Description
APBU-44C 64669982 power supply ABB ACS800 unit branch
APBU-44C
APBU-44C PPCS branching and datalogger unit is used to implement the parallel connection of multiple grid-side or rotor-side converter modules. The APBU-44C also contains a datalogger for collecting and storing real-time data from the module power stages to help fault tracing and analysis.
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.
