Portable isolation transformers

They are used where the use of separate circuits from the mains is required. They are mainly used in wet tank environments, but also in other difficult conditions and are designed to be compact and easily portable, making it easy to use them in different locations as needed.

Type range: TR 9409/4 to TR 9415/4.

We manufacture portable transformers according to the standard STN EN 61558-2-4.
