DESCRIPTION The NT1 Power Management Module COMBI/E1 is a comprehensive solution for ISDN-NT1 (Network Termination Basic Access NTBA) equipment, combining both AC-DC and DC-DC functions. The GS-COMBI/E1 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/E1, 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 U-INTERFACE. The device supply 3.3V (out 1) for logics and 40 V (out 2) for the S interface both in Normal Power Mode (NPM) and in Restricted Power Mode (RPM). RPM mode 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 driving and RPM/NPM mode acknowledge (Logic output). The Logic output becomes high (+3.3V) when in NPM condition. The converter offers short-circuit protection on both outputs: particularly, short-circuit on 40V output doesn't affect the +3.3V output. Out 1, out 2 and out 3 (Logic output) share the same common return. 3000 VRMS insulation voltage for 60 seconds (reinforced insulation) is provided among input 1 and all outputs. Same reinforced insulation is also provided between Input 1 and Input 2. 2000 VRMS / 1 min. reinforced insulation is provided between input 2 and all outputs. When in NPM mode (AC main supply), the module max. power consumption is <15 VA (apparent power). Input 2 undervoltage lockout offers high impedance in order to have 10 uA max input current when Vi2 is <18 Volts. The design of the module has been conducted using the following reference standards: EN 60950, VDE0878 part 1 class B (EMC), EN55022 class B (emission), EN50 082-1 (immunity) ITU-T I.430, ETS 300 012 and ETR 080 and ETS300 047 (ISDN BASIC ACCESS, Safety and Protection); anyway, please note that no certification processes have been carried out on the module itself.
