list an operating temperature range of -40 to +70 degrees C (refer to the derating curve), vibration resistance up to 5G, and operating altitude up to 5000 meters. It also meets BS EN/EN61000-6-2 EMC immunity and includes overload, over voltage, and over temperature protection.

How compact is the Mean Well HRP-300N3-12?

This power supply measures 199 x 105 x 41 mm and weighs 0.9 kg. Its low-profile 41 mm height is a key differentiator for space-constrained industrial equipment. That makes it easier to specify where enclosure height is limited.

What approvals and warranty does the HRP-300N3-12 include?

The HRP-300N3-12 is listed with UL62368-1, TUV BS EN/EN62368-1, EAC TP TC 004, and AS/NZS 62368.1 safety approvals. EMC compliance includes BS EN/EN55032 Class B and EN61000 series standards, including EN61000-6-2. The datasheet does not state a warranty period, so please confirm warranty terms with the seller.
