If you're wiring a small control cabinet, the power supply decision usually comes down to output voltage and available current. Four new DIN rail supplies in this rundown split into two groups: one 12V/10A unit and three 24V/5A units. The 12V option covers lower-voltage sensors and controls, while the 24V group handles the far more common industrial logic voltage.
Quick take
- The 12V/10A NDR-120-12 is the only supply here for 12V circuits.
- The cheapest 24V/5A unit is also the only one with a stated 100-240V input range and efficiency figure.
- The two NDR-120-24 entries share the same output spec and indoor/outdoor installation area, so they are hard to separate on paper.
Listed price comparison
| Product | Output | Current | Listed price | Price bar |
|---|---|---|---|---|
| 120W 24VDC 5Amp Single Output DIN Rail Supply | 24V DC | 5A | $22.99 | |
| NDR-120-12 10A 12V DIN Rail Supply | 12V DC | 10A | $39.99 | |
| NEW NDR-120-24 24V 5A DIN Rail Supply | 24V DC | 5A | $44.99 | |
| 5A NDR-120-24 24V 5A NEW DIN Rail Supply | 24V DC | 5A | $44.99 |
Decision matrix
- Need 12V DC? The NDR-120-12 10A supply is the only 12V option here, and 10A gives you room for multiple loads.
- Need 24V DC and want to spend the least? The 120W 24VDC 5Amp Single Output DIN Rail Supply is the entry-level pick.
- Need 24V DC plus an Indoor/Outdoor installation area? Both NDR-120-24 entries list that rating, so choose either one.
- Need a 24V supply with input and efficiency specs? The 120W 24VDC unit explicitly lists a 100-240V input range and efficiency ≥85%.
Product notes
120W 24VDC 5Amp Single Output DIN Rail Supply

At $22.99, the 120W 24VDC 5Amp Single Output DIN Rail Supply delivers 24V DC at 5A for the lowest listed price here. Its 100-240V AC input range, 50/60Hz, and ≥85% efficiency are stated, which helps if you need to compare operating specs. The compact 1.7 x 4.8 x 5.1in footprint and single-output layout make wiring straightforward in a shallow cabinet. The limitation: this supply is 24V-only, so it cannot run 12V devices; if your loads need 12V, the NDR-120-12 is the one to select.
NDR-120-12 10A 12V DIN Rail Supply

The NDR-120-12 10A DIN Rail Supply is the only unit in this group with a 12V output, and its 10A rating delivers twice the current of the 24V models. Priced at $39.99, it has a blue DIN-rail-mount housing and an Indoor/Outdoor installation area. If your controls or sensors run on 12V, this is the clear pick; the 10A capacity leaves headroom for multiple loads. Its limitation is that the lower voltage does not suit 24V equipment, and at $17 more than the entry-level 24V supply, you pay extra for that 12V niche.
NEW NDR-120-24 Industrial DIN Rail Power Supply

The NEW NDR-120-24 Industrial DIN Rail Power Supply is priced at $44.99 and provides 24V DC at 5A with a blue DIN-rail-mount housing and an Indoor/Outdoor installation area. It also carries a 5A inrush current rating, which is useful for startup planning. As a 24V/5A supply, it matches the output voltage and current of the much cheaper single-output unit, so the higher price buys the NDR model identity and the installation-area rating rather than more power. The limiting factor is that $22 gap: for the same core output, you are paying a substantial premium.
5A Industrial DIN Rail Power Supply NDR-120-24

The 5A NDR-120-24 is the MW-branded version of the NDR-120-24 pair, also priced at $44.99. It shares the blue housing, Indoor/Outdoor installation area, DIN Rail mounting style, and 24V/5A output with the other NDR-120-24 unit. If you want a 24V supply from the NDR line with an outdoor-capable installation rating, this one works just as well as its counterpart. The limitation is that it cannot serve 12V loads, and the $22 premium over the 120W 24VDC single-output supply is significant unless you specifically need the NDR form factor or the MW label.
Final recommendation by use case
- For 12V controls: Choose the NDR-120-12 10A supply. It is the only 12V unit here and gives you 10A for the rail.
- For 24V on a budget: Choose the 120W 24VDC 5Amp Single Output DIN Rail Supply. It provides the needed 24V/5A and keeps spend low.
- For 24V with an Indoor/Outdoor rating: Choose either the NEW NDR-120-24 or the 5A NDR-120-24; they have the same output current and installation area, so pick the one you prefer.
