Description

2811DC2-30

30 Channel WS2811 controlled dimmer for 2 wire, 2 channel LED strings

2 x 3 way pluggable 3.5mm plugs for data in and data out.

20-40V power input. 15A maximum current

2A maximum per output

Channel Outputs
There are 30 channel outputs grouped as 15 pairs of 2 channels. The maximum load per channel is 2 Amps, but the overall limit is 15 Amps. This means that you can’t turn on all 30 outputs with the maximum load. In reality, this should not be a problem as most loads will be less than 2 Amps.

SPI Data Input/Output

The pcb has 2 terminals blocks for getting the SPI / pixel data into and out of the pcb. These are removable screw terminals and the wire that goes into each position is marked on the pcb. The data into the pcb comes in via the D.In terminal and data out to other boards or pixels goes out the D.Out terminals. The 3 terminals are GND, +VE and Data

A DC power supply and a  source of WS281x pixel data is what is required to run this board.

David Duffy of Audio Visual Devices has a page (http://www.da-share.com/circuits/2-wire-led-strings/) that has some information on the 2 wire, 2 channel led strings that this controller is used on. Lytworks lights from Bunnings as well as ones from Big W and other retail stores are mostly going this way.

2 wire, 2 channel led strings can be identified by the fact that there is a multifunction controller either as part of the power supply or inline with the wires from the power supply and from there out to the leds there are only 2 wires.

 

The controllers that this board is designed to replace have a typical appearance like below.

 

 

This style controller comes in numerous different voltages from 5V up to 36V. All 15 strings that get connected to the 2811DC2-30 should be the same voltage (within a few volts). The voltage of the lights/controller can be seen as in the picture below. Lights in the range from about 27V-36V can generally all be ran from a 31V power supply. If all the lights are the same voltage the S200-31 and S400-31 (and the other voltage supplies) are adjustable +/-10%.

 

 

 

The 2811DC2-30 is unsuitable for voltages below 12V.

The 2811DC2-30 is NOT SUITABLE to control the 2 wire Twinkly lights. The Twinkly lights are a brand name and they are a 2 wire pixel. Each led on a Twinkly string of lights can be any colour. The usual control of Twinkly lights is either via an app or a remote control that has a full colour pallette on it.
