Details
Meanwell MDR-20-12 is an ultra-thin single-output DIN rail power supply with 12V1.67A0-1.67A20W120mVp-p10.8-13.2V. The model can be installed on DIN rail TS-35/7.5 or TS-35/15, and cooled by natural air convection and also with Built-in active DC OK signal. As the flexible DIN rail mounting system can increase the installation speed, all equipment can be easily snapped into the metal rail. At the same time, Meanwell MDR-20-12 could be easily arranged on the DIN rail using a closed junction box or in a location with limited space. Similar devices can be installed in close proximity to each other, thus reducing the wiring required. MDR-20-12 offers short-circuit, overload and over-voltage protection. In addition, Most power supplies are convectively cooled, so no cooling fans are required. Due to these points, Meanwell MDR-20-12 is widely applied in a variety of automation, instrumentation and industrial applications such as power various DC operating equipment including sensors, motors, actuators, solenoid valves and relays.
