Spare parts

A short circuit or overload can cause a permanent failure in the electronic circuit. For some products, it is economically feasible to replace this part.

Next to the electronics, also the enclosures and plastic components are produced in our own factories. Some of these components can be ordered seperately.

Mechanic switches and contactors are often used in transformer fan speed controllers. In case of failure they can be ordered seperately.

Autotransformers are electrical transformers with one coil and different voltage taps. Via these different voltage taps, the different reduced voltages are available. The single winding of an autotransformer acts both as primary and secondary winding simultaneously. This makes it possible to obtain a smaller and lighter construction compared to classical dual-winding transformers. Autotransformers are integrated in Sentera transformer fan speed controllers for motor speed control in steps via voltage reduction. Sentera has its own production line for autotransformers to guarantee optimal quality.
