4.1.3 Cordex Rectifier Shelves
A 2500 A power distribution bay has 5 rectifier shelves and a 2000A power distribution bay has 4 rectifier shelves.
Each rectifier shelf can hold up to six Cordex 4 kW rectifier modules or two 12kW/480 rectifier modules.
A Cordex 4.0kW rectifier supplies a nominal output of 74A at 54Vdc and the 12kW/480 rectifier supplies 222A at
54Vdc nominal. Rectifier specifications are included in the Cordex rectifier manual included with the system docu-
mentation package.
The controller provides central control of the rectifiers’ output level, load sharing, temperature compensation and
alarm reports. A CAN bus cable is wired or daisy-chained to each rectifier shelf for communication with the Alpha
CXC System Controller.
4.1.4 Rectifier Modules
The rectifier modules are "hot swappable" allowing for quick replacement and easy maintenance of the system. (They
can be inserted or removed from the shelf without removing AC power or shutting down the entire system.)
