0 50v Variable Power Supply Circuit

Of course this circuit used to cover the voltage range from 0 to 60v and current from 0 to 2a.

0 50v variable power supply circuit.

This electronic project can serve as a your lab power supply to test and power your experiments. Laboratory power supply transformer used in the power supply circuit with 4 bd249 transistors on the output stage. Moreover it s equipped with an over load and over current protection features. With the variable supply feature it is easy to control and deliver voltage and current to the load.

0 30v variable power supply at 3a two resistors r1 and r2 limit the overload current. Build a bench top lab power supply that is capable of delivering 0 to 50 volts and 0 to 5 amp or a to the load. They work together with two transistors tr1 tr2. R19 5k for fine adjustable voltage output.

This circuit is better than the above circuit. And there are ic1 is used to control a voltage at out point by adjusting vr1 can adjust voltage between 0 50 volts. And full overload protection. This power supply circuit is highly stabilized that its output voltage will drop only 0 005 even though the load changes from 0 to 100.

Because use ca3140 for control current and voltage output in easily. Another excellent capability is that the output voltage will change only by 0 01 if the input voltage fluctuates. 0 50v 3a variable power supply circuit. The maximum current can be increased if we add the power transistors needed.

Use ic lm723 is a voltage regulator designed primarily for series electronics for you electronics projects atlantis circuit board design electrical circuit diagram electronic kits electronic devices electrical symbols power supply circuit. 0 50v 3a variable power supply 0 30v 0 5a variable supply with current adjustable. Lm317hv 0 60v regulated adjustable variable power supply the design. Single output can be used 2x25vac instead of 50vac transformer.

Laboratory type 0 50v 0 4a adjustable power supply circuit a classic design based on the tl081 opamp. R20 50k for adjustable output voltage. P1 50k for control current. When the current exceeded tr1 and tr2 will work.

The next diagram shows the standard lm317hv 0 60v variable regulated power supply circuit in fact this configuration may be universally applicable to all lm317 lm117 lm338 and lm396 ic family. I think i may have misread the scheme in the electrical or electronic circuit books. 0 30v 5a variable benchtop power supply circuit output voltage 0 30v and current 5a max.
