MEAN WELL RSP-320-15 321W 1U Low Profile Enclosed Power Supply with Active PFC

Engineered for high-density industrial and networking environments, the MEAN WELL RSP-320-15 delivers 321.6W of clean, stable 15V DC power in a slim 1U profile. Unlike generic open-frame supplies, this enclosed unit features active power factor correction, remote ON/OFF control, and a speed-controlled fan for quiet, reliable operation under varying loads.

Highlights

• High efficiency up to 89% and active PFC (>0.95) reduce energy waste and harmonic distortion
• Wide input range 85~264VAC (120~370VDC) for global compatibility
• Built-in DC fan with automatic speed control balances cooling and noise
• Comprehensive protections: short circuit, overload, over voltage, over temperature
• Remote sense and remote ON/OFF for system integration
• Low profile 30mm height fits 1U rack-mount chassis

In daily use

The RSP-320-15 excels in automation, test equipment, LED signage, and telecom applications where space is limited but power demands are high. Its robust metal enclosure and 3kVAC isolation ensure safety and longevity. The unit operates from -30°C to +70°C, with full power up to 50°C and linear derating beyond. Ripple and noise are held to 150mVp-p, making it suitable for sensitive electronics.
