DESCRIPTION
The NT1+/INF2 Power Management Module is a
comprehensive solution for ISDN-NT1 "Plus"
(Network Termination Basic Access type Plus)
equipment, combining both AC-DC and DC-DC
functions. This version is suitable for Infineon
ISDN U/S chip set.
The NT1+ Power Management Module (NT1+
PMM) provide the NT1+ equipment with all necessary supply voltages as well as control signals
to operate in the different operating modes, typically the Normal Power Mode (NPM) and the Restricted Power Mode (RPM).
Connected to the main, Input 1 is the AC input
power to the NT1+ PMM, 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.
When the main is available (230 Vac in this version) NT1+ PMM operate in Normal Power Mode,
therefore it supply +40V (output 1) to the S-Interface being the output power 4.5 W. Output 2 delivers 5V (up to 720mW) for the logics and output
3 delivers -22V (up to 900 mW). Out voltage 4 is
-50V with 100 mW output power. Last, output 5
delivers -130V and the output power can reach
peaks of 700 mW.
When the main is missing, the module remains
active but only in Restricted Power Mode (RPM).
The only power source in RPM is the Input 2, the
U-Interface (Vi2). Therefore in RPM the following
condition apply to outputs 1 and 2: output 1 reverses the voltage (it becomes -40V) and the
maximum power Pout is reduced to 420 mW.
P2max is reduced to 450 mW typically, however
the output power available at outputs 2,3,4,5
mainly depend on input power available from the
"U Interface" Vi2, therefore subject of variation as
per local application and regulation.
In RPM it is also possible to set a different "emergency condition" setting HIGH the auxiliary input
3 (analog emergency input, Vin3). In this case
Pout1 is reduced to 25mW, voltage level being
-40V.
The following tables give you details of the various parameters in the 3 different operating
modes, namely NPM, RPM with Vi3 LOW, RPM
with Vi3 HIGH.

Availability of the input AC main is also acknowledged by a specific auxiliary output (out 6, "EM
signal"), a TTL-compatible signal set HIGH (to
logic level "1") when the main is available and
LOW when the AC main is missing.
The presence of the "U" is optionally acknowledged by an other auxiliary output (out 7, RED
LED) that is HIGH only when Vin2 > 40V.
The NT1+ PMM provides double insulation (3000
Vrms) between the inputs (1 and 2), and among
the input 1 and all the outputs. Basic insulation
exists among Out1 and all other outputs. The
other outputs (including the 2 auxiliary outputs)
and the input 3, share the same common ground.
Double insulation (2000 Vrms) is provided among
Input 2 (DC "U") and all outputs.
The NT1+ Power Management Module operate
in the range -10 to +70 oC, storage temperatures
in the range -40 to +85 oC are allowed.
