Description

InMojo Digital AC Dimmer Module lite v.2 is ideal for AC voltage controlling applications. This v.2 is a enhanced version of our Digital AC Dimmer Module lite v.1. Module contains a Triac triggering coupled with zero-cross detection mechanism for programming the intensity of incandescent lamps or fan speed controlled through a micro-controller.

Changes from Digital AC Dimmer Module lite v.1
1. Low voltage side and high voltage side is completely isolated and the isolated distance is kept under 8mm
2. 100V/240V support and the heating issue has been significantly fixed using a different R2, R3 resistors
3. Diode bridge now supports up to 400VAC
4. All copper traces are 105um and it can withstand 10A recommended MAX (check here: http://www.desmith.net/NMdS/Electronics/TraceWidth.html) (NOTE: If need higher currents you need to change the TRIAC)
5. 4 mounting holes to mount on a different surface

It can handle Max 1000W (100V) and 2400W (240V) load and maximum voltage rating of 400VAC. Connect the utility power at AC IN connector and intended control device in to LOAD connector. An indicator is provided on-board to test the Triac trigger mechanism. Indicator will be full bright when LOAD is 100% ON state.

All the parts are listed in the schematic diagram except for the TRIAC. This is because typically you can use any TRIAC with the SOT-428 footprint. For your information all our assembled dimmer modules are assembled with BT136S (manufacturer part: 771-BT136S-600F118).

Check our download section below to get our Arduino sample code to connect with Arduino.

Warning:
*** Care should be taken when dealing with AC voltages.

Note:
1. Two versions of the Arduino sample code timing are provided. One is for people living in 50Hz countries, the other is for people living in 60Hz countries. Please download the correct version. Check out the comments given in the code for details.
2. If you need to control higher loads, we accept design alteration depend on your specifications (purchase count 50+ only)

If you have any trouble setting up the provided sample code or need help to setting up with PIC micro-controllers feel free to contact us at tech@inmojo.com
