Electrical Power: Installing The Power Supply
The power supply of the MX-NPA-PoE Set operates at an input voltage of 100 V to 240 V. The "INT" set includes
four interchangeable power supply adapter plugs so that the device can be operated in the different power
outlet systems around the world. The individual power supply adapter plugs are packaged in differently 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 3 watts during active
operation. Therefore, cameras can be supplied with power using battery sources of 12 V 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 70 Ah can supply a device that requires 70 A 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 different environmental conditions:
Battery Voltage/Ah
Avg. Power Consumption Q24/D24
Avg. Operating Time (100% Charge)
12 V/70 Ah
0.25 A
280 h (> 11 days)
24 V/70 Ah
0.12 A
583 h (> 24 days)
42 V/70 Ah
0.07 A
1,000 h (> 41 days)
Hint: For a new battery with 70 Ah, the voltage value corresponds to the operating time measured in days. In
practice, you should expect half the operating time indicated here.
