How Do Isolation Transformers Work?
The Danger in Your Walls Every day, Americans use numerous electrical devices, from lamps and hairdryers to cell phone chargers and coffee makers. Each and every device is connected to the main voltage in the home. The mains voltage runs at 120 volts and has access to a great deal of current. This current poses great risk to humans, which requires a good deal of safety built into the circuit. This task is accomplished within the circuit in part by the isolation transformer. Isolate the Circuit from the Mains Isolation transformers are built typically with a 1 to 1 ratio. Five volts in is five volts out. The protection comes from the fact that the second coil is not connected to the first, which is connected to mains. As a result, touching a part of the circuit connected to the second coil will not result in a deadly shock. The design of the transformer depends upon the usage that the circuit will draw, typically resulting in larger and heavier transformers needed for higher current app
