MEAN WELL MDR-20-15 15V 1.34A 20W DIN Rail Switching Power Supply

Description

MEAN WELL MDR-20-15 DIN Rail Power Supply

The **MEAN WELL MDR-20-15** is a single-output industrial AC-to-DC switching power supply from the MDR-20 series. It converts a compatible AC or DC input into a regulated 15V DC output for equipment that requires a stable, low-power supply. With a rated output of 20W and a maximum output current of 1.34A, it is designed for installation inside electrical cabinets and industrial control panels.

Its slim housing helps conserve DIN-rail space, while built-in protection functions and a DC OK signal support practical integration into control and monitoring systems.

Key Features of the MDR-20-15

– **15V DC output:** Provides power for equipment designed to operate at 15V DC.
– **20W rated power:** Supplies up to 1.34A within the unit’s rated output limits.
– **Universal input range:** Accepts 85–264V AC or 120–370V DC input, subject to the manufacturer’s installation instructions.
– **Compact DIN-rail design:** The 22.5mm-wide housing helps save space inside electrical enclosures.
– **Built-in protection:** Includes short-circuit, overload and overvoltage protection.
– **DC OK signal:** Supports external monitoring of the output status.
– **Natural cooling:** Uses free-air convection rather than a built-in cooling fan.
– **Low no-load consumption:** Typical no-load power consumption is below 0.75W.

Applications

The MEAN WELL MDR-20-15 may be suitable for compatible equipment such as:

– Industrial control panels and electrical cabinets
– Automation and control circuits
– Control interfaces and electronic modules
– Monitoring and signalling equipment
– Auxiliary power circuits in industrial systems
– Other devices requiring a compatible 15V DC supply within the 20W rating

Confirm the voltage, current demand, environmental conditions and equipment requirements before selecting the power supply.

Installation and Buyer Guidance

Before ordering the MDR-20-15, confirm that your equipment requires **15V DC** and draws no more than the supply’s rated 1.34A output current and 20W power. Allow for startup current, load variation and any required design margin.

Install the unit on a compatible DIN rail and follow the manufacturer’s wiring, grounding, ventilation and derating instructions. Disconnect input power before wiring or servicing, and ensure that installation is carried out by a suitably qualified person.

Do not confuse the MDR-20-15 with other MDR-20 variants, such as the MDR-20-12 or MDR-20-24, because their output voltages differ.
