When you're choosing among industrial power supplies transformers, the decision often comes down to matching the supply to the load. On one side is a heavy-duty control power supply for a large automation cabinet; on the other is a control supply for smaller circuits. This head-to-head compares the REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply with the MW NDR-120-24 24 Volt 5 Amp DIN Rail Power Supply, so you can see which one fits your system.
Quick Verdict
If your control panel needs high-output power, the REXROTH HMV01.1E is the stronger candidate. If you need a supply for lower-voltage control circuits, the MW NDR-120-24 is the practical choice. Their listed prices sit about $2,429.69 apart, but the gap reflects two different jobs rather than one product being better than the other. Which one suits your cabinet depends on the voltage you have on site and how much output the load actually draws.
At a Glance
| Product | Price | Condition | Key specs | Best fit |
|---|---|---|---|---|
| REXROTH HMV01.1E-W0030-A-07-NNNN | USD 2,474.68 | Used & Tested | 400-480V input, 30 kW output | High-output control power |
| MW NDR-120-24 | USD 44.99 | New | 24V, 5A output, DIN rail mount | Compact control panels |
The two units sit at different ends of the same category, so the right pick depends on the size of the load and the installation style.
Where Each Product Wins
Where the REXROTH HMV01.1E wins: This supply makes sense for a large machine or automation line that draws serious power. It belongs on the high-output side of the category.
Where the MW NDR-120-24 wins: This supply makes sense for lighter loads where a simple unit is a better fit, especially when an indoor/outdoor installation rating helps.
Product Notes
REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply

The REXROTH HMV01.1E is built for heavy lifting. Its 400-480V input and 30 kW output put it in a different class from a small panel supply, and it suits applications where a machine-tool or automation bus needs substantial power. Because it is offered as a used and tested unit, the deal includes a two-year warranty, a 60-day money-back window, and lifetime professional support, which is more reassurance than you might expect from pre-owned industrial gear. The main limitation is the condition and the input requirement: a used supply and a 400-480V feed are not ideal for every shop. If your system already runs on that voltage, this is a serious candidate.
MW NDR-120-24 DIN Rail Power Supply

The MW NDR-120-24 takes the opposite approach. It is a new, blue DIN-rail-mount supply delivering 24V at 5A, which suits modest loads and typical control circuits. The new condition removes the uncertainty of buying used gear, and the DIN rail mount makes installation direct in a standard enclosure. For a panel with a 24V control bus, this is the straightforward option. The limitation is capacity: this is a 24V/5A unit, so it will not drive high-power equipment or carry the input range of a large control supply. For lighter automation tasks, it is the more convenient, low-fuss choice.
Final Choice by Use Case
Choose the REXROTH HMV01.1E if your priority is high-output control power for a large automation application. Choose the MW NDR-120-24 if your priority is a straightforward supply for lighter automation.
