## Summary description

Passive step-down PoE adapter Atte ASDC-12-120-HS converts Power-over-Ethernet to a 12V DC output for powering devices that require 12 volts. The adapter is a passive PoE converter designed to feed cameras, routers, access points or other 12V equipment where active PoE negotiation is not required. Suitable for installations needing simple power delivery over Ethernet cabling.

## Long description

The Passive Step-Down PoE Adapter Atte ASDC-12-120-HS provides a simple conversion from Power-over-Ethernet to a stable 12V DC output for devices that require a twelve-volt supply. This passive PoE adapter does not perform active PoE negotiation; instead it accepts power delivered over Ethernet and steps it down to a fixed 12V output suitable for many networked devices. The compact converter is intended for installations where straightforward power delivery over existing Ethernet cabling is preferred to running separate power lines.
Advantages
The adapter offers a compact, low-complexity solution to supply 12V devices via Ethernet cabling, minimizing the need for additional power outlets or adapters near the powered device. Because it is a passive step-down unit, it is compatible with setups that supply constant DC over PoE feed lines and provides a consistent 12V output without requiring negotiation with PoE switches. The converter’s design allows easy integration with cameras, routers and access points that accept a 12V input.
Suitable for
 IP cameras and surveillance equipment requiring 12V DC
 Wireless access points and small routers that accept 12V input
 Network devices in locations without convenient mains power
 Retrofit projects using existing Ethernet cabling to deliver power
Key specifications
 Output voltage: 12V DC nominal
 Function: passive PoE to 12V DC step-down conversion
 Target devices: low-voltage network equipment (cameras, APs, routers)
 Mounting/installation: inline converter for Ethernet cable runs
How to use
Connect the adapter inline between the Ethernet cable that carries the DC power and the device requiring 12V. Ensure the power source on the Ethernet feed provides the appropriate DC and polarity expected by this passive converter; confirm device compatibility with a fixed 12V supply before connecting. After connection, verify the powered device receives stable 12V and operates normally. If necessary, secure the adapter to prevent strain on connectors and protect it from moisture or mechanical damage.
Usage recommendations
Use this passive PoE adapter only where the Ethernet feed provides a compatible DC supply and active PoE negotiation is not required. Do not connect to standard 802.3af/at PoE ports that expect negotiation unless you are certain they provide a compatible passive output. For outdoor or exposed installations, protect the adapter and connections with appropriate enclosures and follow cable and device manufacturer guidance for safe power delivery.
