This circuit does more than an ordinary running light : it not only runs in both directions, but it also flashes with two groups of lamps (flip-flop) and with all the lamps at the same time. The four light effects follow each other automatically.
Specifications:
4 triac outputs: max. 2A each (400W at 220V or 200W at 110V).
Can be synchronised to mains or can work asynchronously.
Running speed: adjustable in asynchronous mode, & fixed speed in synchronous mode.
Suppression of radio interference in synchronous mode.
