NDR-960 Din Rail AC to DC Switching Power Supply

The WEHO NDR-960 is a high-performance 960W single-phase DIN rail power supply, engineered for industrial applications demanding high reliability and efficiency. It is available in 24V and 48V output models, both featuring a high efficiency of 92% and a wide operating temperature range of -30°C to +70°C, cooled by natural convection.

Designed for durability and safety, the NDR-960 complies with international safety standards including UL508 and TUV BS EN/EN62368-1.[1] It features comprehensive protection against overload, overvoltage, and over-temperature, ensuring robust operation in harsh environments.[2] With a peak load capability of 1250W for 3 seconds, it can handle demanding start-up loads. The slim, space-saving design for TS35/7.5 or TS35/15 DIN rails makes it an ideal and dependable power solution for industrial control systems, factory automation, and other critical equipment.
