PWM 8 Amps TRIAC MAIN VOLTAGE DIMMER

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 specification :

PCB  dimensions: 50mm x 75mm

Mounting holes diameter: 3.2mm

Distance between   holes: vertical 68mm, horizontal 43mm

Working  voltage 80...240VAC

Peak current up to 8 Apms

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

POWER 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.
