-48V is used in the telecommunication equipment. The source of the -48V is a bank backup batteries that are always kept charged in the event of power loss. The typical range of voltage is -36V to -60V in this application. Why negative voltage is used is probably tradition as the modern power supplies that use this voltage are isolated and run the same as long as the positive terminal is 48V above the negative terminal.

Up grade 36 volt golf cart to 48 volts?
You will have to change the cart motor to one that operates on 48 volts DC and then add one more 12 volt battery (identical to the exsisting) in series with the batteries that are in the cart now.
Can a ge 36volt motor be run on 48 volts?
The 36 volt motor will over heat (depending on the load of the motor)on 48 volts and melt the copper inside the motor you can rewind the copper inside to cope with the extra 12 volts.My answer would be not to try it as i have and it totaly melted the copper inside.
How many volts is used in toaster?
In the United States toasters run on 120 volts.
Holophane ballast re400mh48hrw how do i wire them and are they 120 or 220?
On your model number the figures after 400MH are the voltages for that ballast. A 40 represents 240 volts, 12 represents 120 volts and yours 48 represents 480 volts. Looks like this is a industrial fixture and not meant for residential use.
How do you use volts?
well it is measuring the amount of electricity energy used
Why do you have to have a converter or adapter in Europe with American electronics?
In Europe the voltage is different, it is 220 volts, where as in the U.S. the voltage for electronics is 110 volts. That is why you need the converter so that you do not ruin your electronics.
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 negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
What is the voltage of a telephone line?
48 VOLTS
Why plus 24 volt is used for telecom equipments?
+24 volts is not normally used for telecom equipment. -48 volts is the usual value. 48 was chosen as a compromise between safety and voltage/power efficiency. Minus was chosen over plus to manage corrosion effects of cabling in underground installations.
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.
What can a 48 volt power supply be used for?
A lot of commercial telecommunications equipment runs on 48 volts. There are also relays that use 48 volts. I'm sure there are many other uses for this. I'm not aware of any in a typical house, if that's what you're looking for. Perhaps certain water softeners, sprinkler systems, etc. run on 48, but the ones I've seen usually run on 12.
How do you get alcohol out of electronics?
Put it in a bag of rice for 48 hours.
How many lead acid cell batteries are needed for 48 volts?
Lead-Acid cells are generally considered to deliver 2 volts, so you'd need 24 cells to get 48 volt. Easiest way of doing that would be to use two 24V batteries as used in truck and heavy vehicles.
How is trigonometry used in electronics?
Trigonometry is used effectively in electronics.
