Using external DC power supply

  1. Connect the external DC power supply to the <DC IN> terminal on the camera.
  2. Turn on the <POWER> switch of the external DC power supply (if the external DC power supply has a <POWER> switch).
  3. Set the <POWER> switch of the camera to <EXT>.
  • External DC power supply

Connect after making sure that the output voltage of the external DC power supply is compatible with the rated voltage of the camera.

Select an output amperage for the external DC power supply with a margin above the total amperage of the connected devices.

The total amperage of connected devices can be calculated with the following formula.

Total power consumption ÷ voltage

When the power of the camera is turned on, inrush current is generated. An insufficient power supply when turning on the power may lead to failure. It is recommended that you use an external DC power supply that can assure double the capacity of the total power consumption of the camera and connected devices (such as viewfinder) that are turned on by the interlock when the power of the camera is turned on. For the DC cable, use a dual-core shielded cable of AWG18 (nominal cross section area 0.824 mm2) or thicker.
  • Check the pin alignment of the DC output terminal of the external DC power supply and the <DC IN> terminal on the camera, and make sure to correctly connect the polarity.

    Mistakenly connecting the +12 V power supply to the GND terminal may result in a fire or failure.

NOTE

  • When using external DC power supply, be sure to turn on the <POWER> switch of the external DC power supply, and then set the <POWER> switch of the camera to <EXT>. Performing these operations in the opposite order may lead to failure due to the output voltage of the external DC power supply rising too slowly.
  • Even when the camera is connected to the CCU, operation from the CCU and ROP can be performed with the external DC power supply. The performance is affected by the extended distance between this camera and the CCU.
  • When the camera is connected to the CCU while the external DC power supply is used, perform the following.
    • Use the optical fiber multi cable to connect to the CCU.
    • Set [MAIN MENU] → [SYSTEM MODE] → [CABLE CONNECTION] to [FIBER].
