The MOBOTIX Network Power Adapter Set (NPA-PoE set) is a high-quality, robust, ultra-compact and multifunctional
PoE injector with three connectors (network, camera/PoE device, PC) and a universal power supply unit with
interchangeable adapter plugs.
The Network Power Adapter Set remotely supplies all PoE devices with power in accordance with the IEEE
802.3af standard. This makes it possible to use the network cable to both connect the camera and remotely
supply power (up to 100m). As a result, a network camera can be supplied with PoE power via the adapter
and connected directly to your PC (integrated crossover function).
A further advantage of this product is its versatility. The blue adapter can be connected to dierent electrical power
supply networks around the world (90 V to 230V) using the power supply unit. The device can also be directly
connected to network-independent power sources between 12 V and 42V. This is ideal for battery-operated,
standalone operation of a network camera. This device is especially practical because the included power
supply unit can be used around the world by changing the adapter plugs as required with a few simple steps.

You can use the NPA-PoE Set to safely and reliably supply power to all of your MOBOTIX cameras (except for
M1/M10) and to the Mx2wire media converter.
The German company MOBOTIX AG is known as the leading pioneer in network camera technology, and
its decentralized concept has made high-resolution video systems cost-ecient. Whether in embassies,
airports, railway stations, ports, gas stations, hotels or on highways - over one hundred thousand MOBOTIX
video systems have been in operation on every continent for years. For more information on current MOBOTIX
Power Supply When Connected Directly To A PC (Integrated And Patented Crossover Function)
1. Connect the camera's Ethernet patch cable, or that of the PoE device that is to be supplied, to the "Camera"
connector of the blue adapter.
2. Connect the "PC/Power" connector of the adapter directly to the Ethernet port of the computer. The adapter
eliminates the need for the crossover cable thanks to the integrated crossover function.
3. Plug the RJ45 connector of the power supply unit/battery into the "LAN/Power" connector of the adapter.

Connection Cable To The Battery (Order Number: MX-CBL-NPA-BAT-2)
The blue adapter works reliably in an input voltage range of 12–42volts. When connecting the adaptor to a
mobile power source (for example, a car battery), the power supply unit is not used. Instead, you will need
a correctly prepared connection cable that is, if possible, equipped with a fuse protection concept suitable
for your application.
The connection cable must have a "+/-" connection to the battery on one side and, on the
other side, an RJ45 connector to connect to the adapter. Pins 4 and 5 on the RJ45 connector must display a "+",pins 7 and 8 a "-."Caution: Do not use a patch cable as pins1, 2, 3 and 6 may not come into contact with the
RJ45 connector due to safety reasons. The connection cable (2m) to the battery can be ordered from MOBOTIX.
1. Connect the camera's Ethernet patch cable, or that of the PoE device that is to be supplied, to the "Camera"
connector of the blue adapter.
2. Connect the "LAN/Power" connector of the adapter to the Ethernet connector of the switch/router or the
Ethernet socket.
3. Plug the RJ45 connector of the power supply unit/battery into the "PC/Power" connector of the adapter.

Status LED On The Adapter (Primarily For Battery Operation)
An LED light, which indicates the status of the adapter's power supply based on their color, is located on
the upper side of the blue adapter. This is especially important during battery operation. The LED is green
when the input voltage is 16volts or higher. This indicates a maximum PoE output rating of 12.95watts (all
PoE classes and devices). If the LED is orange, only class 1 and 2 PoE devices can be supplied (a max. of
6.49watts; for example, a MOBOTIX camera with and without USB devices). A red status LED indicates low
voltage, for example, the battery is almost empty. The device is permanently disabled for total discharge
protection of the battery at less than 10volts.
The power supply of the MX-NPA-PoE Set operates at an input voltage of 100V to 240V. The "INT" set includes
four interchangeable power supply adapter plugs so that the device can be operated in the dierent power
outlet systems around the world. The individual power supply adapter plugs are packaged in dierently colored
foil bags designed to protect them from dirt and moisture (suitable for storage between -40°C and +70°C,
-40°F and 158°F).
1. Remove the desired adapter from the packaging (see Delivered Parts).
2. Push down the adapter plug part on the
power supply unit so that the four guides
of the adapter fit securely into the guides
on the bottom of the power supply unit.
3. Push the adapter in the direction indicated by the arrows until it audibly
clicks into place. You can now use the power supply unit.
4. To exchange the adapter, use your finger to press down the button on
the power supply unit. At the same time, use your other hand to pull the
adapter up and away from the power supply unit.
Battery Operation Of A MOBOTIX Camera: Operating Time
A modern MOBOTIX network camera (e.g., D24/Q24) has a power consumption of only 3watts during active
operation. Therefore, cameras can be supplied with power using battery sources of 12V and higher. The
operating time is dependent upon the voltage (V) and the ampere hour value (Ah) of the battery. For example,
a car battery with 70Ah can supply a device that requires 70A for an hour under ideal conditions (e.g., ambient
temperature) before it is empty. The lower the power consumption of the supplied device and the higher the
capacity of the battery, the longer the operating time.
The following values apply to a MOBOTIX D24/Q24 camera. Note that in practice, these values may change
as a result of dierent environmental conditions:
Battery Voltage/AhAvg. Power Consumption Q24/D24Avg. Operating Time (100% Charge)
12V/70Ah0.25A280h (> 11 days)
24V/70Ah0.12A583h (> 24 days)
42V/70Ah0.07A1,000h (> 41 days)
Hint: For a new battery with 70Ah, the voltage value corresponds to the operating time measured in days. In
practice, you should expect half the operating time indicated here.
Power over Ethernet (PoE Conforming To IEEE 802.3af)
Power over Ethernet (PoE) is a technology for supplying network-enabled devices with power via an 8-wire
Ethernet cable. The main advantage of Power over Ethernet is that no additional power cable is required, making
Ethernet devices easy to install in hard-to-reach places or in places that are not equipped to handle numerous
cables. This can significantly reduce installation costs, while also increasing the reliability of the connected
devices by providing a central uninterruptible power supply (UPS).
Caution
The maximum length of the Ethernet cable for supplying power is 100 m.
Care And Maintenance
Clean the NPA-PoE Set using a slightly moistened soft cloth, making sure that no liquid is allowed to enter. Never
use aggressive cleaning agents or cleaning agents with abrasive particles (scouring agent). Make sure you
instruct cleaning personnel on how to clean the set. As the set does not have any mechanical moving parts,
regular servicing and maintenance is not required. MOBOTIX recommends, however, that you occasionally
check that the device is functioning both reliably and properly.
Electromagnetic Compatibility (EMC)
Electromagnetic compatibility encompasses all unintentional or intentional malfunctions of electrical or electronic
equipment generated by electrical, magnetic or electromagnetic fields and processes, for example. This includes
interference from currents and voltages. The proof and verification of immunity to interference and a suciently
low level of electromagnetic interference are regulated by EMC directives and EMC standards.
The European EMC Directive defines electromagnetic compatibility as "the ability of a device, equipment or a
system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic
disturbances to anything in that environment."
The MOBOTIX MX-NPA-PoE Set complies with all relevant EMC and safety regulations (see Declaration of
Conformity).
