Isolation Transformers

We engineer isolation transformers with separate primary and secondary windings, distinguishing them from an autotransformer where the primary and secondary share a common winding. The use of isolation transformers offers several advantages:

Consistent Control Voltage:

The isolation transformer derives its control voltage from two phases, ensuring a steady and reliable power supply as opposed to relying on a phase and a neutral one.

Protection against Main Line Disturbances:

With the primary winding isolated from the secondary, any disturbances occurring on the main power line will not affect the control voltage, safeguarding sensitive equipment.

Protection from Welding and Lightning:

Isolation transformers protect equipment effectively from disturbances caused by welding operations and lightning strikes, preventing potential damage.

Ultra-Isolation Option:

For highly-sensitive equipment, ultra-isolation transformers are available, providing an extra layer of isolation and shielding against electrical noise and interference.
