AC power Embedded Dimmer module 16A-600V

Description

The embedded AC Dimmer is designed to regulate alternating current (AC) voltage, capable of handling currents up to 16A at 600V (using TRIAC BTA16). While it can support high power, we recommend operating below the maximum capacity for optimal performance. This dimmer is ideal for switching on and off high-power devices such as lamps, heating elements, fans, pumps, and air purifiers.

Increasingly popular in smart home systems, the dimmer enables smooth adjustments in light brightness, allowing lights to gradually turn on or off to create a comfortable ambiance. It works best with filament lamps and performs reliably with medium and high-brightness LED lamps, although it may be inconsistent with low-brightness LEDs. Note that fluorescent (gas discharge) lamps are not suitable for dimming.

The power section of the dimmer is isolated from the control section to prevent high currents from interfering with the microcontroller. It is compatible with both 5V and 3.3V logic levels, facilitating easy integration with microcontrollers.

For Arduino applications, the dimmer is controlled via the RBDDimmer.h library, which manages external and process time interrupts. This feature simplifies coding and allows for the control of multiple dimmers from a single microcontroller. The library and example codes can be downloaded from the “Documents” section or GitHub, with regular updates available on our website or through our newsletter.

The dimmer connects to Arduino controllers using two digital pins: one (Zero) for Phase Null detection to trigger interrupt signals, and the other (DIM/PSM) for adjusting current. The Zero pin must connect to specific microcontroller pins depending on the model (e.g., Uno, Nano, Leonardo, or Mega), as it is tied to the microcontroller’s interrupt function.
