ISS-7650 (Pulse 5a, 5b Generator)

Automotive Transient Surge Simulator Model ISS-7650

Pulse 5a, 5b Generator




  • Pulse 5a and Pulse 5b generating unit
  • A built-in 60V/30A Coupling Network allows independent operation.
  • Equipped with a programmable clip circuit that can produce Pulse 5b clipped waveform in steps of 0.1V without externally attaching a zener diode.*
  • Pulse 5b clipped waveform is pre-eminent in smoothness.
  • Serial or parallel pulse coupling selectable.
  • Pulse repetitions controller provided (30s to 999s and 1 to 999 pulses)


 * The ISO standard requires pulse 5a and 5b have the same value of their td. Due to the effects of the integrated clip circuit, pulse 5b width is different from that of pulse 5a. Pulse 5b is non-compliant with ISO 7637-2 or ISO 16750
