Source: InternetPublisher:ghaytweyhtoo Keywords: flashing lights lanterns Updated: 2020/05/13
It is a four-way flashing light string control with a very simple structure . The circuit device is the SS0702
specially
produced by Sunstare Electronics Co., Ltd. (http://jwww.Sunstare.com) for tree lighting control.
integrated circuit. SS0702 series
is made of MOS process and standard DIP-S package.
The R stabilizing and source are preset in the chip , so no external
voltage stabilizing circuit is needed , only an R, step-down current limiting
and C filtering are enough. II - J.4 is a 4-way control
signal output terminal, which can directly drive the thyristors
VTl - VT-1 (MCR100-8 type is suitable)
to control the colored lights Fl - E4 to make horse racing and flashing.
Adjusting RP changes the oscillation frequency of the oscillator in the chip , so the flow rate of the colorful light string can be adjusted.
