When you're shopping for industrial power supplies and transformers, the first decision is usually output voltage. Two PULS power supplies show how that choice plays out. The ML50.102 gives you an adjustable 12-15V DC output at up to 4.2A (50W), while the QT20.241 delivers a fixed 24V DC output from a 480VAC input.
Quick Verdict
If your control circuit runs on 12-15V DC, the ML50.102 is the straightforward pick because it is new, adjustable, and suited to lower-voltage loads. If you need 24V DC and your panel is fed by 480VAC, the QT20.241 is the appropriate choice, though you'll be accepting an open-box condition.

Where Each Product Wins
The ML50.102 wins where you need a lower-voltage supply with some flexibility. Its output can be adjusted within the 12-15V DC range, and its 4.2A / 50W rating is enough for many control panels. It is also listed as new, which may give you more confidence than an open-box unit.
The QT20.241 wins where 24V DC is non-negotiable. It accepts a 480VAC input directly, which is a common industrial voltage, and steps it down to 24V DC without needing an extra transformer. That makes it a simpler solution for high-voltage installations.
Product Notes
PULS ML50.102

The PULS ML50.102 is a new, compact power supply that outputs an adjustable 12-15V DC and delivers up to 4.2A, making it a strong fit for factory automation, instrumentation, and control panels running on lower DC voltages. Its 50W rating supports modest loads, and the space-saving design works well in crowded enclosures. Choose it when you need a flexible lower-voltage rail and want a new-condition unit. The key limitation is the voltage ceiling: it tops out at 15V DC, so it will not power 24V equipment. If your system requires 24V, look to the other unit.
Puls QT20.241

The Puls QT20.241 is designed for industrial setups that need 24V DC and have 480VAC available at the input. The DIN rail mounting makes installation straightforward, and the direct 480VAC feed removes the need for an additional step-down transformer. Its fixed 24V DC output suits standard controls, sensors, and actuators. Choose this unit when 24V is a firm requirement and your facility provides 480VAC. The limitation is the condition: it is listed as new open-box, so the packaging may have been opened even though the supply is described as new. For a sealed, untouched unit, the ML50.102 may be a safer bet.
Final Choice by Use Case
Choose the PULS ML50.102 for applications that operate on 12-15V DC, especially if you want a new unit with an adjustable output. Choose the Puls QT20.241 for 24V DC requirements when your incoming supply is 480VAC, and you are comfortable with a new open-box product. Match the supply to the load voltage first; price and condition then decide the rest.
