LevelOne POW-4801 is a compact indoor power supply that delivers 48V DC at up to 64W for network equipment and other devices that require a 48V DC input. The package includes a 48V AC power adapter and a DC power jack converter that allows connection to devices with a DC terminal block when only an AC outlet is available. The unit is UL, cUL, TUV and CE marked and has a rated input range of 110–240V AC and an MTBF of approximately 25,000 hours.

Advantages

The POW-4801 combines an AC-to-DC adapter and a DC jack converter into a single solution, simplifying connection of legacy or terminal-block devices to standard AC mains. It supplies up to 64.8W of output power and includes built-in protections for overvoltage, overcurrent and short circuit, protecting both the supply and connected equipment. The compact black casing and international input range make it suitable for diverse indoor installation environments.
