Field of application

Isolation transformer conform to IEC/EN61558-2-4 for general purpose, e.g. as safe isolation of devices conform to VDE0700/EN60335, or as distribution transformer to build TN-net systems. Suitable for potentialfree nets, test systems and as power-ratio transformer.

Description

Three-phase transformer, built as isolation trasnformer conform to EN61558-2-4 in a housing IP 23. Basically this type size can be built in any vector group. If there is no vector group given, we will use Dyn5 by default.
Please consider the difference between outside conductor voltage and phase voltage to star point at the different vector groups.
For a safe and easy transport, the transformers have crane hooks at the upper side.
The used block terminals are shock proof conform to VBG4. A vacuum varnishing makes a low
hum-noise possible.
