Datasheet Other1
The EM Test VDS 200B Voltage Drop Simulator is a low frequency amplifier. It simulates the battery power supply of a vehicle and complex power supply distortions in the power range up to 900W. A lot of different waveforms are integrated as standard such as pulse 2b and pulse 4 required in ISO 7637.

Controlled by the AutoWave generator the VDS 200B can be used for the generation of most complex manufacturer and user specific waveforms. The VDS 200B can be used as an individual instrument or in combination with all other generators of the series 200.
