The Optimus 4 Channel AC Dimmer Module is designed to control four Alternating Current (AC) loads. , which can handle a maximum power up to 240VAC 5A . In most cases, the AC Dimmer is used for power ON/OFF of lamps or heating elements and can also be used in fans, pumps, air cleaners, etc.

A microcontroller with 5V and 3.3V Logic Levels can be used to control the module. The RBDDimmer.h library is required if you are controlling using Arduino Development Boards.

Features:

• Operating Voltage - 5V
• Built in Zero-Crossing Detector (ZCD) circuit for phase angle firing applications
• Maximum Power - 240VAC 5A (Recommended current - 3A continuous)
• Compatible with 3.3V and 5V Logic Level Development Boards
