Mean Well HRP-300N3-24 Power Supply 336W 24V, 350% peak power model 14A

The HRP-300N3-24 is a 24V enclosed AC-DC power supply rated at 300W continuous output. It provides 14A rated current and has an output voltage adjustment range of approximately ±15% from nominal. This model is designed for applications that need a compact 1U low-profile power supply.

This model is built for high-reliability industrial use with protections for short circuit, overload, over voltage, and over temperature. It also supports 300VAC surge input for 5 seconds, withstands 5G vibration, and includes a built-in DC OK signal. These features help it perform well in tougher operating environments.

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.

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.

The HRP-300N3-24 measures 199 x 105 x 41 mm and weighs approximately 0.9 kg. Its 41 mm height gives it a 1U low-profile form factor, which is useful where installation space is limited. This makes it easier to specify in compact industrial enclosures and equipment racks.

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 heavy-industry EMC performance. It is better suited to applications where power quality, monitoring, and durability matter.

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 EN55022 Class B and EN61000 series requirements, including heavy industry level EN61000-6-2. These approvals are relevant for many commercial and industrial equipment applications.

The Mean Well HRP-300N3-24 includes a 5-year warranty. That extended warranty aligns with its positioning as a high-reliability industrial power supply. It can be an important consideration for buyers evaluating long-term support and lifecycle cost.
