DIN rail power supply 20W 12V 1.67A MDR-20-12

Universal DIN rail mounting power supply

The MDR-20-12 power supply is a reliable 12V DC voltage source, designed for use in automation, alarm, access control and many other applications. Mounting on a TH35 DIN rail simplifies installation and ensures stability in industrial conditions. The device is characterized by high efficiency and compact dimensions, allowing it to be used even in limited spaces.

Safety and functionality

The power supply is equipped with comprehensive protections, protecting both the unit itself and the devices connected to it. These include:

• Short-circuit protection (SCP): automatically cuts off the power supply in the event of a short circuit, preventing damage.
• Overload protection (OLP): limits power consumption, protecting against overload and overheating.
• Overvoltage protection (OVP): stabilizes the output voltage, protecting sensitive components.
• LED indication: informs about the correct operation of the power supply.

This ensures that the installation is safe and reliable. The power supply operates in a wide temperature range – from -20°C to +70°C – making it suitable for indoor and outdoor applications (in an enclosure).

Technical specifications and application

The MDR-20-12 power supply converts network voltage 85-264V AC to a stable 12V DC voltage with a maximum current of 1.67A and a power of 20W. An efficiency level of 80% minimizes energy losses and reduces operating costs. This makes it an effective solution for both professional installers and end-users looking for a reliable power supply for their devices. It is ideal for monitoring systems, intercoms, LED lighting or building automation control. Additionally, the lack of inrush current minimizes interference in the electrical network.
