Dimmer Dimmer AC

Sharebot Programmable Digital Dimmer The Sharebot programmable digital dimmer is a power module designed for precise control of alternating current (AC) loads, ideal for integration into industrial systems or electronic prototyping projects. The control logic is managed by a dedicated microcontroller (Atmel Tiny85), which enables intelligent and smooth phase-cut management across two outputs.


Technical Specifications:

• Logic Supply: 5V DC via dedicated pin headers.
• Communication Protocol: Serial 9600,n,8,1.
• Power Input: Supports AC 50Hz voltages from 110V to 220V. Max 5A.
• Outputs: 2 modulated channels with single regulation, managed by robust triacs equipped with heat sinks to ensure thermal stability. Max 5A total.
• Safety: Circuit equipped with optocouplers for galvanic isolation between the low-voltage logic and the high-voltage power section.

Hardware Features:

• Connectivity: Professional screw terminal blocks for secure AC input and output (OUT-1, OUT-2) connections.
• User Interface: Integrated Reset (RST) button and status LEDs for immediate power and operational diagnostics.

Main Applications: The module is perfect for dimming adjustable lamps, controlling the speed of small universal motors, or managing the power of heating elements, all via simple serial commands.
