COMBI/F3

POWER MANAGEMENT MODULE FOR ISDN NT1

REV. 01

Type

195 to 253

and 28 to

out 1:3.3V 100 mA

out 2:40V 120 mA

COMBI/F3

115 V

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

V =3.3 V for NT1 logics

DESCRIPTION

V =40 V for “S” interface

The NT1 Power Management Module COMBI/F3 is a

comprehensive solution for ISDN-NT1 (Network Ter-

mination Basic Access NTBA) equipment, combining

both AC-DC and DC-DC functions.

■ AUXILIARY LOGIC OUTPUT TTL-

COMPATTIBLE for LED & NPM/RPM MODE

indication, share the same ground of V

■ AUXILIARY LOGIC OUTPUT TTL-

The GS-COMBI/F3 provide the NTBA with all neces-

sary supply voltages as well as control signals to op-

erate in the different operating modes, typically the

Normal Power Mode (NPM) and Restricted Power

Mode (RPM).

COMPATTIBLE for LED & NPM/RPM MODE

indication, share the same ground of V

■ INTERNAL RELAY FUNCTION FOR V

POLARITY REVERSE

Connected to the main, Input 1 (2 poles AC connec-

tor) 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 U-

INTERFACE.

■ “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

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).

- Peak overvoltage withstand: 1KV for 10/700 us

transversal

RPM mode is the emergency condition that occurs if

the mains (AC) input is not available. An internal “re-

lay 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

■ 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 +70 C
