Choosing a DIN rail power supply isn't just about finding something that outputs 24 volts. You need to match the current, the power budget, the physical format, and the price to the cabinet you're building. When you're working through the options in industrial power supplies transformers, the first decision is usually the DC output you need.
Quick verdict
If you're putting together a control cabinet and need a new 24VDC supply for small equipment, the Mean Well EDR-120-24 is a practical option. It is a 120W unit that outputs 5A at 24VDC, accepts 100-240VAC input, and mounts on a DIN rail. For $28.00, the EDR-120-24 gives you a single new unit from Mean Well.
Who it suits
The EDR-120-24 suits small automation panels, sensors, controls, or any load that stays under 5A at 24VDC. The 100-240VAC input makes it easy to use in locations with standard line voltage. It is also a good choice for a spare or replacement when the current supply in your DIN rail cabinet fails. If you are building a new cabinet, the compact DIN rail format gives you a clean way to power several low-draw devices without taking up much space.
What stands out
The headline specs are clear: 24VDC output, 5A current, 120W total power, and 100-240VAC input. That combination covers a typical range of small control loads. The DIN rail format means the EDR-120-24 clips into the standard rail used in industrial enclosures, which simplifies mounting and leaves more room for wiring. The unit is specified as new, and the model number matches the Mean Well EDR-120-24 series.
Mean Well EDR-120-24 DIN Rail Power Supply
This single DIN rail supply provides a 24VDC output at 5A for a total of 120W, with an input range of 100-240VAC. The model number EDR-120-24 appears on the unit, and the condition is new. The $28.00 price applies to one supply.
Meaningful trade-offs
The main trade-off is the 5A ceiling. If your cabinet has devices that collectively draw more than 5A at 24VDC, you will need a higher-current supply. This purchase covers one unit only, so if you are stocking multiple cabinets or want an extra on the shelf, each supply needs to be bought separately. The 100-240VAC input is flexible, but make sure the output matches your load's voltage and amperage before connecting it.
Bottom line
For a compact control cabinet with a modest 24VDC load, the Mean Well EDR-120-24 is a solid choice. It delivers the voltage and current that small automation equipment typically needs, fits the DIN rail format, and the $28.00 price makes it easy to budget for a single-unit replacement.
