Manual Stepped Voltage Stabilizer Circuit Diagram

Use 500ma to 1 a transformer.

Manual stepped voltage stabilizer circuit diagram.

This is an easy to make dc to dc voltage regulator circuit using the reliable msk5012 ic. If you use 12 0 12 transformer then use 24v relay. Then the transformer output is rectified by bridge rectifier. Here is another simple circuit of autocut for manual stabilizer.

The output voltage can be programmed using the two resistors r1 and r2. The rectifier output voltage is filtered by capacitor. In this circuit lm324 is used as comparator and indicator. In this circuit there are small changing from the first circuit.

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 basic circuit is a schmitt trigger operating between well defined limits. Comparator circuit figure 5. 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.

You can also check this circuit by connecting with 0 12 transformer with 12v relay. Transformer steps down the ac source voltage to 12v. Our ebooks you can read manual stabilizer circuit diagram online or save it on your computer. The specialty of this ic is low drop out voltage because of the use of mosfet as internal series pass element.

10 ampere adjustable voltage regulator using msk5012. As usual relay voltage is derived from dl and cl and reference voltage is given by d2 and c2.
