Schaffner NSG5000 EMC Test System for Automotive Electronics
The compact and modular System 5000 offers all the
generators necessary for tests with pulsed interference as well as voltage
variations as called for by ISO and SAE. The established test
specifications for passenger cars together with the new standards for
commercial vehicles published by the ISO, SAE, DIN and other bodies are
fully covered, as are the many company specific standards from larger
vehicle manufacturers. The construction adopted enables trends in the
standards and changing market requirements to be followed consistently
through the introduction of new developments or upgrades to the generator
modules.
This compact mainframe houses the common system components
and accommodates all the standard pulse generators such as the Schaffner
NSG5001, the Schaffner NSG5003 and the Schaffner NSG5005. A high
performance processor controls all the real-time tasks, takes care of
system integrity, assures the monitoring of the EUT path and handles
communication with the Windows-based user interface. Besides the control
unit, the power supply, high voltage unit and control electronics for the
EUT are all housed in a package mounted at the rear of the mainframe. This
modularity provides the flexibility to adapt to changing requirements. The
front of the chassis is available for the insertion of various pulse
generators and for the connection and practical handling of test objects.
Interrupt-free test sequences comprising all types of pulse at one and the
same EUT connector are made possible through the use of a high voltage
pulse bus configuration. An electronic switch to connect and disconnect
the battery supply is incorporated in the NSG 5000.
In its standard configuration, the equipment is rated for
testing objects at up to 30V / 25A dc or 48V / 10A dc. The test rig and
the power sources are protected by built-in, over-current trip switches.
Additional inputs and outputs are located on the rear panel for test
execution control purposes and the monitoring of error signals,
oscilloscope triggers, gate start/stop commands, etc. Larger systems
can be created by installing further generators in an expansion chassis
and these generators are instantly recognized by the software and are
embodied automatically in the system. Overall control is effected via a PC
running under Windows.
