LevelOne POW-2441 Industrial DIN-Rail Power Supply 24V DC 120W, Universal 90–264V AC Input, Fanless, Silver

The LevelOne POW-2441 is an industrial 24 V DC power supply rated at 120 W (5 A) that clips onto a standard 35 mm DIN rail, made for control cabinets that power switches, controllers and sensors. 24 V DC is the standard control voltage for PLCs, industrial switches, I/O modules and sensors, and the universal 90–264 V AC input (or 127–370 V DC) means the same unit works on any mains supply.

It is fanless and cooled by free air convection, so there is nothing to wear out or clog with dust, and it carries short-circuit, overload and over-voltage protection. The output can be trimmed from 24–28 V to compensate for voltage drop on longer cable runs. It is rated for -20 to 60 °C ambient and 20–95 % humidity.

• LevelOne POW-2441 DIN-rail power supply

• Mount it on the same 35 mm DIN rail as your industrial switch or controller and wire mains (L/N/PE) and the DC output to the screw terminals — no separate enclosure needed inside a cabinet.
• Size it with headroom: add up the maximum consumption of everything on the 24 V bus and keep it comfortably below 120 W.
• Use the voltage trim (24–28 V) to bring the voltage at the far end of a long DC run back to nominal.
• Rated for -20 to 60 °C operation, it suits ventilated cabinets in plant rooms and workshops.

• It has no mains cable or plug — it must be wired into terminals by a qualified electrician inside a cabinet.
• It does not deliver 48 V, so it cannot feed the PoE side of a switch that needs 48–56 V input for PoE.
• It is not a UPS: if mains power fails, the output drops after the short hold-up time.
• It is not rated for outdoor exposure on its own; install it inside a closed cabinet.
