LevelOne POW-4821 — 48 V, 75 W DIN-rail PSU

48 V / 1.6 A75 W classFor PoE gearFanless

The LevelOne POW-4821 is a 48 V DC industrial power supply for a 35 mm DIN rail, rated 1.6 A (76.8 W) in LevelOne’s 75 W class. It accepts a universal 90–264 V AC or 127–370 V DC input, cools by free-air convection without a fan, and has short-circuit, overload, over-voltage and over-temperature protection. The output is adjustable from 48 to 55 V, which is why LevelOne names it for powering PoE switches, injectors and telecom equipment. It works from −20 to +60 °C. In practice it is the supply that feeds a small industrial PoE switch in a cabinet.

Compatibility — check before buying:
75 W total is the limit for everything connected. A PoE switch passes most of this power to its cameras or APs, so add up the devices before choosing; for larger PoE budgets LevelOne offers the POW-4851 (48 V, 240 W). Installation by a qualified person with earth connection is required — there is no mains plug. Not sure? Tell us your model and we check it for you.

Frequently Asked Questions

Can it power an industrial PoE switch?
Yes, if the switch plus all powered devices stay within about 75 W.
Can I raise the voltage?
Yes, the output adjusts from 48 to 55 V.
Does it have a fan?
No, it is fanless.
I need more PoE power — which model?
LevelOne POW-4851, 48 V 240 W.
Singular Expert Insight
For PoE, budget the supply first: two 802.3at cameras plus the switch already use most of 75 W. Setting the output to about 52–54 V helps PoE reach at longer cable runs. For industrial PoE switches, see our PoE switches.
