CEDS Converters

Generally, we offer three types of converters: frequency, servo and universal converters. But we regard this more as a starting point, as with our different modules and configuration options we offer you a converter technology precisely geared to your individual requirements.

Frequency converters

In general, converters can generate a voltage from an alternating current with a certain frequency corresponding precisely to the desired frequency. They are often used to drive an asynchronous motor. The simplest form of converting voltage is the frequency converter. It controls the speed without any feedback. 

Servo converters

Servo converters, on the other hand operate dynamically. This ensures a high speed accuracy. As usual for servo motors, the specified speed is attained and maintained. The speed can also be quickly changed. To allow other different applications, servo motors have a modular design. A second transducer system can be integrated. 

Universal converters

Universal converters combine the characteristics of frequency and servo converters. They can be operated with a simple speed control or speed feedback. Universal converters operate with a current recuperation, making them particularly energy efficient. In this way, an asynchronous motor can be operated as a generator. The energy generated, for instance, during braking of an electrical locomotive is fed back into the grid and is thus not lost. The same also applies to motors of centrifuges or elevator drives.
