... Powerex NF and A-Series IGBT modules as long as the total shut-down time does not exceed 10µs. Adjustment of Soft Shutdown Speed As noted above the VLA500-01 provides a soft turn-off when a short circuit is detected in order to help limit the transient voltage surge that occurs when large short circuit currents are interrupted ...
