1.2.2 Supply Capacity When Wiring Directly to Scanners
A general rule to consider is that each scanner requires both peak power and steady state
power.
For direct wiring, power distribution is performed simultaneously for all the scanners. This
means that the PWR must bear the peak power draw of all the scanner motors starting up
together. See the specific scanner manual for consumption data.
PWR-240:
The maximum peak power propagated is 24 V x 15 A = 360 W, while the steady state
(normal) power is 24 V x 10 A = 240 W.
PWR-480:
The maximum peak power propagated is 24 V x 26 A = 624 W, while the steady state
(normal) power is 24 V x 20 A = 480 W.
Due to these limits, the maximum number of scanners to be supplied for direct wiring is:
