    230 volts flashing lights circuit description

    This article is 230 volts flashing lights circuit description. Master the principle is very effective method is to combine text read schematics. This circuit is intended to serve as a reliable alternative to heat-activated switches for Christmas tree lights flashing. The equipment consists of Q1, Q2 and associated resistors triggered thyristor. Time is determined by R1, R2 and C1. Flash frequency change does not modify R1 and R2 values: set C1 value from 100 years to 2200 μf opposite. Get the best performance with C1 = 470 or 1000μf and R4 = 12 k or 10 k. Due to the low consumption of the normal 10 or 20 light cycle for Christmas (60 Ma @ 230 v lights typically 20 cycles), very small and cheap SCR devices can be used, for example. C106D1 (400 v 3.2 a) or TICP106D (400 v 2 a), finally, the device proposed P0102D TO92 cases. It is absolutely necessary for the proper operation of the door using high sensitive strategic partnership scr. If you can not find these devices can use Triacs opposite. In this case, the circuit operation is more powerful devices. A recommended triac type is everywhere TIC206M (600 v 4 A), but many others can work. WARNING! Device is connected to 230 volt power supply, then the circuit board part by lethal potential! Avoid touching the circuit when plugged and is packaged in a plastic box. Note that although the triac, a diode bridge d1 d4 is necessary in any case.
