Why DC-DC converter is used in telecommunication power supply instead of inverter?
DC-DC conversion offers the advantage of a bifurcated power source. AC can be rectified and filtered to supply power under normal conditions at say, 17VDC fed to a 9VDC regulator to power the circuit. A 12VDC battery can serve as an alternate feed to the circuit for times when the AC source fails -- and it is connected to the same 9VDC regulator. Another benefit of DC-DC conversion is isolation to the circuit from noisy events.
What are the differences between ac servomotor and dc servomotors?
AC servomotors require an alternating current as a power source, meaning they need to be plugged into an outlet, while DC servomotors require a direct current as a power source, meaning they can be run off of battery power.
Can a ac motor produce electricity?
Technically YES. But the source of power in Electric cars being DC through batteries, the motor must be DC and not AC.
Where can I find a Zoombox DVD projector 12 volt dc power supply?
yes
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
How do you charge a supercapacitor?
use a dc power source. preferably an ac/dc power adapter. any dc power source will do.
What is an dc meachine?
it is a machine which operates on the dc power source.
Can I create an ac voltage from a dc power source?
Use an inverter. Most inverters are sold to provide 120/240 volts from a 12 or 24 v power source.
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What are the requirements of dc motor?
You need suitable DC power source to run it.
Will an 12v 3a dc out put power adapter fry up a machine that is 12v 2a dc out put?
Youshould not parallel two DC output adaptors. If you meant to say that the second device needed an input of 12 V at 2 amps then the 12 V at 3 amp adapter will work as a power source.
DC VS AC?
DC is constant in directionAC is reversing in direction
How do you connect a DC refrigerator to AC power source?
you dont
what kind of power source will this need?
This item uses an AC/DC power adapter
A power source can deliver what two types of current?
Power supplies can supply AC or DC current.
What is typical source of ac power?
* Coal burning power stations. * The electricity grid. * The power outlet on your wall.
