When you're choosing industrial power supplies transformers, the first decision is what your line actually needs. These two options sit on opposite ends of that choice. The Used & Tested REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply lists at $2,474.68, while the NEW NDR-120-24 Industrial DIN Rail Power Supply lists at $44.99. Both are legitimate, but they serve completely different loads.
Quick verdict
If you need 30 kW of high-power output and are comfortable with a used & tested unit backed by a 2-year warranty, the REXROTH is the fit. If you just need clean 24V DC for control circuits and want a new unit that snaps onto a DIN rail, the NDR-120-24 is the practical choice.
| Product | Listed Price | Condition | Output / Input |
|---|---|---|---|
| Used & Tested REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply | $2,474.68 | Used & Tested | 400-480 V input, 30 kW output |
| NEW NDR-120-24 Industrial DIN Rail Power Supply | $44.99 | New | 24 V output, 5 A |
Where each product wins
- The REXROTH wins for heavy automation lines that need 30 kW and 400-480 V input. Its used & tested status plus the included warranty adds confidence.
- The NDR-120-24 wins for 24V control panels. It's new, fits a DIN rail, and its list price is far lower than the REXROTH's.
Product notes
Used & Tested REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply
The REXROTH HMV01.1E-W0030-A-07-NNNN is a heavy-duty control power supply built for serious production lines. It accepts 400 to 480 V input and delivers 30 kW, so it can handle large servo drives, machine tool axes, and whole automation cells. The listing marks it as Used & Tested, which indicates each unit has passed a functional check, and the 2-year warranty plus 60-day money-back provides a safety net. For an existing machine with a failed supply, this is a direct replacement path. The tradeoff is the list price: $2,474.68, which is $2,429.69 more than the NDR-120-24. The used condition also means it may not suit facilities that require factory-fresh parts. With 30 kW on tap, it is a significant investment aimed at high-power applications.
NEW NDR-120-24 Industrial DIN Rail Power Supply
The NDR-120-24 is a straightforward new DIN rail power supply for control panels that need 24V DC. It outputs 24 volts at 5 amps, which is enough for PLCs, contactors, relay modules, and sensors. Its DIN rail mount lets you snap it onto standard rail quickly, and the blue housing is easy to spot in a crowded panel. The list price is $44.99, which is $2,429.69 below the REXROTH's price. That makes it an easy add for low-voltage control circuits or spare parts inventory. The limitation is output capability: 5A at 24V cannot drive high-wattage loads or accept 400V inputs. If your panel only needs 24V control power, this new unit delivers a straightforward, low-price solution.
Final choice by use case
Choose the REXROTH HMV01.1E for large industrial lines, multi-axis machines, or any process that needs 30 kW of reliable power and where a used & tested unit with warranty fits your maintenance plan.
Choose the NDR-120-24 for new control panels, DIN rail assemblies, and any circuit that runs on 24V DC. It is new, compact, and designed for DIN rail, so it keeps a low-voltage control build simple.
