AC Dimmers

Mid-power AC dimmer with real-time current sensing for heaters, fans, pumps, and motors (available in 16A or 24A versions). Built-in high-precision current sensor for accurate real-time power monitoring. Integrated temperature sensor with smart fan control for active thermal management. Smooth AC voltage regulation for fine control, not just basic on/off switching. Dynamic cooling system with intelligent fan speed management based on load temperature. Microcontroller-friendly: supports 5V/3.3V logic levels (Arduino, ESP32, STM32, and more). Direct integration with ESPHome, Tasmota, or custom automation solutions. Advanced control using Arduino libraries rbdimmerESP32 and rbpowerESP32 for energy tracking and system monitoring. Energy management features: real-time monitoring, cost tracking, scheduled operation, and current limiting. Complete electrical isolation between AC load and control electronics for safe integration.

Mid-power AC dimmer for heaters, fans, single-phase motors, and smart home automation (up to 16A or 24A depending on model). Integrated temperature sensor for real-time TRIAC temperature monitoring. Intelligent fan control system: active cooling only when necessary, saving energy and reducing noise. Smooth AC voltage regulation — fine-tuned control, not just simple switching. High-efficiency cooling with a compact heatsink and smart fan activation for extended component life. Fully compatible with Arduino, ESP32, STM32, and other microcontrollers (5V/3.3V logic supported). Ready for ESPHome (Home Assistant), Tasmota, or custom microcontroller firmware projects. Advanced Arduino/ESP32 control with the rbdimmerESP32 librariy. Supports automation scenarios like temperature-based regulation, scheduled operation, and power optimization. Full electrical isolation between high-voltage AC and microcontroller circuits for safe integration.
