  At the electron stretcher facility ELSA electrons are accelerated with a high ramping speed of 6 GeV/s. This leads to strong requirements on the main magnets power supplies. In particular, any synchronization errors directly result in beam tune shifts and, at worst, beam loss. The existing thirty years old control units are now being replaced by new in-house developed versatile microcontroller based ones. These allow the application of arbitrary ramp patterns and actual value acquisition in realtime. With an ethernet interface the ramp patterns can be uploaded directly to the power supplies. The flexible design also allows usage of the module to control other power supplies, e.g. those of the orbit correction magnets. This presentation will give details on the developed hardware design and the performance of the modules compared to the existing ones.
