Mean Well HRP-300N3-48 Power Supply 336W 48V, 350% peak power model 7A

The HRP-300N3-48 is a 48V enclosed AC-DC power supply rated at 300W with 7A rated current. The product title also identifies it as a 336W 48V model, so buyers should confirm the exact operating margin they need against the official datasheet and application load profile.

This model is aimed at industrial and high-reliability applications that need a regulated 48V DC output in a compact enclosed format. Its protection functions, DC OK signal, remote sense function, vibration resistance, and low 41mm profile make it relevant for demanding equipment where uptime and monitoring matter.

Yes. The HRP-300N3-48 supports output voltage adjustment of approximately ±15% on average, which can help when a system requires some voltage trimming around the nominal 48V output. Buyers should still confirm that the required operating voltage remains within the acceptable range for their equipment.

This power supply supports universal input across 85 to 264VAC and also accepts 120 to 370VDC. It is designed for full-range input and can withstand a 300VAC surge input for 5 seconds.

The HRP-300N3-48 is specified for operation from -40°C to +70°C and for altitudes up to 5000 meters. It also withstands 5G vibration and includes an internal cooling fan with ON-OFF control, which supports use in tougher industrial environments.

This model includes protection for short circuit, overload, over voltage, and over temperature. It is approved to UL62368-1, TUV BS EN/EN62368-1, EAC TP TC 004, and AS/NZS 62368.1, and it meets listed EMC standards including EN55022 Class B and EN61000-6-2 heavy industry level.
