TDR-960-48 Power Supply 340-550VAC 3 phase input, output 48 volts DC 20.0 Amps

Why Choose the MEAN WELL TDR-960-48 DIN Rail Power Supply?

The MEAN WELL TDR-960-48 is a high-performance 960 W three-phase industrial DIN rail power supply designed to provide a stable 48 V DC output at 20 A for demanding industrial automation, control and electrical systems. As part of the MEAN WELL TDR-960 series, it combines a wide three-phase AC input range, high efficiency and a compact metal enclosure for reliable operation inside industrial control panels.

Designed for three-phase industrial power systems, the TDR-960-48 accepts a wide 340–550 V AC input and incorporates active Power Factor Correction (PFC). Its efficiency reaches up to 94.5%, helping reduce power losses and heat generation, while free-air convection cooling eliminates the need for an internal cooling fan.

With a rated output of 48 V DC, 20 A and 960 W, the TDR-960-48 is well suited to powering industrial automation equipment, control systems, communications equipment, machinery and other high-power DC loads. Its slim 110 mm-wide design mounts directly onto standard TS-35 DIN rail, making efficient use of valuable control cabinet space.
