MEAN WELL Τροφοδοτικό Ράγας DIN NDR-120-48 48V/120W/2.5A

The MEAN WELL NDR-120-48 is a high-efficiency DIN rail switching power supply delivering 48V DC at 2.5A (120W). Designed for industrial control cabinets, it features a compact metal case, free air convection cooling, and a wide operating temperature range from -20 to +70°C. With protections against overload, over voltage, and short circuit, it ensures reliable power for automation systems, security equipment, and telecom devices.

Advantages

High efficiency up to 89% reduces energy loss and heat generation. Universal AC input (90-264VAC) allows global use. The slim 32mm width saves space on DIN rails. Built-in constant current limiting for overload protection and auto-recovery hiccup mode for short circuits enhance system safety.
