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. The device 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 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
Vo2=40 V for "S" interface AUXILIARY LOGIC OUTPUT TTLCOMPATTIBLE for LED & NPM/RPM MODE indication, share the same ground of Vo1 AUXILIARY LOGIC OUTPUT TTLCOMPATTIBLE for LED & NPM/RPM MODE indication, share the same ground of Vo2 INTERNAL RELAY FUNCTION FOR Vo2 POLARITY REVERSE "S" INTERFACE OUTPUT CHARACTERISTICS: - Peak output of 220 mA for 150 ms - Typical output power 4,5 W - Output filtering to meet ETSI requirements - Hold up time: 20 ms with 4,5 W output power - Continuous short circuit protection - Peak overvoltage withstand: 1KV for 10/700 us transversal U-INTERFACE ACCORDING TO ETR080 S-INTERFACE ACCORDING TO ETS 300 012

driving and RPM/NPM mode acknowledge (Logic output), referred to 3.3 V output and a fourth auxiliary output can be used for LEDs driving and RPM/NPM mode acknowledge (Logic output), referred to 40 V. The logics outputs become 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. 6000 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. 3000 VRMS / 1 min. reinforced insulation is provided between Input 2 and 40 V output. 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 10A max input current when Vi2 is <18 Volts. Th 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.
