Digatron EVT-IGBT

Test device for battery packs of up to 1,000 volts

The Digatron EVT-IGBT was developed to test high-voltage battery packs (e.g. for electric vehicles) with up to 80kW per power element. Its unique modularity enables stand-alone operation or the parallel connection of several power elements – for increased output. The device is equipped with IGBT technology and is ideal for fast load changes and simulation of dynamic driving profiles.

Perfect for high demands

IGBT technology means fast load changes, and simulation of driving cycles present no challenge for the EVT.

 

High energy efficiency

All power elements feature IGBT power amplifiers and bidirectional power units with full sine wave grid regeneration.

 

Space-saving

Thanks to its compact design, the Digatron EVT-IGBT requires little space and fits comfortably through door frames.

 

Parallel connection of circuits

Several power elements can be connected in parallel to increase the current and power accordingly. It is also possible to link several test stations.

 

Scalable

The modular construction, including all winding material, allows a system to be expanded by the addition of more modules for higher current and power.

 

One device, two functions

We can supply the EVT as bivalent on request, with which the system can also be operated as a battery emulator (BE mode).
