High-power thyristor expander
SW03-6L uses three independent isolated power supplies as the power supply for six drive outputs. After optical isolation, the input signal is distributed into two DC trigger pulses, which can drive two thyristors separately. The width of the triggering pulse is consistent with the input pulse width, so when triggering high-power thyristors, especially inductive loads, it can ensure that the thyristors have sufficient time and power to hold the current
