1.2.3 Supply Capacity When Wiring to SC8000
For the SC8000 Industrial Controller the power consumption is 36 W (+ an additional 68 W
only if the temperature drops below 4 °C).
Power distribution to the scanners is performed by the SC8000 junction box. The SC8000
turns on the scanners one by one in a definite sequence so that simultaneous motor start-up
is avoided. In this way the PWR unit can supply power to a greater number of scanners. 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 when using the
SC8000 Contoller is:

DS8100 and DX8200 scanners have peak power (startup) consumption of 60W.
The power supply unit is connected to the SC8000 external junction box according to the
following diagram (power supply side):
Only two glands on the power supply unit are utilized, AC Line Input and 24 V DC Output.

On the SC8000 Junction Box side, the Low Voltage Output cable must be terminated with
the special connector supplied together with the SC8000 (see the SC8000 Installation
Manual, paragraph 2.3.1).
