FAQ:
Q: How much fuel stabilizer do I put in my genergenerator?
A: Generator Support: If you have a 2-stroke or 4-stroke gasoline engine, this fuel stabilizer is made for you. Fuel Treatment: It treats up to 80 gallons of gasoline. Use 1 ounce of fuel stabilizer to treat up to 2.5 gallons of gasoline.
Q: What is the basic principle of voltage stabilizer?
A: Basic Principle of voltage stabilizer to Perform Buck and Boost Operations In a voltage stabilizer, voltage correction from over and under voltage conditions is performed through two essential operations, namely boost and buck operations. These operations can be carried manually by switches or automatically through electronic circuitry.
Q: What is the function of motor in auto transformer stabilizer?
A: But, in case of auto transformer type stabilizers, motors (servo motor) are used along with sliding contact to obtain boost or buck voltages from the auto transformer as it contains only one winding. Voltage stabilizers have become integral part of many electrical appliances of home, industries and commercial systems.
Q: What is the difference between servo stabilizer and auto stabilizer?
A: Some stabilizers use a transformer with taps on winding to provide different voltage corrections while servo stabilizers use an auto transformer to have wide range of correction. To understand this concept, let us consider simple step down transformer of 230/12V rating and its connection with these operations are given below.
