Choosing a 24V DIN rail supply for an industrial panel often comes down to two nearly identical specification blocks. When you're comparing industrial power supplies transformers, the practical decision in front of you is a 120W 24VDC 5A DIN Rail Power Supply and a Mean Well EDR-120-24. Both accept 100-240VAC input, and both are built for 24VDC at 5A. The real difference is a $5.01 price gap.
Quick verdict
If your priority is keeping the cost down on a compact DIN rail supply, choose the lower-priced 120W 24VDC 5A DIN Rail Power Supply. If you want the named EDR-120-24 part number on the unit, choose the Mean Well EDR-120-24. Both DIN rail supplies target the same working output, so the decision is price versus part-number identification.

Where each product wins
Choose the 120W 24VDC 5A DIN Rail Power Supply for the lower price and compact size
This supply lists a compact 1.7 x 4.8 x 5.1-inch body and an efficiency rating of at least 85%. If the panel has limited space or the unit runs for long periods, those details matter. It gives you the same 120W capability as the other option without the added cost.
Choose the Mean Well EDR-120-24 for the named part number
The EDR-120-24 model designation is right in the product name. If a replacement order or panel drawing needs a specific part number, that model name does the work for you. The extra cost buys that identification clarity.
Product notes
120W 24VDC 5Amp Industrial DIN Rail Power Supply Single Output 1.7 x 4.8 x 5.1in
This is the lower-priced option in the pair. Its reason to stand out is the combination of a compact 1.7 x 4.8 x 5.1-inch body and an efficiency rating of at least 85%, both useful when you are placing a supply in a tight control cabinet and want to keep waste heat down. The trade-off is identification: the title describes the unit by its output and dimensions rather than by a specific model number, so you won't find an EDR-120-24-style part number to write into cabinet documents. For a non-critical replacement or a prototype panel, that is a fair trade.
DIN Rail Power Supply, EDR-120-24, Mean Well, 24VDC , 5A, 120W,Input :100-240VAC
Here the reason to choose is the EDR-120-24 designation itself. That model number appears directly in the product name, which makes it easier to reference in inventory or reorder a matching supply later. The unit is described as new. The limitation is price, because $28.00 sits at the high end of the $22.99-$28.00 range; you are paying the $5.01 difference for the named model. When ordering spares, that part number is enough to identify the unit without digging through specifications.
Final choice by use case
If your panel doesn't require a named part number, use the 120W 24VDC 5A DIN Rail Power Supply to keep the cost down. If you want the EDR-120-24 model number to follow a spare part through inventory, use the Mean Well EDR-120-24. Both units share the same working specification, so the final pick comes down to how much the model number is worth.
