## Overview

This 2-piece PWM AC Programmable Light Dimmer module offers professional-grade AC voltage control up to 240V/8A, compatible with popular microcontrollers like Arduino and Raspberry Pi. Featuring zero-cross phase control and an integrated heatsink, it ensures smooth dimming and stable operation for lamps, motors, and pumps. Ideal for smart home automation and advanced DIY projects, it comes with a dedicated RBDdimmer.h library for easy coding and multi-dimmer management.

## Description

The AC Dimmer is designed to control the alternating current voltage, which can transfer current up to 240V/8А. In most cases, Dimmer is used to turning the power ON/OFF for lamps or heating elements, it can also be used in fans, pumps, air cleaners, e.t.c. Lately, Dimmer has become an often-used decision for smart home systems. For example, when you need to smoothly change the light brightness. The lamp is slowly turning ON or OFF, creating a comfortable atmosphere. Dimmer works most effectively with filament lamps. It’s less stable with low brightness dimmable LED lamps, but with moderate and high brightness it will perform a solid job. Note that luminescent lamps (gas discharge lamps) do not support dimming. A power of the dimmer is isolated from the control part, to exclude the possibility of high current disruption to a microcontroller. The logical level is tolerant to 5V and 3.3V, therefore it can be connected to the microcontroller with 5V and 3.3V level logic. In Arduino, a dimmer is controlled with RBDdimmer.h library, which uses external interrupts and process time interrupts. It simplifies the code writing and gives more processing time for the main code. This is why you can control multiple Dimmers from one microcontroller. You can download RBDDimmer.h library and a few examples in «Documents» or on GitHub. We are constantly updating our library, so we recommend checking for website updates or subscribe to our newsletter. Dimmer is connected to Arduino controllers via two digital pins. First (Zero) to control the passing of Phase Null of AC, which is used to initiate the interrupt signal. Second (DIM/PSM) to control (dim) current. Note that Zero requires connection to designated microcontroller pins (which are different depending on the model of Uno, Nano, Leonardo, Mega), since it tied to microcontroller interrupts.

## Questions & Answers

**Q: What is the maximum watts at 120volts it can support for hours. Plan to use to control swamp cooler fan speed.**
A: 120 volts * 8 amperes maximum continuous current equals 960 watts. The TRIAC can run at a peak load of 16 amperes , 1,920 watts, but this cannot be sustained for long. If you need higher wattage you’ll either have to run a higher voltage or run the two modules in parallel.
