The Micro Controller Based Servo Stabilizer is the most important requirements these days. This is needed to attain the load voltage stabilization. It is accessible with the technique of tap-changing transformer and features a relay module in the coupled circuit. Micro Controller Based Servo Stabilizer is incorporated with microcontroller and thus is used to control the switches as well as stabilizing the load voltage. It ensures protection against load current variations and supply voltage disparities. Adjustment in the load voltage can be done easily.
