Overview

What it is

The MEAN WELL NDR-120-48 is a DIN rail power supply from the SDR-120 series (120 W Single Output Industrial DIN RAIL), rated 48 V, 2.5 A, 120 W.

What it is used for

Mounts on a TS-35 DIN rail inside control or security panels to supply 48 V DC to controllers, relays, sensors and access control equipment. MEAN WELL lists applications such as industrial control systems, semiconductor fabrication equipment, factory automation, electro-mechanical apparatus.

Key features

  • Universal AC input, full range.
  • Protections: short circuit, overload, over voltage and over temperature.
  • Cooling by free air convection.
  • Mounts on DIN rail TS-35/7.5 or 15.
  • UL 508 (industrial control equipment) approved.
  • 100% full load burn-in test.

Key Specifications

  • Output Voltage: 48 V.
  • Rated Output Current: 2.5 A.
  • Rated Output Power: 120 W.
  • Input Voltage Range: 90 to 264 V AC or 127 to 370 V DC.
  • Efficiency (typ.): 89%.
  • Operating Temperature: -20 to +70 °C (refer to derating curve).

Buying considerations

Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
