UPS Power Isolation Transformer

The UPS isolation transformer serves as a core component of the UPS system. It provides complete galvanic isolation between the primary and secondary windings via electromagnetic induction and is typically installed at the input, output, or bypass side of the UPS. This transformer fulfills multiple critical functions, including electrical safety assurance, voltage adaptation, power conditioning, mitigation of neutral-to-ground voltage issues, electromagnetic interference suppression, and neutral conductor referencing. As such, it is a standard configuration in traditional line-interactive and online low-frequency UPS systems.

Achieves complete galvanic isolation between the primary and secondary windings, transmitting electrical energy through electromagnetic induction. It effectively eliminates stray currents and fault high-voltage crosstalk paths among the grid, UPS host, and load, thereby extending the service life of the host.

Features high isolation withstand voltage rating and excellent insulation performance, effectively protecting against surges, lightning strikes, and other fault conditions, thereby enhancing the overall safety of the UPS power supply system.
