They are also available for wide variety of applications such as dedicated voltage stabilizer for small units like TV, Refrigerator, Microwave ovens to a single huge unit for an entire house hold appliances. Whereas, A wide range Voltage Stabilizer can ensure a stabilized out voltage of 190-240 volt with a 50-55 volt boost buck from an input voltage ranging from 140 volt to 300 volt. A normal range Voltage Stabilizer can ensure a stabilized output voltage of 200-240 volt with 20-35 volt boost-buck from an input voltage feed ranging from 180 volt to 270 volt. They are available in different KVA rating and ranges too. Balanced load models and Unbalanced load models. Three phase Voltage stabilizers are available in two different models i.e. The regulation of desired stabilized output is done by buck and boost method as performed by its internal circuitry. These Voltage Stabilizers may be single phase (Output of 220-230 volt) or three phase (Output of 380/400 volt) as required by the type of application. Thanks to the rising competition and increasing awareness for the safety devices. Both analog and digital automatic Voltage Stabilizers are available from so many manufactures. We can see different types of Voltage Stabilizers available in the market. Even the ships, who have their own internal power supply arrangement in form of Diesel Alternators, are heavily dependent on these AVRs for safety of their equipment. The use of Voltage Stabilizer is not only limited to house/ office equipment which are being fed power supply from outside. Voltage Stabilizer is also known as AVR (Automatic Voltage Regulator). The basic purpose of a Voltage Stabilizer is to protect the electrical/ electronic gadgets (for example – Air conditioning Unit, Refrigerator, TV, etc.) from the probable damage due to Voltage Surge/ fluctuations, Over Voltage and Under Voltage conditions.įig.1 – Different types of Voltage Stabilizers What is a Voltage Stabilizer?Ī Voltage Stabilizer is an electrical device which is used to provide a constant voltage output to a load at its output terminals irrespective of any change/ fluctuation in the input i.e. They also have an ultra fast response to voltage fluctuations and allow their users to adjust the voltage requirements remotely including start/ stop function for the output. They are now fully automatic, intelligent and packed with a lot of additional functions. The latest advancements in technology like Microprocessor chips and Power Electronic Devices have changed the way we see a Voltage Stabilizer. Different types of Voltage stabilizers are available now with different functionality and works. Applications of Voltage Stabilizers have became a need for every home.
