Schematic diagram
The schematic diagram of the small light dimmer is shown in
connected in series with the board, as previously described in
connected to the board, but there is a connector available for greater flexibility. The
maximum load power mainly depends on the TRIAC and heatsink used. Power up to 350 W
can be delivered to the load using the ACST67S TRIAC, if there is no heatsink connected. A
heatsink must be used if the power is higher than 350 W. How to connect the heatsink to the
board is mainly a mechanical issue and it is not within the scope of this document to
demonstrate the small light dimmer with a heatsink (the heatsink calculation is in
