All telephone exchanges use -48V DC Power supply. The negative potential is used to prevent electrolysis deposition at Battery terminals. Telephone normally work with about 30ma current driving a line impedence of about 1600 ohms (to drive about 5KM distance). Hence 30ma*1600 ohms=48 volts.
What else can I help you with?
On many voltage a bts works?
how many volts does a bts uses for it to operate depending on size
How many volts does a bts uses?
By BTS, do you mean Base Transceiver Station? Such equipment can be found in cell phone towers. Usually a BTS runs on 48V DC.
Why bts work on -48DC V?
IN BTS -48V IS USED REASON BEHIND IT IS THAT When interference is occur in voltages it affect only positive pulse not in negative terminal so if we make positive common then no interference occur And we get pure -48 volts without any interference. Another reason is that we can use +48 but the lightning has -ve charge due to attraction all the network may destroy so we use the -48 which repel the lightning that make the network safer from great destruction...
Why be use the -48 volt for bts?
48 is volt scale and negative voltage is used for safety of media, to prevent attanuation and noise.
How many batteries you require to get output of 48 volts?
You need to divide the 48 volts by the voltage produced by a single battery.
Is 100 amps 48 volts DC the same 12 volts DC?
No.
What is the voltage of a telephone line?
48 VOLTS
Why is a rectifier needed for a GSM BTS?
This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation So the main function of this is 1) To convert AC to DC 2) To control overloading
How many volts to run a 48 Volt club car electric motor?
If a 48 Volt club car electric motor requires 48 volts, then it should be given a 48 volt power source, or something close to it. Too many more volts and it may burn out; not enough volts and it may not run or it will try to draw too much power and burn out the power supply.
How many amps do 48watt LED 12 volt lights draw?
To calculate the current draw in amps for a 48-watt LED light at 12 volts, you can use the formula: Amps = Watts / Volts. So, 48 watts / 12 volts equals 4 amps. Therefore, a 48-watt LED light at 12 volts draws 4 amps.
Can 230 Volts rating TV operated on 150 Volts?
It would probably not work on 150 volts. Many televisions can be adjusted to work on 230 v (Europe) or 120 v (USA).
