Simply said it is a power supply that can adjust the output voltage or current.
Variable dc regulated power supply circuit diagram.
A regulated dc power supply is also known as a linear power supply it is an embedded circuit and consists of various blocks.
The fixed voltage regulator is used to offer fixed voltage at the output terminal and does not depend upon the input voltage supplied.
Usually a potentiometer is used for voltage adjustments.
It will keep a stable voltage when it has any load.
But it still has the same characteristics as a fixed regulated power supply.
Also the important is the overload protection.
What is a variable power supply.
Variable power supply circuit.
A variable power supply is one which facilitates the user to vary and adjust the desired output voltage and output current.
Regulated power supply block diagram.
Transistor variable power supply 1a 0 30v.
Adjustable power supply circuit.
The variable power supply circuit is equipped with an adjustable voltage regulator to adjust the output according to the output.
This regulator is 0 50v variable power supply circuit.
Here is the circuit producing variable voltage power supply designed using fixed voltage regulators.
A regulated power supply converts unregulated ac alternating current to a constant dc direct current a regulated power supply is used to ensure that the output remains constant even if the input changes.
Variable power supply circuit from fixed voltage regulator.
Which you can adjust output voltage in a wide range between 0v to 50v and a current at least 3a.
