Rectifier –48 V dc, 750 W and –48 V dc, 1500 W
The Rectifier –48 V dc, 750 W and the Rectifier –48 V dc, 1500 W are
switch-mode rectifiers that converts the single-phase AC source at the input
into an isolated, filtered, and regulated DC power output used to feed the
loads and to charge a positive grounded battery. Each rectifier is equipped
with a cooling fan that is field replaceable; refer to Appendix A for the
ordering part number, and to the “Maintenance” Chapter for the replacement
procedure.
The rectifier requires no adjustments. Under normal operation, operating
parameters of the rectifiers in a system, such as float voltage and temperature
compensation, are entirely set and controlled by the Controller CIP or System
Manager CIP from the moment the system is started-up or rectifiers are
inserted into a working system.
If the controller fails or is removed from a working system, or if the data
communication link is lost between the controller and the rectifiers, the
rectifier(s) will automatically revert to their 52.1 V default value.
Figure 4.4 illustrates the functional diagram of a Rectifier –48 V dc, 750 W or
Rectifier –48 V dc, 1500 W.
