The power supply was requested for investigation and investigated in (b)(6).The power supply shows clear indication of overheating but a burn including the houses did not happen.One capacitor got warmed up, lost its electrolyte that caused a short circuit on the secondary part of the power supply.The higher current led to an additional heat for the capacitor.Finally the capacitor ignited a flame for a short time that caused the pcb to get melded.Other than reported, the fuse reacted and stopped the high current and the upcoming smoke.This is the first case of such a nature reported to drager.More than (b)(4) power supplies are in the market since several years.
