Description

The NT1 Power Management Module COMBI/F3 is a comprehensive solution for ISDN-NT1 (Network Termination Basic Access NTBA) equipment, combining both AC-DC and DC-DC functions.

The GS-COMBI/F3 provide the NTBA with all necessary supply voltages as well as control signals to operate in the different operating modes, typically the Normal Power Mode (NPM) and Restricted Power Mode (RPM).

Connected to the main, Input 1 (2 poles AC connector) is the AC input power to the COMBI/F3, source of the whole necessary power in normal operating mode, namely in NPM. Input 2 is the DC power source when in RPM, therefore to connect to the UINTERFACE.

COMBIF3 supply 3.3V (out 1) for logics and 40V (out 2) for the S interface both in Normal Power Mode (NPM) and in Restricted Power Mode (RPM).

RPM mode COMBIF3 is the emergency condition that occurs if the mains (AC) input is not available. An internal "relay function" is available to reverse the 40 V output polarity. A third auxiliary output can be used for LEDs
