ATTE ASDC-12-120-HS Passive PoE Adapter – 18-56V DC Input, 12V 1A Output, 10/100 Mbps

Voltage drop and incompatible power sources often prevent reliable operation of 12V DC devices when they are deployed beyond the reach of standard power delivery. The ATTE ASDC-12-120-HS passive PoE adapter solves this by accepting a wide DC input range from 18 to 56 volts and delivering a regulated 12V/1A output to the connected equipment. This enables network professionals to power devices through existing Ethernet infrastructure without the need for additional power cabling.

Who is it for

Ideal for installers and IT professionals working with IP cameras, VoIP phones, wireless access points, and other 12V devices in locations where a power outlet is unavailable. It allows you to use existing PoE network infrastructure and avoid the cost of running separate power cabling.
