Description

Mean Well NDR-120-24 AC-DC Single output Industrial DIN rail power supply

Introduction

The NDR(NDR-120-24) Series of DIN rail power supplies is designed specifically for use in industrial applications. The 40 to 63 mm slim form-factor enables the power supplies to be easily installed in small and confined spaces such as cabinets. The broad operating temperature range of -20 to 70°C means they are capable of operating in harsh environments. The NDR Series has an AC input range from 90 VAC to 264 VAC, and conforms to the EN 61000-3-2 standard. In addition, these power supplies feature constant current mode to provide overload protection

Features
