35V adjustable power supply 1.5 A

35V adjustable power supply 1.5 A
One of the most needed instruments in electronics lab is adjustable power supply, allowing you to feed each circuit is tested or constructed for the required voltage and current. The adjustable power supply circuit shown here is just a linear power supply, a bridge rectifier and filter capacitor that it attach series voltage regulator. Furthermore, here was provided by a pair of fixed instruments that allow us to know at any time the voltage given in the output and

DC power supply 3-30V 3-30V 3A stabilized

DC power supply 3-30V 3-30V 3A stabilized
This DC power supply circuit diagram is designed as an additional or as a permanent power supply for all general circuits based on a stable DC voltage between 3 and 30V provided that current consumption does not exceed 3A. Of course, this DC power supply can also be used to other purposes. By replacing the trimmer by a potentiometer, it can even be used as adjustable supply unit. A good quality heatsink must be used.
