When you're building or updating a control cabinet, the DIN rail power supply is the component that turns incoming AC into the clean DC your controls depend on. In the industrial power supplies transformers aisle, the PULS ML50.102 and the NEW NDR-120-24 are two compact DIN rail units that take different approaches. The PULS offers an adjustable 12-15V DC output for mixed loads, while the NDR is set at a 24V DC output. Your choice comes down to whether you need voltage versatility or a straightforward 24V feed for common automation parts.
Quick verdict
If most of your loads run on 24V-relays, small contactors, indicator lamps-the NEW NDR-120-24 is the simpler, lower-cost pick at $44.99. Its 5A output gives you a comfortable margin for a small panel. If your cabinet mixes 12V and 15V sensors, modules, or instruments, the PULS ML50.102's adjustable output is worth its $61.22 price, but you'll accept a lower 4.2A current ceiling.

Where the PULS ML50.102 wins
The PULS ML50.102 is the more flexible supply. Its output voltage is adjustable across the 12-15V range, which matters if you're powering instrumentation that expects 12V or analog circuits that need a precise 15V rail. It's also built with a compact switched-mode design that fits tight enclosures, and the model number ML50.102 makes it easy to specify as a replacement. The trade-off is that you accept a lower maximum current of 4.2A compared with the NDR's 5A.
Where the NEW NDR-120-24 wins
The NEW NDR-120-24 wins on current. It delivers 5A at the standard industrial voltage of 24V DC, which covers a wider range of control components. The blue housing is a common visual cue for DIN rail gear, and the inrush current rating of 5A is a listed spec you can factor into your branch circuit planning.
Product notes
PULS ML50.102 DIN Rail Power Supply

The PULS ML50.102 is a compact switched-mode supply with an adjustable 12-15V output. That makes it a strong fit for control panels that mix sensors, indicators, and small electronic modules running at different voltages. The 50W rating aligns with the 4.2A output, so it's designed for lower-current applications where stable voltage matters more than raw power. Its DIN rail mounting keeps installation simple, and the model number ML50.102 gives you a clear reference for replacement or ordering. The trade-off is that this adjustable capability costs more than the NDR-120-24 while delivering less current. If most of your cabinet runs on 24V, you'll pay a premium for adjustability you may never use.
NEW NDR-120-24 Industrial DIN Rail Power Supply

The NEW NDR-120-24 is a 24V DC supply rated at 5A, a very common combination for industrial control wiring. It offers a lower price entry point for a standard 24V automation panel, and the blue housing and DIN rail mounting style match the usual control-cabinet layout. The inrush current rating of 5A is worth keeping in mind when planning your branch protection. The output is 24V DC, so a panel built around 12V or 15V circuits would need a different supply; for a basic 24V control system, this unit can handle several small loads without overthinking the setup. The model number NDR-120-24 points to the 24V family, and the 5A output provides adequate current for a typical small enclosure.
Final choice by use case
If you're outfitting a standard 24V control panel with relays, contactors, and small actuators, the NEW NDR-120-24 gives you the current and the simpler specification for the job. If you need to power mixed 12V and 15V instrumentation and want to tune the output without swapping modules, the PULS ML50.102's adjustable output justifies the extra spend. For a pure 24V system, the NDR-120-24 is the straightforward buy; for a panel with varied voltage needs, the PULS is the more capable partner.
