WebThe high speed, mechanically-interlocked grounding switch (i.e. the lower vacuum interrupters) connects the collection circuits automatically to ground. This occurs with a complete switching sequence of less than one cycle (between 12 to 16 milliseconds). WebThe control circuit (11) includes a switch (SW12) for grounding the gate of the MOS transistor (11). The source of the MOS transistor (Q12) is connected to the gate of the MOS transistor (Q11). This construction enables high-speed switching action even if a large current flows through an output transistor. notty asian wood coat rack https://mkaddeshcomunity.com
