Choosing between a compact DIN Rail power supply and a high-power control power supply for your industrial setup comes down to one central question: what voltage does your system need on the output side? The Mean Well EDR-120-24 is a compact DIN Rail unit. The REXROTH HMV01.1E is a control module for larger machines. They are not interchangeable, but both belong to the industrial power supplies transformers family, and picking the wrong one can stall a project.
Quick verdict
Pick the Mean Well EDR-120-24 when your panel needs a dependable low-voltage DC rail for control circuitry. Pick the REXROTH HMV01.1E when you are servicing a machine that already uses a REXROTH HMV01 power stage. The listed prices sit far apart because the two products solve completely different problems.

Where each product wins
Mean Well EDR-120-24 wins if...
You are building or repairing a standard control cabinet. It runs on a typical AC input, produces a clean DC bus for small loads, and the lower listed price makes it a simple line item.
REXROTH HMV01.1E wins if...
You need a high-power module for an existing machine's power bus. It gives you a service path for equipment that would otherwise be expensive to redesign. This is not a general-purpose supply; it is a direct module replacement.
Product notes
Mean Well EDR-120-24 DIN Rail Power Supply
The Mean Well is the spec-sheet opposite of the REXROTH. It is new, priced at USD 28.00, and designed for DIN rail mounting. It accepts 100-240VAC input and delivers a 24VDC, 5A output with 120W capacity, which is enough for control loads such as relays, indicators, and small PLCs. The limitation is that 120W will not run motors or high-current actuators, so you need to separate logic power from motive power. For that reason, it works best as the power supply inside a cabinet that controls a larger system rather than as the main drive supply. If you are stocking a panel shop or replacing a failed 24V supply in an existing cabinet, this is the straightforward choice.
Used & Tested REXROTH HMV01.1E Control Power Supply
The REXROTH is a major step up in power and price. It is listed as used and tested, with a 30kW rating and 400-480V input, and it costs USD 2,474.68. The reason to choose it is straightforward: if your machine calls for a HMV01.1E-W0030-A-07-NNNN, this is the exact service part. The limitation is equally clear: it is meant for that specific 400-480V bus architecture, not for general-purpose 24V use. The used-and-tested condition is part of the value and part of the risk, so factor that into your maintenance plan. This makes sense only when you already have a REXROTH-based motion system and need a drop-in replacement.
Final choice by use case
Choose the Mean Well when you want a compact supply for a control panel with modest DC loads. Choose the REXROTH when you need a high-power module for a larger machine's power bus. If your application is a simple cabinet, the Mean Well's lower price fits. If you are keeping an existing REXROTH system running, the HMV01.1E is the specific replacement to look for.
