โมดูลหรี่ไฟ AC (AC Dimmer) ใช้ควบคุมแรงดันไฟ AC 110V/220V 50/60Hz
รองรับสัญญาณควบคุมด้วย Logic 3.3V/5V จาก Arduino, ESP8266, ESP32, STM32
ใช้ ไทรแอก BTA16-600B + Optoisolator MOC3042M แบบ Zero-Cross
เหมาะสำหรับหรี่ไฟ หรี่มอเตอร์ พัดลม ปั๊มน้ำ หรือเครื่องมือไฟฟ้า
ให้เอฟเฟกต์ไฟหรี่ขึ้นลงนุ่มนวล สวยงามสำหรับ Smart Home

 

This is an AC Dimmer Module designed to control the AC voltage applied to a load such as lamps, motors, pumps, or power tools. It uses a Thyristor BTA16-600B and a Zero-Cross Optoisolator MOC3042M, making it compatible with 3.3V/5V logic control (Arduino, ESP8266, ESP32, STM32).

Features:

  • Supports AC 50Hz/60Hz at 110V or 220V

  • Control via microcontroller (PWM / trigger signal)

  • Zero-Cross detection for smooth dimming

  • Applications: light dimming, fan speed control, motor soft-start, smart home automation

Control Methods:

  • Leading Edge Phase Control (Triac Dimming) → Common in fan regulators and light dimmers

  • Pulse Skip Modulation (PSM) → Passes or skips full sinewave cycles. Not recommended for lamps (may flicker), but usable for some motor or resistive loads.
    ⚠️ Important: Always skip/pass full sine cycles, never half-wave, to avoid DC bias on AC loads.

How it Works:

  • The module detects AC zero crossing via optocoupler.

  • Each zero-cross event can be used by a microcontroller interrupt.

  • Software then determines when to fire the triac, controlling the effective voltage delivered.

  • This allows smooth dimming and prevents abrupt flickering.

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
