Moxa NDR-120-24 NDR DIN-rail Power Supply

Introduction

Moxa NDR-120-24 DIN rail power supply are particularly intended for industrial applications. The power supply' tiny form factor of 40 to 63 mm allows for easy installation in small and constrained locations such as cabinets. They can operate in severe settings because to their wide working temperature range of -20°C to 70°C. The devices feature a metal casing, an AC input range of 90 VAC to 264 VAC, and comply with the EN 61000-3-2 standard. In addition, these power supply provide a constant current mode for overload prevention.

Features and Benefits

Features include a DIN-rail mounted power supply, a slim form factor for cabinet installation, universal AC power input, and high conversion efficiency.
