EM TEST VDS 200Q-series Voltage Drop Simulator

Description

EM TEST VDS 200Q-series 4-Quadrant Voltage Drop Simulator is used to simulate various battery supply waveforms recommended by ISO and Automotive OEM standards.

The VDS 200Q-series simulators serve as a powerful DC voltage supply for the DUT during the tests with automotive transients. The VDS 200Q-series handles all three supply voltage categories (12 V, 24 V, and 42 V). The current capability ranges up to 100A (depending on the model and your application).

The VDS 200Q has an integrated DC amplifier with a frequency range up to 150 (180) kHz. It allows us to generate dips and drops, short interruptions along with a variety of voltage variations representing various phenomena being measured on a wiring harness.

The VDS 200Q-series are four quadrant bipolar amplifiers capable of absorbing energy fed back from the DUT up to nominal current.
