Quality control


Quality warranty

We warrant quality

We offer you a five year warranty.

We wish to ensure that our products are the safest component in your production line. To achieve this, we make certain that the materials we use and our manufacturing process are of the highest standard. Due to our use of premium class insulation materials and our design for longevity we are able to offer you a five-year warranty.

All transformers are manufactured in accordance with the latest VDE-Regulations (VDE 0570/EN 61558 or VDE 0532 / EN 60076)

It must be pointed out that the transformers are insulated in layers. This ensures a dielectric strength of the windings between the layers ensuring longevity. Transformers are stacked alternately. Unlike welded laminated sheet packages, there is less reactive current share as well as reducing the amount of idle loss.

Regarding certification:

Instead of using expensive consultants we have chosen to organise and implement our own manufacturing management and quality control. We prefer our clients to benefit from these cost saving measures.
