-48 v is given to BTS because in this voltage Noise
generation is minimum.
Because two terminal comes out from the battery and
through red color wire we ground the +ive terminal so that
possibility of noise interference will get zero because noise
occurs only in the +ive terminal that's why we use -ive
voltage in the BTS.

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 do you get -48v DC?
In a 48V DC system you ground the positive to 0V so the live wire will be -48V.
How do you wire -48v dc power and ground to earth?
always think of any supply system so : RED = MOST POSITIVE BLACK = MOST NEGATIVE in a telecom system the -48V supply is refferenced to ground and earth, so the supply wire is NEGATIVE, this means a DC supply most positive signal the RED wire, go to EARTH = ZERO, the BLACK wire is the MOST negative, so in this case it is -48V
Why use power interface unit in telecom?
it is a unit in a BTS i.e. base transreciever system..these bts are installed with towers that are used for mobile communication. The piu consists of a power plant and battery bank. power plant has rectifier to convert ac to dc and battery back up is used in case of power failure.
What is cable size for 48V DC 30 A?
The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html Hope that helps. G.
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 the bts is given a power supply of -48v?
because in this voltage harmonics are not present
What are the voltages used for BTS?
24volt dc
Why BTS operated at -48 Volts?
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 is use of fiu in bts?
FIU use in Bts for large number of channels

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...
What is DRFU and is use in BTS?
DRFU stands for Dynamic Radio Frequency Updating. It is a feature in BTS (Base Transceiver Station) technology that allows for automatic adjustment of radio frequencies based on changing network conditions, such as fluctuating traffic or interference levels. This helps optimize network performance and maintain a high quality of service for users.
Why telecom power supply has 48V dc power supply?
because the termination and relays in side the telecoms penal needs for DC supply to continues the protection equipment and relay and purpose of telecoms
Is phantom power always 48v?
"Phantom Power" in use in the recording industry is ALWAYS 48V. Some types of mics use other types of power like T-power or an internal battery, but this is not "Phantom Power".
