PWM 2A AC Light Dimmer LED 50Hz 60Hz

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

Long-term current 2A / short-term 5A

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

PWR 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.
