5.8 Power Supply
The linescanner requires a nominal 24 VDC power supply, 18 VDC minimum. To insure that sufficient voltage is
supplied to the linescanner, it is necessary to define the gage and the length of the power cable to determine the
resistance and the voltage drop. The maximum current draw of the linescanner is 1 A.
The following table shows typical parameters from shielded 2 wire copper cables and the maximum recommended
cable length.

The linescanner is equipped with an electronic fuse to prevent damage from voltage spikes greater than 36 V on
power or signal lines. If the fuse circuit switches the power off, disconnect the power line for several seconds and
turn power on again.
Power supply cables offered by the manufacturer can be found as electrical accessories, see section 7.7
