Ultra-fast Interrupter (UFI)

LV 124 / LV 148 switching device


The Ultra-Fast Interrupter was designed by WKS Informatik GmbH with the purpose of helping your test setup comply with the strictest LV 124 and LV 148 automotive norm requirements, like E10 and E13. Now available in 2 hardware layouts, for 75A and 125A, it covers a wide range of DUT current needs.

The UFI has the flexibility to be set into various function modes and fit to all customer needs:

  • Every switch follows the input signal up to f < 100kHz
  • Every switch has its own input trigger and can be set independently
  • Every switch complies with the edge steepness and speed defined in the LV 124 / LV 148 test cases
  • Bus interruptions are supported for all standard buses (CAN, LIN, etc.) and BroadR-Reach (Automotive Ethernet)
  • Remotely setable between the 2009 and the 2013 LV124 norms
  • Remotely controllable through the RTStand SignalGeneration device
  • Is delivered with a set of norm resistances for norm compliance tests

Through its control capabilities, the UFI is fully capable of being integrated in the RTStand LV124 fully-automated testing systems, as well as in other test setups, which require very short interruptions of signals.
