About Beleeb 20Amp Variable Transformer Auto AC Voltage

There are a lot of common uses and practical applications for variacs. As we mentioned earlier, they’re more portable and more cost-effective than regular AC power supplies, which pretty much makes them a top pick for short-term projects and casual hobbies. variable autotransformercan be used to gradually revive previously dormant electronic equipment. They can also be used to regulate servo motors and control the temperature of ovens and heaters. Voltage adjustment, when used with thermostatic control, provides more uniform heating. You can also use variacs to simulate various voltage and line conditions for experiments, or power electrical equipment designed for voltage that isn’t the typical 120V or 240V supplied domestically. Here are some other applications: Regulating voltage Controlling specified input voltage to rectifier elements to generate variable DC voltages from an AC source Operating electrical equipment—typically motors—at the correct or optimal voltage even with subnormal or higher-than-normal supply Varying step-transformer output voltage by control of input voltage Starting synchronous or induction motors in order to provide 50%-60% of the total voltage to the motor stator during start-up. Correcting voltage in subnormal or over-voltage supplies on 1-phase, 2-phase, or 3-phase circuits Compensating for voltage drops by giving small boosts to the distribution of a cable Controlling AC motors and DC motors operation rectified AC circuits Powering fans and other motors with low starting torque Controlling the brightness/dimness of incandescent lamp circuits Extending lamp life by operating it below rated voltage Calibrating electrical equipment and controls Compensating for appreciable voltage drops at the end of lines where distances run too long (like in rural distribution systems)
