Automotive Power Failure Simulator

PFS XXA1 Series

The PFS XXA1 Series Vehicle Power Fault Simulator complies with GMW3172 Clause 9.2.18, LV 124 and VW 80000. Equipped with solid-state semiconductor switches, it limits voltage rise/fall time ≤1 μs for voltage dip and short interruption simulation. Adjustable output impedance faithfully reproduces supply faults: high impedance for open circuit, low impedance for short circuit, with compliant waveforms across all resistive loads.

Operation is manual or via Ethernet and AutoLab software. The DC switch rated up to 80 V, supports 48 V electrical system testing.
