FAQ:

Q: What is the function of a DC power supply?

A: to convert AC power into a lower voltage DC power to convert AC power into a higher voltage DC power to convert DC power into a lower voltage AC power to convert DC power into a higher voltage AC power Explanation: The power supply converts alternating current (AC) power coming from a wall outlet into direct current (DC) power,which …

Q: How do you convert AC to DC power?

A: The formula for converting AC voltage to DC is: AC = DC/0.636. The same formula may be used to convert DC voltage into AC voltage. AC is short for alternating current and describes an electrical charge that changes direction periodically.

Q: What is variable DC power supply?

A: A variable power supply is one which includes some means for the user to easily adjust the output voltage and sometimes the current. Adjustment is most often accomplished with a potentiometer, but may also be done with an analog control voltage, a digital input, an autotransformer, etc.

Q: What is DC power source?

A: AC Power vs DC Power. Power delivered from an AC source is known as AC power, and power delivered from DC sources are known as DC power. The instantaneous values of current and voltage changes over time in AC power sources while, in DC sources, they remain constant.
