Overview

The NDR-120-12 is a slim 120W DIN-rail power supply designed for industrial control cabinets and automated systems. It provides a stable 12V DC output from a universal AC input range, featuring a 40mm wide metal housing that saves space on TS-35/7.5 or TS-35/15 rails. The unit is cooled by free air convection and includes comprehensive protection against short circuits, overloads, and overvoltage conditions.

Why Choose This Part

The slim 40mm width allows for high-density rail configurations, while the UL 508 approval ensures compliance for industrial control equipment. It features a wide operating temperature range and is built with a rugged metal case for demanding environments.

Applications

Industrial Control Systems
Supplies reliable DC power to PLCs, HMIs, and industrial controllers in factory environments.
Process Automation
Powers 12V sensors, actuators, and signal conditioners in DIN-rail mounted instrumentation cabinets.
Security and Surveillance
Provides stable power for IP cameras and access control hardware requiring 12V DC.

Getting Started

Installation is straightforward by snapping the unit onto a standard TS-35 DIN rail. Wire the AC input to the bottom terminals and adjust the output voltage between 12V and 14V using the front-panel potentiometer to compensate for cable voltage drops. Ensure at least 5mm of lateral clearance for proper convection cooling.
