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.
