When you need a 24V 5A DIN rail power supply for an industrial control panel, two listings with the same NDR-120-24 model number may catch your eye. One is from MEAN WELL, the other from MW, and they carry different listed prices and different sets of specifications. This head-to-head review compares the two so you can decide which listing matches your project needs.
Quick Verdict
Both units are listed as new, DIN-rail-friendly 24V 5A supplies with a nominal 120W rating. The Mean Well listing provides a fuller electrical spec sheet, including agency approvals, efficiency, ripple, and regulation figures. The MW listing adds a blue housing, an indoor/outdoor installation area, and a 5A inrush current rating. If you want more technical documentation up front, the Mean Well listing is the clearer choice; if you need the environmental and color details, the MW listing provides them.
Comparison Snapshot
| Product | Listed price | Price bar | Brand | Model / MPN | Condition | Key listed details |
|---|---|---|---|---|---|---|
| Mean Well NDR-120-24 | USD 31.64 | MEAN WELL | NDR-120-24 | New | 24VDC 5A 120W, 88% efficiency, agency approvals, no PFC | |
| MW NDR-120-24 | USD 44.99 | MW | NDR-120-24 | New | Blue housing, indoor/outdoor installation, 5A inrush current |
Where Each Listing Leads
The Mean Well listing leads on technical documentation: it specifies ripple and noise (120 mV p-p), load and line regulation, input current, and a list of agency approvals (UL, CUL, TUV, CB, CE, EN, EAC). The MW listing leads on physical and environmental attributes: a blue color, an indoor/outdoor installation area, and a stated inrush current rating.
Mean Well NDR-120-24
If you want to see the full electrical picture before buying, this listing gives you a lot to work with. The output is 24 VDC at 5 A (120 W), efficiency is stated as 88%, and the protection list covers short circuit, over voltage, overload, and over temperature. It also includes agency approvals such as UL, CUL, TUV, CB, CE, EN, and EAC, along with universal AC input and a 100% full-load burn-in test. The catch: this listing notes 'Low Power Source (LPS) No' and 'No PFC Function,' so if those features are required for your application, this unit may not meet them. Still, the detailed specifications make it a strong candidate when you need to compare technical parameters.
MW NDR-120-24
The MW listing stands out for its physical and installation specs: it shows a blue housing, an indoor/outdoor installation area, and a 5A inrush current rating. It is listed as new, DIN rail mountable, and carries the same NDR-120-24 model and 120W nominal rating. If your control panel needs a power supply specified for both indoor and outdoor use, or you prefer a blue enclosure, those details are right here. The trade-off is the listed price: USD 44.99, which is higher than the other listing's USD 31.64. If budget is your primary constraint, you may want to see whether the additional attributes justify the difference.
Final Choice by Use Case
Choose the Mean Well NDR-120-24 if you want the more detailed electrical specification list. Choose the MW NDR-120-24 if you specifically need the listed indoor/outdoor installation rating, a blue housing, and the inrush current specification, and you're comfortable paying more for those details.
