FAQ:

Q: What does 120 volt VAC mean?

A: VAC is an electrical voltage in an alternating current circuit. The power system supplying homes and businesses in the United States uses AC 120 V, while in Europe the system uses AC 240 V. This means that in the United States, the power available at a wall outlet is 120-volt, 60-cycle AC power.

Q: What does 120 volts AC mean?

A: 120V is the AC voltage on a single hot wire in your home with respect to neutral (or ground). With resistance in the wiring in your house, this 120V will likely have dropped to 115V by the time it gets to the appliance you are powering.

Q: What is AC stabilizer?

A: Voltage Stabilizer is also called Automatic Voltage Stabilizer or AC Voltage Stabilizer or Voltage Regulator. Actually an automatic voltage stabilizer is designed to automatically maintain a constant voltage level, with protections of equipment against voltage surges, over voltage, under voltage, smoothing impulsive noise.
