PWM AC Light Dimmer Module 50Hz 60Hz Arduino Raspberry LED Smart Home
AC Phase Control Circuit (Dimming Circuit) / Home Automation, School Projects, Work Related Projects
DIMMING LEVEL CONTROL VIA PWM SIGNAL OR VOLTAGE LEVEL For 50Hz and 60Hz AC Lines
This module is designed to control the intensity of incandescent lamps, AC LED dimmable bulbs, LED Strips, Power of heating elements and AC motor speed through a micro-controller by PWM signal or voltage level.
Device characteristics :
PCB dimensions: 50mm x 75mm
Mounting holes diameter: 3.2mm
Distance between holes: vertical 68mm, horizontal 43mm
Working voltage 80...240VAC
Device power supply - 5V or 3.3V
Compatible for 50Hz and 60Hz AC LINE
Autodetect AC LINE frequency - 50Hz or 60Hz
PWM input signal up to 10kHz
Input voltage level up to VCC (0-3.3V / 0-5V)
50HZ LED - show detected 50Hz AC Line
60HZ LED - show detected 60Hz AC Line
Both LED flashing - when AC Line is not detected
POPWE LED - indicate device power
On-board Snubber circuit for triac protection, when you're controlling inductive load
Low voltage side and high voltage side is completely isolated
Fully compatible with any MCU, Arduino or Raspberry boards
NOT appropriate to change the brightness of fluorescent lamps !!!
To control LED STRIP, diode rectifier must be connected before AC INPUT.
AC LOAD dimming control via firing angle method.
