Manual Stepped Voltage Stabilizer Circuit Diagram

Then the transformer output is rectified by bridge rectifier.

Manual stepped voltage stabilizer circuit diagram.

If you use 12 0 12 transformer then use 24v relay. Use 500ma to 1 a transformer. The rectifier output voltage is filtered by capacitor. The specialty of this ic is low drop out voltage because of the use of mosfet as internal series pass element.

The basic circuit is a schmitt trigger operating between well defined limits. Comparator circuit figure 5. In this circuit lm324 is used as comparator and indicator. Input voltage circuit the input voltage is generated by a step down transformer is feed to inverting terminal of the op amp as vin.

The output voltage can be programmed using the two resistors r1 and r2. In this circuit there are small changing from the first circuit. Here is another simple circuit of autocut for manual stabilizer. As usual relay voltage is derived from dl and cl and reference voltage is given by d2 and c2.

This is an easy to make dc to dc voltage regulator circuit using the reliable msk5012 ic. 1 due to the potential divider action of resistors rl r2 and preset vrl a voltage depending upon input mains voltage appears at point marked a. 10 ampere adjustable voltage regulator using msk5012. Transformer steps down the ac source voltage to 12v.

You can also check this circuit by connecting with 0 12 transformer with 12v relay. Comparator circuit lm324 are use for the comparator circuit which compares a variable dc voltage which is found by step down voltage 220vac 12vdc of the pdb supply.
