Product information

Description

No name MDR-40-12 is a 40W switching power supply that delivers a regulated 12V DC output with a maximum current of 3.33A. The unit is built for DIN-rail mounting and features a compact metal/plastic enclosure suitable for installation inside electrical cabinets, distribution panels and industrial control boxes. It provides stabilized output voltage for LED lighting, CCTV systems, automation modules and other low-voltage equipment that require a steady 12V supply.

Advantages

The switching design ensures efficient AC-to-DC conversion and reduced heat generation compared with linear supplies. Integrated protections against short circuit and overload increase operational safety and help prevent damage to connected devices. The DIN-rail form factor and compact footprint simplify mounting and wiring in confined electrical enclosures. The supply provides a regulated output to support consistent performance of LEDs, cameras and control electronics under varying load conditions.

Suitable for

  • LED lighting strips, modules and drivers requiring 12V DC
  • CCTV cameras and video equipment with 12V power input
  • Industrial control modules, PLCs and sensors with low-voltage supply
  • Small network devices, relays and actuators powered from 12V

Key specifications

  • Output voltage: 12 V DC regulated
  • Maximum output current: 3.33 A
  • Rated output power: 40 W
  • Input type: AC mains switching supply
  • Mounting: DIN-rail compatible enclosure
  • Protections: short-circuit and overload protection
  • Cooling: convection (no fan)
  • Enclosure: compact design for electrical cabinets

How to use

Mount the unit on a standard DIN-rail inside an appropriate electrical cabinet or distribution panel. Connect AC mains to the input terminals following local wiring regulations and ensure correct grounding. Connect the 12V DC output to the load, observing polarity. Verify the load current does not exceed the 3.33A rating and allow adequate clearance for ventilation. If the protection mechanism activates due to overload or short circuit, remove the fault and restart power according to standard safety procedures.

Usage recommendations

Install the power supply in a dry, well-ventilated location away from direct heat sources. Keep the cumulative current of connected devices below the rated 3.33A, and use appropriate wiring and fuses on both input and output sides. Regularly inspect terminals for secure connections and follow local electrical codes for earthing and overload protection.
