The maximum current can be increased if we add the power transistors needed.
0 50v power supply schematic.
This electronic project can serve as a your lab power supply to test and power your experiments.
0 50v 1a laboratory power supply.
This is the circuit diagram of 0 60v 0 2a variable power supply.
Simply said it is a power supply that can adjust the output voltage or current.
It also includes a wide range current control feature right from 0 to 10 amps.
Transistor variable power supply 1a 0 30v.
Laboratory power supply transformer used in the power supply circuit with 4 bd249 transistors on the output stage.
I think i may have misread the scheme in the electrical or electronic circuit books.
When the current exceeded tr1 and tr2 will work.
National semiconductor application note.
And there are ic1 is used to control a voltage at out point by adjusting vr1 can adjust voltage between 0 50 volts.
Laboratory type 0 50v 0 4a adjustable power supply circuit a classic design based on the tl081 opamp.
You can build suitable one using lm10 op amp and voltage source ic as shown in the schematic diagram below.
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.
Another excellent capability is that the output voltage will change only by 0 01 if the input voltage fluctuates.
But it still has the same characteristics as a fixed regulated power supply.
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.
Adjustable power supply circuit.
0 50v 3a variable power supply circuit.
What is a variable power supply.
They work together with two transistors tr1 tr2.
It will keep a stable voltage when it has any load.
Single output can be used 2x25vac.
0 30v variable power supply at 3a two resistors r1 and r2 limit the overload current.
With the variable supply feature it is easy to control and deliver voltage and current to the load.
The idea was requested by mr.
Most simple power supplies cant get the output to come down to exactly 0v or 0a.
Here is an adjustable 50v 5a power supply with a variable output from 0v to 50v and adjustable current limiting from 0a to 5a.
Circuit s schematic diagram source.
But in this circuit the differential amplifiers have a negative power supply rail at 3v which can pull the output down to exactly zero.
Of course this circuit used to cover the voltage range from 0 to 60v and current from 0 to 2a.
