NT1+/UR2
DESCRIPTION The NT1+/UR2 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. 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 -21V (up to 900 mW). Out voltage 4 is -50V with 100 mW output power. Last, output 5 delivers -150V 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. An auxiliary output (Output RELAY, pin 11) is available for U-INTERFACE voltage level acknowledge, the threshold level being fixed at 85 V. When U-INTERFACE voltage level is below 85 V, a POTS is connected therefore the auxiliary relay output is LOW. Vice versa, this output goes HIGH when U is higher than 85V (ISDN line card). The presence of the "U" is detected by an other auxiliary output (out 7) that is HIGH only when Vin2 >34V. 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.
