## Long description

The EFB Elektronik NDR-120-12 is a DIN-rail mounted power supply that provides 120 W of regulated 12 V DC output for industrial and embedded applications. It accepts a universal single-phase AC input from 115 to 230 V at 47–63 Hz and is built in a compact metal housing for installation on standard TS-35 rails. The unit is designed to deliver reliable 12 V power with approximately 85.5% typical efficiency and a 16 ms hold-up time, making it suitable for control cabinets, automation devices and signage that require a stable low-voltage supply.
Advantages
The device combines a compact footprint with a metal enclosure that supports DIN-rail mounting, allowing straightforward integration into industrial control panels. Full-range input simplifies deployment across different mains voltages while built-in electromagnetic compatibility to EN55022 Class B reduces interference with nearby equipment. With a rated output power of 120 W and steady 12 V DC output, the supply provides stable voltage for connected loads and includes a standard three-year warranty for manufacturer-backed reliability.
Suitable for
 Industrial control and automation systems mounted in control cabinets
 Embedded devices and single-board computers requiring 12 V DC
