Chapter 4. Electrical Installation
4.1 Operating Voltage and Current
The power to the developer system is supplied by an SFX12V PSU included in the system.
The input specification of the SFX12V PSU is listed in Table 4-1.

Note:
When installing the developer system in vehicle, we recommend using an inverter to convert the DC
power of the vehicle battery/alternator to AC for powering the SFX PSU power supply.
The developer system also sources power to the camera modules with the POC technology via
MATE-AX connectors. Each MATE-AX connector has 4 pins, so a maximum number of 16
cameras can be supported. The POC power output specification for each camera is listed in
Table 4-2.

Note:
The total current of all 16 cameras is limited to 5A even though the current
per camera can be as high as 500mA.
