applications

Isolation transformer according to IEC/EN61558-2-4 for general purpose, e.g. for safe isolation
of devices according to VDE0700/EN60335, or as a distribution transformer to build
TN-netsystems. Useable for potential free net, for test systems or as power-ratio transformers.

description

Three-phase transformer, constructed as an isolation transformer according to EN61558 2-4, built in a housing IP23. It is possible to build each transformer in this family in each vector group. Is no vector group mentioned, we use group Dyn5. (star point can have full load from outside
conductor).
Please have a look at the difference between outside conductor voltage (voltage phase to
phase) and voltage phase to star point at the different vector groups. The metal housings are prepared for mounting on the floor. For the connection of cables, there are PG cable couplings used. For safe and easy transportation, the transformers have crane hooks at the upper side.
For safe and easy transportation, the transformers have crane hooks at the upside.
The block terminals are contact safe according to VBG4. With our impregnation under vaccum,
the transformers have a very low hum-noise.
