AC Dimmer Module, 2 Channel, 3.3V/5V Logic

Overview:
The AC Dimmer Module is a versatile device for controlling alternating current voltage up to 400V/8A. It is ideal for controlling the brightness of lamps, power for heating elements, fans, pumps, and smart home systems.

Features:

• Power Capacity: Up to 400V/8A

• AC Frequency: 50/60 Hz

• TRIAC: BTA16 - 600B

• Isolation: Optocoupler for safety

• Logic Level Compatibility: 3.3V/5V (works with Arduino and similar microcontrollers)

• Zero Point Detection: Used for phase timing control with external interrupts

• Modulation: Supports ON/OFF TRIAC dimming using PWM signal

• Signal Current: Greater than 10mA

• Operating Conditions:

  • Temperature: −20°C to +80°C

  • Humidity: Dry environment only

• Applications: Smoothly dimming lights, controlling power for motors, fans, heaters, and smart home automation systems.

Connection:

• Compatible with Arduino using the RBDdimmer.h library.

• Requires 2 digital pins:

  • Zero: Phase detection for interrupt signal.

  • DIM/PWM: Current dimming control.
