APPENDIX C: Internal DC Dual-Source Power Option

C1.0 SPECIFICATIONS - FOR MAGNUM 6K25 FIBER SWITCH Power Supply (Internal, -48VDC Dual-Source, model # Dual-Src-48V)

DC Power Connector: First Source: “A+”, “A-“, 2nd Source “B-“, “B+”

GND:

Terminal for “earth” or ground wire connection to the hub chassis

Input:

Two separate sources, each at 36 - 70 VDC

Power Supply (Internal, 24VDC Dual-Source, model # Dual-Src-24V)

DC Power Connector: First Source: “A+”, “A-“, 2nd Source “B-“, “B+”

GND:

Terminal for “earth” or ground wire connection to the hub chassis

Input:

Two separate sources, each at 20 - 36 VDC

Power Supply (Internal, 125VDC Dual-Source, model # Dual-Src-24V)

DC Power Connector: First Source: “A+”, “A-“, 2nd Source “B-“, “B+”

GND:

Terminal for “earth” or ground wire connection to the hub chassis

Input:

Two separate sources, each at 88 - 150 VDC

With the exception of the dual DC input power connections and the power supply, all specifications and configuration options for the Magnum 6K25 -48VDC, 24VDC and 125VDC models with this Dual-Source option are identical to those listed in the Magnum 6K25 Fiber Switches Installation and User Guide, including Appendix B “Internal DC Power Supply Option”

C2.0 MAGNUM 6K25, with -48VDC, 24VDC and 125VDC Dual-Source option The 6K25-Switch models with the internal -48VDC, 24VDC and 125VDC

Dual-Source power supply are designed for installations where a battery plant is the power source, and where two separate power sources are utilized in order to increase operational uptime and to simplify maintenance.

The functionality of the Magnum 6K25 Switch -48VDC, 24VDC and 125VDC Dual-Source Option units is identical to the standard AC-powered models. Refer to the main sections of this Installation and User Guide for a detailed description of the Magnum 6K25 Switches.

C3.0 DUAL-SOURCE OPTION, THEORY OF OPERATION The Dual-Source DC power

option is designed using diodes inside of the chassis on each DC power input line. A diode is placed in each of the four input lines (behind the four

external power connection terminals) so that power from an external source

can only flow into the unit. This allows the unit to operate whenever DC power is correctly applied to either or both of the two inputs
