Power Supply Issues
For safe and reliable operation, the camera input supply must be +12 V to +24 V DC.
The power supply to the camera should be suitably current limited, as per the applied input voltage
of b12 V to +24 V.
Assume a worst-case power consumption of +24 W and a 150% current rating for the breaker or
fuse.
Note:
The camera will not start to draw current until the input supply is above
approximately 10.5 V and 200 msec has elapsed. If the power supply stabilizes in less
than 200 msec, then inrush current will not exceed normal operating current.
It is important to consider how much voltage loss occurs in the power supply cabling to the
camera, particularly if the power cable is long and the supply is operating at +12 V where the
current draw is highest.
Reading the input supply voltage as measured by the camera will give an indication of the supply
drop being experienced.
The camera tolerates “hot” unplugging and plugging.
The camera has been designed to protect against accidental application of an incorrect input
supply, up to reasonable limits.
With the following input power issues, the status LED will be OFF:
•
The camera will protect against the application of voltages above approxi28 V. If
the overvoltage protection threshold is exceeded, then power is turned off to the camera’s
internal circuitry. The power supply must be recycled to recover camera operation. The
input protection circuitry is rated up to an absolute maximum of +30 V. Beyond this
voltage, the camera may be damaged.
•
The camera will also protect against the accidental application of a reverse input supply up
to a maximum of -30 V. Beyond this voltage, the camera may be damaged.
