what is the role of isolation transformer in ups?

An isolation transformer in an uninterruptible power supply (UPS) serves to separate the output power from the input power source, providing electrical isolation. This helps protect sensitive equipment from voltage spikes, surges, and electrical noise. Additionally, it enhances safety by reducing the risk of electric shock and minimizes ground loop issues. Overall, the isolation transformer ensures a stable and clean power supply, crucial for the reliable operation of connected devices.
