DWL-P50

5VDC/12VDC Power Over Ethernet Adapter

The DWL-P50 Power over Ethernet adapter is a single-port injector that provides DC power for a non-PoE-equipped device,
such as a surveillance camera or a wireless access point. It is designed to operate with LAN switches and other equipment that
support industry-standard 802.3af Power over Ethernet (PoE) to deliver operation power to the networked device, allowing you
to install the device at places such as on a rooftop or near a ceiling, where power is not easily accessible. The DWL-P50
supports both 5VDC and 12VDC power and can be flexibly deployed with network devices with different power voltage
requirements.

Facilitates Installation

The DWL-P50 is useful for installation at a factory or

TM

Wi-Fi hot spot. This compact adapter allows you to install
your surveillance cameras and wireless LAN devices on a
building rooftop, on or near a ceiling for maximum
coverage. Your cameras or wireless access points can be
placed up to 100 meters away from a power source. It is at
these places that wall AC outlets are inaccessible and
providing power to these locations is difficult and
expensive. The DWL-P50 is also handy for installation at
offices with Internet telephones connected to a PoE
Ethernet switch. It eliminates the need to individually
power each IP phone. By transmitting remote power
through the standard network cabling, the DWL-P50 does
away with the need for an AC outlet at each device location.
Only a single Ethernet cable is run to each device instead of
separate power and data cables.

Data and DC Power Transmission on the Same
Network Cable

On a standard 4-wire UTP Category 5 cable, only two pairs
(pins 1, 2, 3 and 6) are used for Ethernet data transfer. At
one end, your PoE Ethernet switch inserts DC voltage into
the unused wires, taking advantage of the unused pair of the
network cable wires. At the other end, the DWL-P50 taps

the DC power from the Ethernet cable for use by the non­PoE device. Consequently, a single Category 5 cable can
now carry both Ethernet data and DC power. The idea is to
supply the remote end with power and Ethernet connectivity
via a single network cable.

Centralized Power Provision, Easy Deployment

In addition to eliminating the need for additional, separate
wiring for power, the DWL-P50 is also a useful tool that
forms part of your centralized power network installation. A
central UPS can be added to the PoE switch, to which all
your wireless access points, surveillance cameras and
Internet phones are connected. This installation provides
uninterrupted power without the need to deploy a separate
UPS for each device.

Very Compact Size, Simple Installation

The DWL-P50 is very small in size and lightweight and
requires no configuration setting. It is designed for quick and
easy deployment, and can be hooked with a simple plug to a
network device placed on a high wall or ceiling. This PoE
adapter supports both 5V and 12V DC output, allowing you
to deploy it with a variety of devices with different power
requirements. A built-in slide switch allows you select the
required power output.
