Safety Warnings，

1. Please don’t install this controller in lightening, intense magnetic and

high-voltage fields.

2. To reduce the risk of component damage and fire caused by short circuit,

make sure correct connection

3. Always be sure to mount this unit in an area that will allow proper

ventilation to ensure a fitting temperature.

4. Check if the voltage and power adapter suit the controller & if anode or

cathode definition is the same as the controller’s.

5. Don’t connect cables with power on, make sure a correct connection and

no short circuit checked with instrument before power on.

6. Please don’t attempt any repairs yourself; doing so will void your

manufactures warranty.

For update information, kindly please consult with your supplier.

Product Brief

LT-311 multi-functional LED Dim controller is dedicated to control single

color changes (common anode), LED lamp’s brightness and synchronic color

changing effect. Extensively used in all kinds of LED lighting decoration.

If used together with our LT-3060 power amplifier，each can control twice

the quantity of LED lights by every adding one more, which can achieve the

unlimited output power repeating.

The controller has 7 function keys:

ON/OFF、MODE、BRT/ SPEED+、BRT/ SPEED-、DIY1、DIY2、

DIY3

Sign Button Description

ON/OFF

on/off key：start or turn off the controller

At the Off status, press any key to start

the controller

MODE

Mode key: press it to enter into next mode

BRT/ SPEED+

BRT/ SPEED+:

press it at the BRT status to increase the

brightness，

press it at the Speed status to increase the

speed

LT -311 Multi-functional LED Dim Controller V2.0 Page 6 of 9

BRT/ SPEED-

BRT/ SPEED-:

press it at the BRT status to decrease the

brightness，

press it at the Speed status to decrease the

speed

DIY1

DIY1：Press it for 3 seconds，LED flashes

twice，and then remember the current

brightness or color changing effect and

speed, just press it once then enter into

pre-setup status

DIY2

DIY 2：The same as above

DIY3

DIY 3：The same as above

.ⅥConnecting scheme

1. Take single color LED Module as an example as follows

LT -311 Multi-functional LED Dim Controller V2.0 Page 7 of 9

2. Collect to single color high power LED lamps, the controller provides

controlling signals only; the lights need extra power based on the specific

working voltage of the lights. Each controller theoretically can control

unlimited quantity of the lamps.

（The high power lights must have built-in constant PWM current driving

circuit）

.ⅦIf one controller is not enough, you can add a 3060

power amplifier to amplify the output.

Bellow are three common methods of connecting. And the three

methods can be mixed up. If you don’t need the color skipping function,

there only need one in-phase anode wire and one in-phase cathode

wire between the controller and the amplifier.

1、Method One：All amplifiers connected to the main power

LT -311 Multi-functional LED Dim Controller V2.0 Page 8 of 9

2、Method Two：Connect the controller and the amplifier by a method of

“hand in hand”.

3、Method Three：The LED modules are followed by amplifiers in series.

Ⅷ. Exception Handles

Malfunction Causation Settle

No Light

1、No power from plug

2、Power supply

protector works

1、Check the socket

2、Check the malfunction，

re-power on

3、Incorrect connection 3、Check connection

Incorrect color

Amplifier not in

phase

4、Incorrect RGB output

wire connection

4、Re-connect RGB wires

correspondently

8、reduce wire length or use

loop circuit to power on

5、Output wire too long

LED BRT is not

smooth or even 6、Wire diameter too thin

7、Overload beyond

controller capability

9、Calculate the current and

change to a thicker wire

7,Change the power supplier

or add a power amplifier
