Delay switch circuit with thyristor
Delay switch circuit with thyristorcan control the connect and disconnect of high-power appliances. The delaying accuracy of the Figure (a) depends on regulator. Figure (b) uses two-way diode A9903 or TV503 to replace the tetrode BRY20 in Figure (a). Technical parameters: 60V ± 10%; maximum load resistor RL: 860Ω, the minimum load resistor RL: 100Ω, delay time: 0.3 ~ 3.6S.
