Product information

Description

The MEAN WELL RSP-320-48 is a compact, 321.6 W switching power supply in a 1U metal housing designed for industrial and IT applications. It accepts a universal AC input (88–264 V, 47–63 Hz) and delivers a 48 V DC output with active PFC and forced-air cooling via a single fan. The unit measures 115 mm × 215 mm × 30 mm and includes safety approvals (UL60950-1, TUV EN60950-1, CCC GB4943) and an LED power-on indicator.

Advantages

The power supply features built-in active power factor correction with PF > 0.95 and high conversion efficiency up to 90%, reducing energy loss and heat generation. Its low-profile 1U (30 mm) metal case supports space-constrained installations. The design offers long-term reliability with an MTBF of 206,500 hours and optional conformal coating for improved protection in harsh environments.
