Bisogno di aiuto?
Introduction
The NDR 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 devices have a metal housing, an AC input range from 90 VAC to 264 VAC, and conform to the EN 61000-3-2 standard. In addition, these power supplies feature constant current mode to provide overload protection.
Features and Benefits
- DIN-rail mounted power supply
- Slim form factor that is ideal for cabinet installation
- Universal AC power input
- High power conversion efficiency
