AC power Dimmer module 4A-400V
2.29$
2.29$
The AC Dimmer is designed to regulate alternating current (AC) voltage, capable of handling up to 4A and 400V. It is ideal for switching on and off various devices like lamps, heating elements, fans, pumps, and air purifiers. Although it can manage a wide range of applications, we recommend operating it below the maximum capacity for long-term durability.
Dimmers are becoming increasingly popular in smart home systems for smoothly adjusting light brightness. For instance, lights can gradually turn on or off, creating a comfortable ambiance. This dimmer works well with filament lamps and performs effectively with medium to high-brightness LED lamps. However, it is not compatible with fluorescent (gas discharge) lamps.
The dimmer’s power section is isolated from the control section, ensuring that high currents do not disrupt the microcontroller. It supports both 5V and 3.3V logic levels, making it simple to connect to various microcontrollers.
For Arduino applications, the dimmer can be controlled via the RBDDimmer.h library, which uses external and process time interrupts. This simplifies coding and allows multiple dimmers to be operated from a single microcontroller. The RBDDimmer.h library and example codes are available for download from the “Documents” section or GitHub. Our library is regularly updated, so subscribing to our newsletter or checking the website for updates is recommended.
The dimmer connects to Arduino using two digital pins: one (Zero) for detecting Phase Null of the AC and triggering interrupt signals, and the other (DIM/PSM) for adjusting current. The Zero pin must be connected 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.

The product does not match the photo. The Neutre connector has disappeared and a red wheel wire of poor quality has been replaced. I am not satisfied at all.

Hello,
Fast delivery.
Unfortunately, none of the 2 Dadders work.
However, I respected all the prescriptions and used the manufacturer’s software.
What to do?
Thank you for your answer.
