Circuit Diagram Of 0 30v Regulated Power Supply. Adjustable power supply circuit the lm24 op. This is an adjustable and regulated power supply with stabilized dc voltage between 3v and 30v provided that the consumption does not exceed 3a direct current.
So we need to use all the capacitors which are rated at 50v in the circuit. Its an open circuit. Input voltage 24 26 v ac dc output voltage 0 to 30v output current 10ma 3a.
Lm741 opamp is used for ac voltage stabilization.
The rectified voltage at capacitor c1 is around 4230v 30 volt sqr2 30v 141 4230. 0 110 less than a minute. The current limiting resistor is 033 ohm. Here two zener diodes of 12v and 18v are connected in series which provide a total of 30v at the output.
