LED/Motor radio dimmer/switch for 12V/24V DC voltage This modern RF dimmer is the perfect solution for anyone who wants convenient and flexible control of their 12V to 24V LED lamps or motors. Equipped with a functional wireless remote control, this dimmer allows for continuous dimming – tailored to your individual needs. Thanks to its connection behind the 12V/24V DC LED transformer, the dimmer is suitable for almost all common LED bulbs with a maximum current of 30A. A standout feature of the wireless dimmer is its range of approximately 50 meters. This allows you to conveniently control the lighting from another room without requiring a line of sight. Unlike conventional infrared dimmers, which rely on a direct line of sight, the RF dimmer ensures a reliable connection through walls. The LED dimmer also boasts a practical memory function. When you turn it on again via the wall switch, the last dimming level is automatically restored, so you don't have to adjust the brightness of your lights every time. Of course, the lights can also be turned on or off directly via the remote control, further increasing ease of use. It's important to note that the wireless dimmer is only suitable for 12V/24V DC LED transformers. Halogen transformers with 12V AC are not compatible. The device's compact dimensions (L 48 x W 62 x H 20 mm) allow for easy installation, even in tight spaces. With a maximum power of 360W and a wide operating temperature range of -20 to 70°C, this LED wireless dimmer is both powerful and versatile. Get ready to revolutionize your lighting environment!

AC dimmer for smart home systems The AC Dimmer is a versatile device designed to control AC voltage and allow maximum transfer from 8A to 16A/24A (using the TRIAC BTA16, rated for 600V/16A-24A). However, we do not recommend loading the dimmer to its maximum specification (maximum 10A per channel ). Typically, the dimmer is used to turn the power of lamps or heating elements on and off. It can also be used in applications such as fans, pumps, and air purifiers. Recently, dimmers have become a popular choice for smart home systems. For example, if you want to gently adjust the brightness, a dimmer allows you to switch lamps on and off slowly, creating a pleasant atmosphere. Dimmers are particularly effective with filament lamps. While they are less stable at low brightness levels with LED lamps, they work reliably at moderate and high brightness levels. It's important to note that fluorescent lamps (gas discharge lamps) are not dimmable. ### Technical aspects The dimmer's power section is isolated from the control section to eliminate the possibility of high-current interruptions in the microcontroller. The dimmer's logic level is tolerant to 5V and 3.3V, allowing microcontrollers to be easily connected. The `RBDdimmer.h` library is used to control the dimmer with an Arduino. This library utilizes external interrupts and process time interrupts, simplifying programming and allowing more processing time for the main code. This allows multiple dimmers to be controlled from a single microcontroller. The `RBDDimmer.h` library and some examples can be downloaded from the "Documents" or on GitHub. We continuously update our library, so we recommend checking our website regularly for updates or subscribing to our newsletter. ### Connecting the dimmer The dimmer is connected to the Arduino controller via two digital pins. The first pin is used to initiate the signal at AC phase zero, which triggers the interrupt signal. The second pin (DIM/PSM) controls the dimming current. Please note that the zero pin must be connected to specific microcontroller pins, the assignment of which may vary depending on the model (Uno, Nano, Leonardo, Mega), as these are tied to the microcontroller's interrupts. With all these features and options, the AC dimmer is an excellent choice for anyone who wants flexible and convenient control of their electrical devices.  **Topic: Theory of Dimming by Pulse Skip Modulation** Dimming of light sources and other electrical loads can be achieved in various ways, particularly through pulse-skipping modulation (PWM). In this context, three main methods for implementing dimming are presented. ### Method 1: Cyclic blocking This method involves transmitting one or more cycles of a sine wave signal while blocking the load during subsequent cycles. By selectively controlling the time intervals during which the signal is applied, the effective power to the load is reduced. This technique is relatively simple to implement and requires only a dimmer and appropriate programming code to control the timing of the signal. ### Method 2: Partial transferrence of sine waves This method involves controlling the transmission of portions of each sine wave to the load. Instead of transmitting the entire wave, only a portion of the signal is used, which in turn reduces the average power to the load. This also requires a dimmer, as well as a circuit that detects zero-crossing and is capable of controlling a TRIAC. ### Important NOTE It's important to note that the use of dimmers with LED lights, fluorescent lamps, or other lamps that already have built-in brightness controls is not recommended. These types of lamps are often incompatible with conventional dimmers and may cause unwanted effects or damage. specification power Up to 250V (10A per channel) AC frequency 50/60Hz TRIAC BTA16 - 600B / BTA24 - 600B isolation Optocoupler Logic-level 3.3V/5V/12V Zero point Logic-level Modulation (DIM/PWM) Logic-level ON/OFF TRIAC Signal current > 10mA Environment: For indoor and outdoor use Operating temperatures: − 20 °C to 80 °C Operating humidity: Dry environment only ROHS3 Compliant Scope of delivery : 1 x piece
