Preparation Chapter 5
Use of external DC power supply
Make sure that the output voltage of the external DC power supply meets the rated voltage of the camera before making a connection.
The output current of the external DC power supply should be large enough to provide the connected camera with its total amperage needs with a reasonable margin.
Use the following formula to calculate the total amperage of the camera.
total power consumption ÷ voltage
When the power is turned on, a rush current occurs. If the power supply is insufficient during this time, the camera may be damaged. Therefore, we recommend using an external DC power supply that provides at least twice the total power consumed by the camera and all the devices connected to the unit that power on when the camera powers on (example: viewfinder). The DC cable should be a
When using an external power supply other than the AC adaptor, check the DC IN socket pin information to ensure correct polarity. If a +12 V power supply is accidentally connected to the GND terminal, this could cause a fire or personal injury.

NOTE
•When both the battery and the external DC power supply are connected, power is supplied from the external DC power supply. The battery can be removed or mounted while using an external DC power supply.
•When using an external DC power supply, make sure you turn on the external DC power supply before turning on the
•The light circuit does not operate when power is supplied via the DC IN socket. The light circuit can only operate when power is supplied through the Anton/Bauer battery holder.
