We have been developing and manufacturing transformer switches for research, medical and industrial applications for over 25 years. From simple single-phase transformers to large three-phase transformers, the areas of application for our transformer switching relays are very varied due to the different types of transformers and their different loads. By using the soft switch-on method developed by us, one or more single-phase transformers can be switched on in no-load operation or under load without inrush current.
With our many years of experience in the development and production of transformer starting switches, we are particularly strong in the implementation of customer-specific projects for high demands. Agile project teams, flexible production and a strong customer focus are the basis for fast, reliable and high-quality implementation of your requirements.
For medical devices, our transformer switching relays have the option of half-wave failure detection in accordance with EN 61000-4-11
By using the soft switch-on method developed by us, one or more single-phase transformers can be switched on under no-load or under load, without inrush current. Our product portfolio includes:
For 1-phase transformers up to 32 A rated current
For 1-phase transformers with external actuator
Without housing, compact design
High inrush and special requirements?
For 3-phase transformers up to 50 A rated current
Imagine your transformer is safe to operate and the fuse does not blow despite frequent switching on and off. To make exactly this scenario a reality, we have developed a transformer starting switch that completely avoids the inrush current in your transformer and not just reduces it.
