A. Product Overview
The Mean Well MDR-60-24 24V 2.5A 60W DIN Rail SMPS is part of the MDR-60 series of industrial power supplies. It is designed for installation on standard TS35/7.5 or TS35/15 DIN rails, making it suitable for compact electrical panels and industrial control cabinets.
The MDR-60-24 provides:
Output Voltage: 24V DC
Rated Current: 2.5A
Rated Power: 60W
Adjustable Output Voltage: 24 to 30V DC
Input Voltage: 85 to 264V AC or 120 to 370V DC
Input Frequency: 47 to 63Hz
Typical Efficiency: 87 percent
Operating Temperature: minus 20°C to 70°C, subject to derating
Dimensions: 40 × 90 × 100 mm

DC OK Output: Relay contact rated up to 30V, 1A resistive load
Its compact construction and DIN rail mounting make the MDR-60-24 particularly useful where reliable 24V DC power is required inside industrial electrical and automation panels.
B. Working Principle
The Mean Well MDR-60-24 works as a switched mode AC to DC power supply.
According to the block diagram on page 2 of the datasheet, incoming power first passes through an EMI filter. The input is then rectified and filtered before being processed by a high frequency power switching circuit. The converted energy passes through isolation and is rectified and filtered again to produce the regulated DC output.
A feedback and control circuit continuously monitors the output. Protection circuits are integrated for overload, overcurrent, and overvoltage conditions. The supply also includes a DC OK relay contact that indicates whether the power supply is operating normally.
When the power supply is operating correctly, the DC OK relay contact closes. When the power supply switches off or DC output fails, the contact opens.
This design allows the MDR-60-24 to deliver a regulated 24V DC supply even when the incoming AC voltage varies within its permitted range.
C. Why Mean Well MDR-60-24 Is Used
The MDR-60-24 is used when industrial equipment requires a dependable 24V DC power source from mains AC power.
It is particularly useful because it combines a wide input range, compact DIN rail construction, 60W output capacity, adjustable voltage, passive cooling, protection functions, and a DC OK status relay in one device.
The datasheet specifies protection against short circuit, overload, and overvoltage. Overload protection operates at approximately 105 to 150 percent of rated output power and automatically recovers after the fault is removed.
The MDR-60 series is also designed for free air convection cooling, so an additional cooling fan is generally not required under normal specified operating conditions.
Typical applications can therefore include PLC panels, industrial control systems, process automation panels, relay circuits, sensors, transmitters, industrial instrumentation, building automation systems, access control systems, machine control panels, and other equipment operating from 24V DC.
These application examples are based on the electrical characteristics and DIN rail industrial design of the product rather than being an exhaustive application list stated by the manufacturer.
D. Suitable Buyers
The Mean Well MDR-60-24 24V 2.5A 60W DIN Rail Power Supply is suitable for buyers who require a compact and reliable industrial 24V DC power supply.
Typical buyers can include industrial automation companies, electrical panel manufacturers, machine builders, system integrators, PLC control panel manufacturers, instrumentation companies, OEM manufacturers, maintenance departments, process automation companies, building automation contractors, industrial equipment manufacturers, electrical engineers, control engineers, and industrial spare parts suppliers.
It is especially relevant for systems where the total connected 24V DC load remains within the power supply's 2.5A and 60W rated capacity.
