Choosing the right industrial power supply isn't about case color or brand preference; it's about matching the input voltage to your plant feed and the output to the load. The 120W 24VDC DIN Rail Power Supply and the REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply sit at opposite ends of that matching puzzle, and the right pick depends on which end your machine belongs to.
Quick verdict
If you need a 24 V DC feed from a compact DIN rail unit, the 120W 24VDC DIN Rail Power Supply at $22.99 is the practical choice. If your automation line already runs on a 30 kW Rexroth HMV01.1E control power supply with 400-480 V AC input, the used & tested REXROTH HMV01.1E-W0030-A-07-NNNN at $2,474.68 is the model to match.

Where the 120W DIN rail supply wins
The 120W unit is compact and gives you a fixed 24 V DC output at 5 A, which is the kind of bus that feeds relays, sensors, PLCs, and small solenoid networks. The rail-mount format saves panel space, and the input range covers common AC cabinet feeds.
Where the Rexroth HMV01.1E wins
The Rexroth part is built for much larger loads. It pairs with higher-voltage industrial distribution and offers an output scale the DIN rail supply cannot touch. If your machine already uses this exact part, the replacement matches the control system.
Product notes
120W 24VDC DIN Rail Power Supply
With a 24 V DC output rail at 5 A, the 120W 24VDC DIN Rail Power Supply covers the loads you usually find inside a small control cabinet: relays, indicators, sensors, and logic supplies. The 1.7 x 4.8 x 5.1 in case fits on standard DIN rail, and the unit draws up to 2.6 A while converting at an efficiency of at least 85%. New condition makes it a sensible first choice for those 24 V cabinet loads. The limitation is capacity: once you step up to drives, motors, or anything pulling more than 24 V DC at 5 A, this supply is out of its depth; it should stay on low-voltage, low-current duty.
REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply
The REXROTH HMV01.1E-W0030-A-07-NNNN Control Power Supply is the matching part for high-power automation systems. The used & tested condition includes a 2-year warranty, 60-day money-back window, and lifetime professional support, which takes some risk out of buying a used industrial component. The input side is designed for the higher-voltage industrial feed, and the control power supply format is built for a larger cabinet layout. The main limitation is fit: this unit will not make sense if you just need a 24 V DC bus, because its input voltage and output scale are tuned for the HMV01.1E system, not for low-voltage controls. Choose it when the rest of the machine already expects this specific Rexroth part.
Final choice by use case
Pick the 120W 24VDC DIN Rail Power Supply for low-voltage control cabinets that need a new, compact 24 V DC source. Pick the REXROTH HMV01.1E-W0030-A-07-NNNN for high-power automation lines that already use this Rexroth control power supply and need a used & tested replacement with warranty and support.
