If you are in the market for an industrial power supplies transformers setup, the decision often starts with scale: do you need a high-output control power supply or a low-voltage unit for modest loads? The REXROTH HMV01.1E-W0030-A-07-NNNN and the MW NDR-120-12 show how different those requirements can be. One is built for heavy lifting, while the other is positioned for simpler, lower-current jobs.
Quick verdict
The REXROTH HMV01.1E-W0030-A-07-NNNN is a high-output control power supply geared toward installations where output is the priority. The MW NDR-120-12 is a low-voltage power supply for lower-current circuits. Their prices sit $2,434.69 apart, which tells you these are not really competing for the same slot. Choose the Rexroth when output capacity dominates. Choose the MW when the load is modest and you want a lower-cost alternative.
| Product | Price | Relative price | Condition | Key specs |
|---|---|---|---|---|
| REXROTH HMV01.1E-W0030-A-07-NNNN | USD 2,474.68 | Used & tested | 30 kW output, 400-480 V input, 48-62 Hz | |
| MW NDR-120-12 | USD 39.99 | New | 12V output, 10A, 120W, DIN rail mount |
Where each product wins
- The Rexroth wins when your industrial application calls for a serious amount of output power. That is the first filter: if the machine needs far more than a low-voltage supply can deliver, the Rexroth is the one to look at.
- The MW wins when a modest, lower-current supply is all the load requires. It is the easier choice for everyday low-voltage circuits, especially when rail mounting is part of the plan.
Product notes
REXROTH HMV01.1E-W0030-A-07-NNNN
The REXROTH HMV01.1E-W0030-A-07-NNNN carries a 30 kW output rating, an input voltage range of 400 to 480 V, and a frequency rating of 48 to 62 Hz. Those numbers place it on the high-capacity end of the industrial power supplies transformers range. It comes in used condition, and the purchase includes a two-year warranty and a 60-day money-back window; those protections matter more when you are buying a unit that has already been in service. What holds it back is that it is not new, so you are accepting prior service life, and you also need an incoming supply in the 400-480V band, which is a specific input range to plan for. If your machine genuinely requires this output level, the Rexroth gives you the headroom, and the warranty softens the used-condition risk.
MW NDR-120-12
The MW NDR-120-12 is the other end of the spectrum. It is a new 12V DIN rail power supply rated for 10A and 120W. Its nominal current and power ratings make it appropriate for lower-current circuits rather than high-load machinery, so the choice often comes down to whether your load fits comfortably inside that envelope. The mounting style is DIN rail, and the installation area includes indoor and outdoor locations, which gives you placement flexibility in a range of industrial environments. Because it is new, you avoid the used-condition concerns that come with a high-output unit like the Rexroth. On the other hand, it is limited by capacity: 12V, 10A, and 120W will not drive large motors or high-draw equipment. For a modest 12V load, this is a clean, rail-mounted solution.
Final choice by use case
If your machine or control system needs a significant amount of power and your incoming feed matches its high-voltage input range, the REXROTH HMV01.1E-W0030-A-07-NNNN is the unit to plan around. If you are rolling out a low-voltage control circuit with modest current draw, the MW NDR-120-12 is the sensible pick. Start with the load, not the brand: when the load is low, the low-voltage unit keeps the project simple; when the load is high, the Rexroth's output capacity is the reason to choose it.
