MEAN WELL NDR-120-48 48V 2.5A 120W DIN Rail Power Supply

Description

Product Overview

The MEAN WELL NDR-120-48 is engineered for demanding industrial and laboratory settings where dependable power is non‑negotiable. Housed in a rugged DIN‑rail compatible enclosure, this unit measures just 2.56 x 5.91 x 5.51 inches, making it easy to integrate into tight panel spaces while still delivering a robust 120 W of output. Its primary output voltage of 48 V DC is maintained with tight regulation, ensuring that sensitive equipment receives consistent power without fluctuation.

Designed with a wide input voltage range of 90‑264 VAC and an input frequency tolerance of 47‑63 Hz, the NDR‑120‑48 can operate from standard single‑phase mains to international power grids without the need for additional transformers or converters. The unit incorporates multiple protection mechanisms, including over‑voltage, over‑current, short‑circuit, and over‑temperature safeguards, which collectively extend the lifespan of both the power supply and the downstream devices it serves.

Usage

In industrial automation, the NDR‑120‑48 powers programmable logic controllers (PLCs), motor drives, and sensor arrays that require a stable 48 V rail. Its compact DIN‑rail form factor allows for seamless mounting within control cabinets, reducing wiring complexity and freeing up valuable space for additional components. The wide input voltage tolerance also makes it suitable for field installations where power quality may vary.

Laboratory environments benefit from the unit’s low noise and high efficiency, providing clean power to analytical instruments, spectrometers, and test rigs. Researchers can rely on the NDR‑120‑48 to maintain precise voltage levels, which is critical for experiments that demand repeatable and accurate results. The built‑in protections further ensure that expensive laboratory equipment is shielded from power anomalies.

Because the power supply is rated for continuous operation at 2.5 A, it can support multiple devices simultaneously, making it an ideal choice for modular test stations or distributed sensor networks. Its robust construction also tolerates harsh temperature ranges, allowing deployment in both climate‑controlled facilities and more extreme industrial settings.
