Power Electronics

Measurement technology for power electronics is the origin of Elsys data acquisition solutions. Originally called “transient recorders”, they are used to measure fast transients when driving electric motors, voltage converters or switching elements.



Evaluation of transients usually requires an automated calculation which isiolates transients in the trace and calculates typical characteristics. This can be done elegantly in the formula editor of the TranAX software.

Current & Voltage

With the help of precision voltage attenuators (example EL-Att3-100), voltages up to 1’000 V can be precisely measured and visualized. Currents can be converted into voltages using current clamps, Rogowski coils or HALL current sensors, and thus measured on the Elsys data acquisition devices.

Event Triggering

Disturbances in power electronics often occur only very sporadically. The Event Controller Recording mode (ECR) enables triggered long-term recordings for transients and disturbances. The concurrent dual mode continuously records the waveforms at a lower sampling rate. Thus, states of other signals before and after the disturbance can be analyzed without generating large data volumes.
