AC 220V 2000W (SCR) Dimmer Controller
SCR is generally used in AC power control circuits such as lighting dimmers, AC motor speed controls, heaters, etc. Where main (live) voltage is used for loads of high watts, or often kilowatts need to be adjusted. The aim of AC Controls is to trigger the SCR part way through each AC cycle so that the load current through the SCR is switched off for part of the AC cycle, so restricting the average current flowing through the SCR, and hence the average power delivered to the load.
