Quick take
Choosing a DIN rail power supply starts with the DC voltage your controls need. These four supplies span 12V, 24V, and 36V DC outputs, with listed prices from $19.99 to $49.00. Two are listed as new and two as used. If you need 24V and want a new unit, the Mean Well NDR-120-24 is a new listing at $31.64. If 24V at higher current matters more and you are comfortable with a used unit, the PULS Dimension CP10.241 at $42.74 supplies 24V and 10A. The $19.99 unit is the only 12V supply here, and the $49.00 PULS QS20.361 is the only 36V option.

Product notes
PULS QS20.361 DIN Rail Power Supply 36V DC Industrial PSU
At the top of the listed price range, this PULS unit is the only 36V DC option in this group. The listing says it is used and will show light wear from previous use; the items shown in the pictures are the only ones included. That makes it a targeted pick when your equipment genuinely runs on 36V rather than 24V or 12V. Because it is a used item and still carries the highest listed price, confirm the 36V requirement before choosing it.
Mean Well NDR-120-24 AC/DC Single Output Industrial DIN Rail Power Supply
The Mean Well NDR-120-24 is listed as new, and the description specifies 24V DC at 5A with 120W output and a universal AC input range. Its listed price sits between the lowest and highest options in this lineup. The main constraint is the 5A output: it cannot match the 10A current delivery of the used PULS CP10.241. The description also notes no PFC function, so that is worth keeping in mind for your panel's power quality expectations.
120W 12VDC 10Amp Industrial DIN Rail Power Supply Single Output 1.7x 4.8 x 5.1in
This supply carries the lowest listed price of the four, and its title promises 120W, 12VDC, and 10Amp output in a compact 1.7 x 4.8 x 5.1 inch size. The description lists efficiency at ≥85% and input of 100-240V. For a 12V control circuit, this unit gives you 120W of capacity at the same power level as the Mean Well 120W model. Because it is 12V-only, it will not run 24V or 36V equipment, so its usefulness depends entirely on your rail being a 12V rail.
PULS Dimension CP10.241 DIN-Rail Power Supply 24V 10A 240W - 1-Phase
The title states 24V, 10A, and 240W, making this used PULS unit the higher-current 24V choice in the lineup. The description adds a wide-range 100-240V AC input, convection cooling with no fan, and 35mm DIN-rail mounting. It is described as used with minor cosmetic wear and includes no cables or accessories. That means the supply itself is the main deliverable. If your 24V system needs more than the 5A a new Mean Well unit provides, this is the unit to favor, with the used condition as your trade-off.
Final recommendation by use case
- For a 36V application: choose the PULS QS20.361.
- For a new 24V supply where 5A is enough: choose the Mean Well NDR-120-24.
- For 24V at 10A: choose the PULS CP10.241 and accept a used unit.
- For 12V loads and the lowest listed price: choose the 120W 12VDC DIN Rail Power Supply.
