APBU-44C(E) overview
The APBU-44C(E) PPCS Branching and Datalogger Unit is used to implement the
parallel connection of multiple ACS800 series inverter or supply modules. The
APBU-44C(E) also contains a datalogger for collecting and storing real-time data
from the module power stages to help fault tracing and analysis.
The APBU-44C(E) is a DIN rail-mountable unit and requires an external 24 V DC
power source.
The APBU-44C(E) is connected in the PPCS fibre optic link between the RDCU
drive control unit and the modules. The APBU-44C has connections for four inverter
or supply modules, while the APBU-44CE has connections for twelve.
