POW-4842 — 48 V, 120 W DIN rail PSU

48 V / 120 W−20 to 70 °CFanlessDC OK relay

The LevelOne POW-4842 is a wide-temperature 48 V DC industrial power supply that delivers 120 W (2.5 A) on a 35 mm DIN rail. It runs continuously from −20 to +70 °C, accepts 90–264 V AC or 127–370 V DC, and is fanless. Short-circuit, overload and over-voltage protection guard the supply and the equipment, each unit is burn-in tested, and a DC OK relay contact reports status. In practice it powers 48 V equipment such as industrial PoE switches and injectors in unheated cabinets and outdoor enclosures.

Compatibility — check before buying:
For installation by a qualified person — screw terminals, earth connection required. The output is adjustable 48–55 V. The sibling POW-4841 has the same output but is rated to +60 °C and has no DC OK relay listed. For 24 V equipment you need a 24 V supply. Not sure? Tell us your model and we check it for you.

Singular Expert Insight
For PoE, remember the switch or injector needs 48–55 V; a 48 V supply set a little higher gives full PoE+ power. Size with 20–30% headroom. For industrial switches, see our PoE switches.
