An isolation transformer has the same input and output voltages.

Isolation Transformer

A transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety.

Input Voltages

The voltages that are applied to the terminals of a device or a circuit.

Output Voltages

The voltages delivered by a device or circuit to its load, often regulated to meet specific requirements for various applications.
