Time provided by R1, R2 & C1. To change aflame abundance do not change the amount of R1 and R2: set C1 amount from 100 to 2200?F instead. Best achievement is acquired with C1 = 470 or 1000?F and R4 = 12K or 10K. Because of low consumption, commonly 10 or 20 lamp series-loops, the SCR can be used, for archetype C106D1 (400V 3.2A) or TICP106D (400V 2A), and appropriate that this aftermost accessory P0102D accept TO92 case. For the aegis accessory is affiliated to 230Vac Mains, again in some genitalia of the ambit lath is the accountable of baleful potential! Avoid affecting the ambit back amid in the box and attach a plastic.
