Description: A Voltage stabilizer is also known as Automatic Voltage Regulator (AVR). These are electrical appliances that deliver a constant voltage to the output terminal, even if the input/supply voltage is varying. They protect electrical equipment from power surges that could damage them or cause an interruption in the workflow. The stabilizer voltage stays between the 220V-230V and 380V-400 range for single-phase and three-phase, respectively. Its internal circuitry performs the buck and boosts operations to regulate to maintain the voltage at this range.Types of AVRs include manual, automatic, servo-controlled and static stabilizers. Voltage stabilizers are necessary to prevent long effects of unstable power supply to devices even if they support a wide range of voltages. If unregulated, both low and high voltage fluctuations result in permanent damage, reduced device lifespan, malfunctioning and insulation damage. The type of voltage stabilizer that one needs depends on factors such as appliance voltage, installation area’s power fluctuations, type of stabilizer and its over-voltage or under-voltage cut-off. Get the best selection of voltage stabilizers for home and industrial use. MRO Supply is dedicated to providing a large range of voltage regulators for stable power supply.
