Four-Quadrant Voltage Drop Simulator has pre-programmed waveforms.

Press Release Summary:




Used to simulate automotive battery simulation waveform requirements, VDS 200Q Series can source and sink current using programmed voltage in both positive and negative polarities. Amplifier generates dips and drops, short interruptions, and voltage variations to simulate phenomena occurring on vehicle wiring harness. Along with unlimited operation from -15 to +60 V, this DC voltage source offers <10 mΩ source impedance, 150 kHz bandwidth (full signal), and QuickStart feature.



Original Press Release:



Four-quadrant, Bi-polar Operation in New Voltage Drop Simulators from EM Test



VDS 200Q Series simulates numerous automotive battery simulation waveform requirements



EM Test introduces the VDS 200Q Series, a four-quadrant voltage drop simulator that can source and sink current using a programmed voltage in both positive and negative polarities.  The amplifier generates dips and drops, short interruptions and voltage variations to simulate a wide range of phenomena occurring on a vehicle wiring harness.



With unlimited operation from -15V to +60V, this powerful DC voltage source simulates a wide number of battery supply waveforms used by manufacturers in the automotive industry as well as for international quality standards.  Uses include military, avionics and automotive testing environments.



The VDS 200Q Series are fast bipolar amplifiers which operate across all four quadrants that sink as well as source current. This allows the new simulators to drive capacitive loads and absorb energy feedback from the device under test (DUT) up to the nominal current.



A very low source impedance of less than 10mΩ and a high bandwidth of 150kHz (full signal) enables these new sources to support low voltage drop, class-leading inrush current and extremely fast recovery.



The unique QuickStart feature allows parameters to be adjusted during test to evaluate the DUT’s susceptibility level.  And, while many manufacturer-specific waveforms such as pulse 2b (per ISO 7637-2) and pulse 4 (per ISO 16750-2) are pre-programmed, adding an external signal generator allows the VDS 200Q to generate even more complex waveforms.



Test routines are quickly programmed using the intuitive front panel with menus and function keys. The optional ISO control software automatically configures according to the connected EM TEST generators and provides an easy to use interface for accurate control and reporting functions.  The EM TEST standards library is continually updated with the most current international and automotive manufacturers’ standards requirements.
