Voltage stabilizer are the automatic voltage regulating machines which does not include moving part inside it. Static Voltage Stabilizers regulate voltage value in milliseconds with microprocessor controlled digital technology. There are no moving parts inside the device that will worn and require maintenance in time. However, in classic servo motor voltage regulators, there are moving and mechanical friction parts such as motor collectors, variable transformer brushes and brush bearings. These moving parts wear over time and the accumulation of dust in between the parts can cause fault in a short time. In addition, when the machine work continuously under load, transformer surface may become heat and wear and even voltage interruptions occur. In other words, the static stabilizers provide a long term use since the regulation is done electronically
