When a control cabinet needs a 12V rail, the choice often comes down to two DIN rail industrial power supplies with opposite strengths. The PULS ML50.102 offers an adjustable 12-15V DC output in a compact unit. The Mean Well MDR-100-12 delivers more current at a lower listed price. The right pick depends on whether your panel needs voltage flexibility or raw output.
Quick Verdict
Pick the PULS ML50.102 if you need a 12-15V adjustable output and your load stays within 50W. It is the cleaner fit for control cabinets, factory automation, and instrumentation that benefit from a stable, compact supply. Pick the Mean Well MDR-100-12 if you want 90W of 12V rail power with 7.5A of current and prefer the lower listed price.
At a Glance
| Product | Output | Current | Power | Price |
|---|---|---|---|---|
| PULS ML50.102 | 12-15V DC adjustable | 4.2A | 50W | USD 61.22 |
| Mean Well MDR-100-12 | 12V DC | 7.5A | 90W | USD 29.99 |
Where Each Product Wins
- The PULS ML50.102 wins when voltage range matters. Its adjustable 12-15V output gives you room to set the rail to the voltage your equipment needs.
- The Mean Well MDR-100-12 wins when current and price matter. Its 7.5A output and 90W rating out-carry the PULS, and its list price is the lower of the two.
Product Notes
PULS ML50.102
The PULS ML50.102 is a switched-mode DIN rail supply rated at 12-15V DC, 4.2A, and 50W. The unit has a compact design and is suited to control cabinets, factory automation, instrumentation, and sensitive electronic equipment. The adjustable output is its strongest reason to pick it: rather than accepting a single voltage, you can match the rail to the value your circuit actually needs. The tradeoff is capacity. At 4.2A and 50W, it carries less current than the Mean Well, and it comes with a higher list price. If your automation load is modest and voltage flexibility matters more than raw current, this is the supply to put in the panel.
MDR-100-12
The MDR-100-12 is an enclosed plastic AC/DC converter for DIN rail mounting, and its title lists a 12V output at 7.5A with 90W of power. The feature set includes an LED indicator and a DC OK signal, so you can see when the rail is live without reaching for a meter. The current rating is the main reason to choose it: 7.5A gives you more room to feed multiple devices on the same 12V rail. The limitation is voltage range. This unit is listed as a 12V supply rather than a 12-15V adjustable model, so it won't offer the same adjustment flexibility as the PULS. For straightforward 12V power at the lower listed price, it is the one to choose.
Final Choice by Use Case
Choose the PULS ML50.102 for adjustable 12-15V output in a compact, stable supply aimed at control cabinets and factory automation, especially when your load sits under 50W. Choose the Mean Well MDR-100-12 for a higher-current 12V rail at 90W and a lower listed price, particularly when voltage range is not part of the job.
