4.3 LASER BARCODE SCANNERS
4.3.1 Supply Capacity When Wiring Directly to AS-I Compatible
Scanners
For direct wiring, power distribution is performed simultaneously for all the scanners.
However all the scanner motors start up slowly so that there is no significant peak current
draw. See the specific scanner manual for consumption data.
The maximum number of same type scanners to be supplied for direct wiring by a single
PWR-480B is shown in the table below and depends on the wiring topology:

The following products are also AS-I compatible:
DS5100, DM3610, SC5000
. In case of
networks using a mix of products, you must calculate the total power consumption so as not
to exceed the limits for the specific topology used. See the specific product reference manual
in the Technical Features chapter for consumption data.
AS-I Single Branch
200 W max
AS-I Double Branch
200 W max per branch
AS-I Triple Branch
480 W max (200 W max per branch)
The power supply unit is connected directly to the scanners via AS-I cabling.
