Custom transformers and inductors
Isolating a network, matching a voltage or filtering a current: we calculate the right transformer or inductor for your installation and mount it in a cabinet with its protection.

The CAUM.ELEC engineering office designs the magnetics for its own equipment and for its customers: core section, number of turns and copper sections, temperature rise, short-circuit voltage. Winding is entrusted to partner transformer makers, while integration, wiring and testing are done in our workshop.

- Cabinet mounting with circuit breakers, bypass and signalling
- Transformers for rectifiers and thyristor chargers
- Smoothing, filter and power factor correction (PFC) inductors
- High-value inductors for special applications
- CAD layout and wiring drawings supplied
