Automatic Voltage Stabilizer Single / Three phase
Voltage regulation problems account for more than 90% of the power quality problems seen at most sites.The Voltage Stabilizers provide protection against mains power sags, surges and brownouts.It is ideal for geographical regions that are subject to inconsistencies in the mains supply, such as Africa,Asia and certain parts of Europe.Each stabilizer has a wide input voltage tolerance,and has been designed to provide the ultimate reliability in hostile environments,where the quality of the mains supply cannot be guaranteed.
