Product information

Description

The MEAN WELL MDR-20-12 20W Blue White is a compact DIN-rail power supply designed for control cabinets and industrial equipment that require a stable 12V DC source. It accepts a wide AC input range from 85 to 264V and operates across 47–63Hz, delivering up to 20 watts with passive cooling and an LED power indicator for visual status. The unit is certified to recognized safety standards and offers a high mean time between failures, making it suitable where continuous, low-maintenance power is needed.

Advantages

The unit’s slim 22.5 mm width saves space in crowded enclosures while the 100 mm depth and 90 mm height provide a low-profile footprint. Passive cooling eliminates moving parts and reduces maintenance and noise. The wide input voltage range allows use in diverse supply environments, and the LED indicator gives immediate feedback about power presence. Safety approvals support integration into industrial and commercial systems where certified components are required.

  • DIN-rail mounted control cabinets and automation panels
  • Industrial sensors, relays and PLC auxiliary power
  • Building management and access control systems
  • Small instrumentation and measurement devices requiring 12V DC

  • Input voltage range: 85–264 V AC
  • Input frequency: 47–63 Hz
  • Cooling method: passive (convection)
  • LED status indicator: power ON
  • Certifications: UL508, TUV EN60950-1
  • MTBF: 236,900 hours
  • Mounting: DIN-rail
  • Housing color: blue/white
  • Dimensions (W × D × H): 22.5 mm × 100 mm × 90 mm

How to use

Mount the power supply securely on a standard DIN-rail inside the control cabinet, ensuring adequate space around the unit for convection cooling. Connect AC input conductors to the designated terminals following local wiring regulations and verify correct grounding. Connect the 12V DC output to the load, observing polarity. Power up the AC supply and confirm the LED indicator to ensure the unit is delivering output. Perform functional checks of connected devices to verify correct operation.

Usage recommendations

Place the unit in an environment within the manufacturer’s specified temperature and humidity limits, avoid obstructing airflow around the housing, and protect the supply from excessive vibration and conductive dust. For installations with significant ripple or noise sensitivity, add appropriate filtering or transient suppression at the load side. When deploying in critical systems, consider redundancy or periodic inspection to ensure long-term reliability.
