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 key output specifications of the Mean Well HRP-300N3-24?

The HRP-300N3-24 is a 24V enclosed AC-DC power supply rated at 336W continuous output. It provides 14A rated current and has an output voltage adjustment range of 21.6 to 28.8V. This model is designed for applications that need a compact 41mm low-profile power supply.

What makes the HRP-300N3-24 suitable for demanding industrial applications?

This model is built for high-reliability industrial use with protections for overload, over voltage, and over temperature. It also operates from -40°C to +70°C with derating, withstands 5G vibration, and includes a built-in DC OK signal. These features help it perform well in tougher operating environments.

What input voltage range does the HRP-300N3-24 support?

The HRP-300N3-24 accepts a universal AC input range of 85 to 264VAC, as well as 120 to 370VDC. That wide input range makes it suitable for use across many regional power systems and industrial DC supply environments. It is intended for applications where input flexibility is important.

Can the HRP-300N3-24 operate in high-temperature or high-altitude environments?

Yes, this model is rated for operation from -40°C to +70°C when used within its derating limits. It is also specified for operating altitudes up to 5000 meters. Those ratings make it a strong fit for industrial environments with harsher temperature or elevation requirements.

How compact is the Mean Well HRP-300N3-24?

The HRP-300N3-24 measures 199 x 105 x 41 mm and weighs approximately 0.9 kg. Its 41 mm height gives it a low-profile form factor, which is useful where installation space is limited. This makes it easier to specify in compact industrial enclosures and equipment.

How does the HRP-300N3-24 differ from a basic 24V power supply?

Compared with a basic enclosed 24V supply, the HRP-300N3-24 adds features aimed at higher reliability and tougher industrial use. These include peak power capability, remote sense, a DC OK signal, fan ON-OFF control, wide operating temperature range, and BS EN/EN61000-6-2 EMC immunity. It is better suited to applications where power quality, monitoring, and durability matter.

What certifications and compliance standards does the HRP-300N3-24 meet?

This model is approved to UL62368-1, TUV BS EN/EN62368-1, EAC TP TC 004, and AS/NZS 62368.1 safety standards. For EMC, it meets BS EN/EN55032 Class B and EN61000 series requirements, including EN61000-6-2. These approvals are relevant for many commercial and industrial equipment applications.
