EMTest VDS 200Q – Four Quadrant Battery supply simulator and DC voltage source

The VDS 200Q series is used to simulate the various battery supply waveforms recommended by international standards and by car manufacturer requirements. Especially the manufacturer requirements are an important area covered by the VDS 200Q series as there is a large variety of requirements. Secondly, the VDS 200Q series serve as powerful DC voltage supplies for the DUT during the tests with automotive transients. The VDS 200Q series covers all three supply voltage categories (42 V, 24 V and 12 V). Their current capability ranges up to 100 A depending on the model and your application.

Best to simulate battery supply waveforms

The VDS 200Q is specifically designed to cope with almost every requirement of international and national as well as car manufacturer standards world-wide. Its integrated DC amplifier with a frequency range up to 250 kHz allows to generate dips and drops, short interruptions and many kind of voltage variation representing various phenomena being measured on a wiring harness.
The VDS 200Q Series battery simulators are all four quadrant bipolar amplifiers able to absorb energy fed back from the DUT up to nominal current.
The VDS 200Q offers the QuickStart with parameters being adjustable during test to evaluate the susceptibility level of a DUT. Pulse 4 and 2b as per ISO 7637-2 and many more car manufacturer specific waveforms are pre-programmed. Together with an external signal generator (e.g. AutoWave) the VDS 200Q can generate most complex waveforms.

iso.control Software for control and documentation

Outstanding user convenience, clearly structured windows and operation features and the EM TEST standards library along with the flexibility to generate user specific test sequences very easily are the main features of iso.control software. The software is automatically configured according to the connected EM TEST generators. iso.control software covers international/national standards and most of the manufacturer standards and is continuously updated. Extensive reporting capabilities help the user to create test reports that meet international requirements.
iso.control is supported by Windows 2000, Windows XP, Windows Vista, Windows 7 and Windows 8. Remote control is achieved either via USB or GPIB. iso.control supports a wide range of GPIB cards of National Instruments.
