30V 1A ic LM317 Variable Regulator
If you want used easy variable regulator power supply voltage 0-30V at current 1.5A max. I am like this circuit, because it is small but very good.
I uesd IC – LM317T it is quality products ic variable regulator,so i like make in other power circuit.
I made use of a 24Vac 1A transformer,The output of the transformer is rectified by diode 1N4002 or equiv ,and smoothed filter using 2200uF capacitors.
The float-voltage measured here for the 24V transformer was 34V-35V,it is unregulated DC voltage.
The VR1 is control output dc voltage 0V(1.25V) to 30V(32V) at 1.5A max all range.
It is advised that you use this ic with a suitable heatsink.
Main Part
– IC1 = IC LM317T or KIA317
D1-D4 = Diode 1N4002 or 1N4004 or 1N4007 x 4
C1 = Capacitors electroly 2,200uF 35V
VR1 = Variable Resistor 5K(B)
Other detail part,Please see in image.

30V Variable Power Supply Using LM317
This 30v variable power supply schema is based on LM317 voltage regulator schema . This LM317 30v variable power supply schema can deliver high current (around 5 amps) and variable output voltage between 1.2 volts, up to 30 volts. The led D3 mounted on pin 6 at lm301 lights in constant current mode .

30V Variable Power Supply Using LM317 Circuit diagram
Current limit can be adjusted using R2 potentiometer and the output voltage can be adjusted from 1.2 volts to 30 volts using R8 potentiometer . Input voltage for this variable power supply must be around 35 volts .For this power supply schema you need to use LM317K schema (in to3 package ) which must be mounted on a heatsink .
