Isolation transformers | Choosing the right transformer
There are 5 main types of transformers. The differences between each transformer are related to the types of applications possible. Current transformers: these are transformers in which the secondary current is proportional to the primary current. They can be used with all low-frequency alternating currents. Power transformers: these are distribution transformers with a voltage of one phase higher than 1,000V. They are used to transport electricity over...

How to choose this product
isolation-transformer

An isolation transformer's sole function is to provide galvanic isolation between circuits.

Applications

An isolation transformer is used to electrically separate two circuits or to alter the neutral ground contact configuration.

Technologies

An isolation transformer is a standard transformer with separated primary and secondary windings possessing a 1:1 transformation ratio. The root mean square output and input voltages are the same. Its engineering takes into account losses related to Joule's laws and voltage drops between the primary and the secondary coils.

How to choose

The voltage and the current passing through the transformer will determine its dimensions.

Advantages

- Perfect isolation
- Choice of grounding configuration
