Cordex HP 2.4kW / 3.0kW Modular Switched Mode Rectifier
4.2.15 Controller
The 2.4kW rectifier shelf is designed to operate with the CXCR/CXCP controller (rack/panel) or the Cordex HP
controller. A controller adds the following capabilities to the rectifiers:
• Local and remote communications and monitoring
•
User definable alarms
• Daily logging of events and system statistics
• Load sharing
• Power save
NOTE
The 2.4 kW shelf is also designed to operate without a Cordex controller; however load
balancing among the rectifiers won't be as efficient, particularly at lower input voltages.
4.2.16 Internal CAN bus
A CAN bus is used to transmit all alarm and control functions between the controller and rectifier shelves. Two
CAN serial ports (modular jacks), are located on the left side of the rectifier shelf as viewed from the front.
The CAN bus can be daisy-chained from shelf to shelf (CAN 1 of one shelf to CAN 2 of another). The last shelf is
terminated using a CAN terminator.
