Why is a starting current limiter needed? When a transformer is energized, an inrush current occurs, which can cause a very high current spike for a short period of time. The magnetizing current can then be 10-20 times greater than the rated current of the transformer. This can cause several problems: – Fuses or earth leakage breakers tripping– Heavy load on switches and contactors– Mechanical hum or stress in the transformer core– Unnecessary wear on … Read More

Terminal blocks are the most common interface for transformers. Now we are taking the next step and replacing the classic screw terminals with Push In terminals. We start with the smaller transformers and then gradually continue with the rest of the range. We are constantly developing our products, and this change is a natural step in that process. But what does PushIn terminal actually mean for you? Easier installation: Faster and smoother installation without the … Read More
