The AC Dimmer is designed to control the alternating current voltage, which can transfer current up to 220V (5A~10A) (TRIAC BTA16 for 600V/4A but we don't recommend up power to this level). In most cases, Dimmer is used to adjust of AC power for lamps or heating elements, it can also be used in fans, pumps, air cleaners, e.t.c. Power part of dimmer is isolated from the control part, to exclude the possibility of high current disruption to a microcontroller.
The logical level is tolerant to 5V and 3.3V, Signal current
>10mA, therefore it can be connected to the microcontroller with 5V and 3.3V level logic.
Up to 600V/16A
