Simulator for automotive cranking pulses evaluation module


Order now


The Cranking simulator generates preprogrammed cranking pulses, resembling typical pulse as seen on Car-Battery during cranking (e.g. during start-stop operation). Other pulses can be configured via source-code change, which makes it applicable for any supply-voltage profile in the range of 2.18V.

This tool can be used to verify system-performance like the reaction of buck-boost topologies to such pulses on their input.

  • 3 pre-programmed typical cranking pulses
  • Other pulses individually programmable via firmware-change
  • up to 50W output power
  • Adjustable repetition rate
  • Continuous or single-shot operation
