MEAN WELL RSP-320-36 320.4W 1U Low Profile Enclosed Power Supply 36V 8.9A

The MEAN WELL RSP-320-36 stands out in the 1U power supply class by combining a full 320.4W output with a slim 30mm profile and active PFC, making it a rare choice for high-density industrial and IT installations where space and efficiency are equally critical. Unlike many enclosed supplies that derate above 50°C, this unit delivers full power up to 50°C and only linearly derates to 50% at 70°C, ensuring reliable operation in demanding thermal environments.

Highlights

• 320.4W continuous output at 36V DC, 8.9A
• 1U low profile (30mm height) for rack and cabinet integration
• Active PFC with >0.95 at 230VAC, compliant with EN61000-3-2
• Wide input range 90–264VAC or 127–370VDC
• High efficiency up to 90%, reducing energy costs and heat
• Built-in remote sense function to compensate voltage drop
• Protections: short circuit, overload, over voltage, over temperature
• Free air convection cooling – no fan, silent operation
• Operating temperature -30°C to +70°C
• Safety approvals: UL62368-1, TUV EN62368-1, EAC TP TC 004

In daily use

Engineered for continuous duty in industrial automation, test equipment, LED signage, and communication systems, the RSP-320-36 maintains a stable 36V rail even under fluctuating mains conditions. The remote sense function ensures precise voltage at the load, while the low no-load consumption (<0.75W) meets modern standby power regulations. With a MTBF exceeding 200,000 hours and a 3-year warranty, this power supply is built for long-term deployment.
