25A Switch Mode Rectifier  NT5C06B / C Installation and User Manual
Appendix A: NT5C10BF-1 and NT5C10BP
Purpose
This appendix provides additional information about the NT5C10BF-1
(brown) and NT5C10BP (grey).
Application
The NT5C10BF-1 and NT5C10BP power shelves are used in the FTIP and
FTOP application. This power shelf provides housing for two MPR15E
rectifiers plus one 50 A LVD, FTIP application, or three MPR25EX
rectifiers, FTOP application. In both applications the rectifier in the center
will be wired for standby operation (standby means that this rectifier will be
inhibited under normal operation and will become active when another
rectifier in the same power shelf issues an RFA).
FTIP application
The MPR15E (NT5C06CB/CD) rectifier is used in this application. Two
rectifiers maximum can be used in each system, plus one 50 A LVD. The
main rectifier is active and carries the load, and the standby is inhibited. It
will be activated upon removal or failure of the main rectifier (hot standby
model).
During transfer from a failed “MAIN” unit to a “STANDBY” unit the load
current will be supplied by the backup batteries. The standby unit will
provide the required current within 10 seconds.
