CAUTION/DISCLAIMER: In answering this question, I make a basic assessment about the safety of Phantom Power. This is a basic assessment, and I take no responsibility, and this website won't, either, for actions taken following this assessment. DO NOT SHOCK YOURSELF DELIBERATLY UNDER ANY CIRCUMSTANCES. ELECTRIC SHOCK CAN KILL. If you wish to attempt something which could potentially result in shock using phantom power, TAKE ADVICE FROM GOVERNMENT INSTITUTIONS THERE FOR THIS PURPOSE (risk assessment), such as the HSE in Britain (www.hse.gov.UK).
Phantom Power is a 48 volt DC electric supply provided down the two signal cores of an audio balanced cable, usually 1-2mA, but recently up to 10. It is used mainly by the audio industry to power microphones from a sound desk using the signal cable, eliminating the need for a separate supply.
There are two possible definitions of "safe" in the context of this question. The first is risk of electric shock. Arizona State University teaches that 5mA or less is 'safe'. According to this definition, Phantom Power is safe. This is also borne out by many professionals using this technology on a daily basis, and who sometimes get shocked. It is very doubtful it would affect the heart, and probably wouldn't cause burns, either. However, as I have explained above, take normal electrical precautions (disconnect before working on/don't touch two wires) when using such equipment. Remember that Phantom Power uses earth as it's neutral, and thus it is easier to be shocked than most equipment.
The other side to this is whether it is safe to use Phantom Power on equipment not designed to receive it. This issue arises when Phantom Power has to be applied to all channels on an audio mixing console. This is known as Global Phantom Power. In most cases, microphones which don't use Phantom Power aren't affected: Global Phantom Power is a feature on many desks, and something microphone manufacturers take into account. Sometimes, the power supplied by the desk may not be adequate for modern microphones (you may end up with a 1-2mA supply for a 10mA microphone).
However, one note of caution. If you have equipment which can be powered by Phantom Power or by battery, it is advisable to remove the battery when connecting to Phantom Power.

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 do you increase Speed on a Yamaha 48 volt golf cart?
You can increase the speed of an Yamaha 48 volt golf cart by installing a larger motor or more powerful batteries. This will produce more power to the wheels and more speed.
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.
If the voltage in a circuit is 24 volt and the current is 2 A what is the total power in the circuit?
Power = E times I = (24 x 2) = 48 watts
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 connect a MXL 990 microphone to a Mac?
You don't need a mixer. You will need an audio interface (either USB or Firewire) that has phantom power, that is, 48 volt power to power this condener microphone. With the interface connected, you can use this microphone with Garageband or any other recording software that support CoreAudio hardware.
Can 3 ever start volt batteries in series power a 48 volt bicycle motor?
Not well - that combo would only give 36 volts.
How do you increase Speed on a Yamaha 48 volt golf cart?
You can increase the speed of an Yamaha 48 volt golf cart by installing a larger motor or more powerful batteries. This will produce more power to the wheels and more speed.
Can you use a 12 volt battery to charge a 48 volt battery?
No
Can a 36 volt battery charger charge a 48 volt system?
No.
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.
Is 24 volt DC is equal to -48 Volt DC?
No. The value and polarity are different.
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.
I'm a noob to recording so if have a 9-track mixing board do I need a preamp to run a condenser microphone?
A preamp is required for all microphones, and is built in to the mixer if it accepts microphone inputs. The feature required for most condenser microphones is phantom power, a 48 volt signal that is supplied by the mixer to power the electronics inside the microphone. You must use an XLR (three pin) cable to connect the mic to the mixer to provide this power. There will be a Phantom or 48V switch on the mixer to turn this feature on and off.
How long do the charge last from a 48 volt golf cart battery?
No set answer to that. Depends on the power rating of the motor and how hard you're running it.
Where are the positive and negative posts in a 48 volt system?
their are many many types of 48 volt systems you need to show or state more info on your system
