FAQ:

Q: What is a 24 volt transformer?

A: A 24-volt transformer is typically used as a control device to turn a higher voltage, generally 120 VAC, into a lower working voltage for switches or relays, such as in a furnace thermostat transformer.

Q: What is a capacitor voltage transformer?

A: Capacitor voltage transformer. A capacitor voltage transformer ( CVT or CCVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal, for metering or operating a protective relay.

Q: What is a power supply transformer?

A: A power supply transformer has a large number of turns on its primary coil, which is connected to the high voltage mains supply and a small number of turns on its secondary, to give a low output voltage.
