1/10 gs-nt1+/df3 february 2003 this is preliminary information on a new product now in development. details are subject to change without notice. feature n combined ac+dc converter for isdn nt1+ application n uo interface (dc) and main (ac) inputs to enable npm (normal power mode) and rpm (restricted power mode) conditions n input filter to meet emc requirements n 5 insulated main outputs n peak input overvoltage withstanding n input fuse on ac main input n inputs to outputs insulation n auxiliary logic output ttl- compatible for npm/rpm mode indication (em signal & green led). 3ma output source current n auxiliary logic output ttl- compatible for u-interface detection (red led. 3ma output source current n internal relay function for v o1 polarity reverse n analog outputs emergency condition programmable via external command, ttl-compatible, 1ma sink current n u-interface according to etr 080 with external capacitor gs-nt1+/df3 2/10 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 (v i2 ). 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 theu-interface v i2 , therefore subject of variation as per local application and reg- ulation. in rpm it is also possible to set a different emergency condition setting high the auxiliary input 3 (an- alog emergency input, v in3 ). in this case pout1 is reduced to 25 mw, voltage level being -40v. the following tables give you details of the various parameters in the 3 different operating modes, namely npm with v i3 low, rpm with v i3 high. availability of the input ac main is also acknowledged by 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 th ac main is missing. the presence of the u is detected by an other auxiliary output (out 7) that is high only when v in2 >34 v dc . the nt1+ pmm provides double insulation (3000 v rms ) between the inputs (1 and 2), and among the input 1 and all the outputs. basic insulation 2000 v dc exist among out 1 and all the other outputs. the other outputs (including the 2 auxiliary outputs) and the input 3, share the same common ground. double insulation (2000 v rms ) is provided among input 2 (dc u) and all outputs. the nt1+ power management module operate in the range -10 to +70 o c, storage temperatures in the range -40 to +85 o c are allowed.
