The AC Dimmer (16A / 24A) is a DIY module—not a finished device—that integrates into your project by connecting to a microcontroller. It is designed for medium-power applications, providing smooth control of heaters, motors, pumps, and ventilation systems, making it ideal for home automation and industrial projects.
Reliable Performance & Efficient Cooling
- The 16A model includes a passive heatsink for heat dissipation.
Flexible Control & Automation
With our detailed documentation and tutorials, you can easily integrate the dimmer into your automation setup. Possible use cases include:
- Smart motor control – Adjust the speed of pumps, compressors, or ventilation systems.
- Home automation integration – Connect to Home Assistant via ESPHome or use Tasmota for cloud-based control.
- Energy efficiency – Program schedules to optimize power consumption and reduce electricity costs.
Easy Microcontroller Integration
The dimmer is designed with electrical isolation, ensuring safe operation with microcontrollers. It supports both 5V and 3.3V logic levels, making it compatible with Arduino, ESP32, and other platforms. The rbdimmerESP32.h library simplifies control, handling timing and interrupts for precise voltage regulation.
Whether you're working on home automation, industrial control, or custom automation projects, our comprehensive guides and support resources will help you integrate and optimize the dimmer for your needs.
