As shown in the figure, it is high-power four-way flashing light string controller using LC182. The LC182 Manifold contains rectifier amplifier, voltage-controlled oscillator and timing pulse divider, when the circuit is energized, the pin ⑥ ⑦ ① and ② appear high level in a cycle, and the circulation rate depends on the voltage-controlled oscillator's oscillation frequency. Changing pin ③ external rescap or changing audio signal from the internal rectifier amplifier input end of pin ⑤, its voltage-controlled oscillation frequency can be adjusted. SSR1 ~ SSR4 can use SP110 solid state relay, and the maximum output current is up to 3A.
