MEDIUM-POWER AC DIMMING – Smoothly control resistive and inductive AC loads including heaters, single-phase motors, pumps, and ventilation systems. Choose 16A version for moderate loads or 24A for higher power requirements. True phase-angle control delivers precise voltage regulation, not just on/off switching.
OPTIMIZED COOLING FOR EACH VERSION – 16A model features an aluminum heatsink for passive cooling during typical operation. 24A model includes both heatsink and active cooling fan for reliable performance under continuous heavy loads.
ARDUINO & ESP32 COMPATIBLE – Supports both 3.3V and 5V logic levels for direct connection to Arduino, ESP32, STM32, Raspberry Pi, and other microcontrollers. Ready-to-use rbdimmerESP32 library handles timing and interrupts for precise load control.
SMART HOME INTEGRATION – Direct compatibility with ESPHome, Tasmota, and Home Assistant. Build custom automation for motor speed control, scheduled operations, and energy optimization through your preferred smart home platform.
SAFE ISOLATED DESIGN – Complete electrical isolation between high-voltage AC section and low-voltage control circuit protects your microcontroller. Zero-cross detection ensures quiet, reliable operation with minimized electrical interference.
