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 24 volt power supply?
A: The 24 Volt Power Supply is a outgrowth of the 12V common battery voltage. A 24 Volt supply provides more available power for a moderate increase in size. With the advent of solid state equipment the move to more powerful consumer devices for use in home and office required more powerful supplies.
Q: What is transformer power supply?
A: Power Transformer. A power transformer is the component in a power supply that ‘transforms’ or converts the input utility voltage to the voltage required (which can be either higher or lower than the wall outlet voltage). The output voltage it provides is isolated from the input; there is no connection between them.
