A Single Phase Servo Voltage Stabilizer (SVS) is an electrical device designed to automatically maintain a constant voltage level for single-phase electrical equipment. Voltage fluctuations are common in many power supply systems, and they can adversely affect the performance and lifespan of sensitive electrical and electronic equipment. The primary function of a servo voltage stabilizer is to regulate the voltage and ensure that it remains within acceptable limits.
Here are some key features and components of a Single Phase Servo Voltage Stabilizer:
Voltage Sensing:
The stabilizer continuously monitors the input voltage using a voltage sensing mechanism.
Control Circuit:
A control circuit compares the measured voltage with the desired reference voltage.
Auto-Transformer:
The heart of the stabilizer is often an auto-transformer. It adjusts the voltage level based on the feedback from the control circuit.
Servo Motor:
The servo motor is connected to the auto-transformer and adjusts its position to vary the voltage output.
Buck-Boost Transformer:
In some designs, a buck-boost transformer may be used to raise (boost) or lower (buck) the voltage as needed.
Output Voltage Display:
Many stabilizers come equipped with a display that shows the output voltage in real-time.
Protection Mechanisms:
Stabilizers often include protection features such as overvoltage protection, under voltage protection, short circuit protection, and overload protection.
How it Works:
The stabilizer continuously monitors the input voltage.
The control circuit compares the measured voltage with the desired reference voltage.
The servo motor adjusts the position of the auto-transformer to achieve the desired output voltage.
The stabilized voltage is supplied to the connected equipment.
Single Phase Servo Voltage Stabilizers are commonly used in residential, commercial, and industrial applications to protect sensitive electronic equipment, computers, and other devices from voltage fluctuations. They play a crucial role in ensuring the smooth and stable operation of electrical systems.
