COMBI/F3 POWER MANAGEMENT MODULE FOR ISDN NT1 REV. 01 Type Vi Vo Io 195 to 253 Vac and 28 to 115 Vdc out 1:3.3V 100 mA COMBI/F3 out 2:40V 120 mA FEATURE ■ Uko INTERFACE (DC) and MAINS (AC) inputs to enable NPM (Normal Power Mode) and RPM (Restricted Power Mode) CONDITIONS ■ INPUT FILTER TO MEET EMI requirements ■ PEAK INPUT OVERVOLTAGE WITHSTANDING ■ AC INPUT PROTECTION FUSE ■ INPUTS TO OUTPUTS INSULATION ■ 2 INSULATED OUTPUTS: ORDERING NUMBER: GS-COMBI/F3-3.3 Vo1=3.3 V for NT1 logics DESCRIPTION Vo2=40 V for “S” interface AUXILIARY LOGIC OUTPUT TTLCOMPATTIBLE for LED & NPM/RPM MODE indication, share the same ground of Vo1 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. ■ 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: 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). ■ ■ - 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 MTBF: 300 Kh, according to MIL HDBK 217-F ■ Operating Temperature: -10 to +70oC ■ ■ 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 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 October 2003 This is preliminary information on a new product now in development. Details are subject to change without notice. 1/7 COMBI/F3 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 10µA 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. 2/7 COMBI/F3 ELECTRICAL CHARACTERISTICS when in NPM (Tamb=25)C, unless otherwise specified.)
