Shield dimmer pwm 240VAC Modul dimmer PWM cu Triac BTA16 600B la 240VAC cu trecere prin zero. Ideal pentru constructie IOT. Desi suporta 16A, eu va recomand a nu se depasi 4-8A in stransa corelatie cu temperatura radiatorului nu mai mare de 70-80C Max !!! Product Overview: The AC Dimmer is designed to control the alternating current voltage, which can transfer current 400V (8A). In most cases, Dimmer is used to turning 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 the 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 effective with filament lamps. It s less stable with low brightness 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. 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. Power part of 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. You can download RBDDimmer.h library and a few examples in Documents or on GitHub. We are constantly updating our library, so we recommend to check for the website updates or subscribe to our newsletter. In Arduino, the 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 main code. Which is why you can control multiple Dimmers from one microcontroller. 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. Theory: Dimming can be achieved by Pulse Skip Modulation: Method 1 One or more cycles (sine wave signal) are transferred to the load while following one or several cycles are blocked. Method 2 Partial transference of each sine wave to the load. Method 3 Generation of modulated full sine signal of different frequency up to few hundred Hertz. This method requires specialized powerful AC generators with different modulation. Methods 1 and 2 are the easiest to execute with the help of a Dimmer and program code: in both cases, there is a need of circuit that detects the zero crossing and can control a TRIAC.

The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires. Note: When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan and to solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a high-current system) However,when using the board at currents up to 6A the chips will barely become noticeably warm. d51v al3x r3d Features: Power supply: Max 16V Maximum current rating: 30 A Practical Continuous Current: 14 A Current sensing available to Arduino analog pin MOSFET on-resistance: 19 m (per leg) Maximum PWM frequency: 20 kHz Thermal Shutdown Under voltage and Overvoltage shutdown - - - - - - - - - - - - - - - - - - - - - - - - - ATENTIE !
