Nine-channel wireless LED controller TrueSpectrum


Availability:  Out of Stock

* Interface flat cable:

Truespectrum 9-channel LED controller is further development of previous 7-channel LED controller 7chv1.0, is fully compatible with it, and has greatly improved set of features.
New device allows control of up to 9 independent LED light channels using Wi-Fi connection from almost any platform (PC, Mac, Linux, Android, etc.) via Web-browser. New Truespectrum interface allows easy software updates, almost unlimited flexibility of spectrum control and day cycle, and import/export user-created spectrum presets.
The controller supports connectivity of temperature sensor and cooling fan to prevent light fixtures overheat. Each PWM output has 14-bit resolution and higher frequency to allow much wider dimming possibilities, and to prevent flickering and interference while shooting video, or using active 3D glasses for your TV.

Supercapacitor lifetime** controller lifetime

“*” Matching connectors are included
“**” The supercapacitor can keep the clock running for 7-12 days. If the controller board is powered off for a longer period, the real time clock will be reset to the default value and you will have to set the controller date and time anew. 

When purchasing the controller, do not forget to buy the required length of flat interface cable The cable is required for connecting the controller to the drivers.

Connectors and pinouts

Main board is shown with Wi-Fi and controller module removed.

 X1 Power supply connector
The correct polarity is indicated on the figure. The circuit is protected from inverse polarity connection (the controller will not operate if the power is connected wrongly)
 X2 PWM outputs connector
 X3 Temperature sensor connector
 X4 The standard fan connector; upper contact is GND, middle +12V; lower - tachometer sensor. 
Be sure to connect the temperature sensor to the controller, otherwise it will not work properly!

To attach temperature sensor to the heatsink you can use screw М3, and thin layer of the  thermal compound. Alternatively double-sided thermal-conductive adhesive tapemight be used and screw is not required.

PWM pinout:

5 Channel 6 output
6 Channel 5 output
7 Channel 4 output
8 Channel 3 output
9 Channel 2 output
10 Channel 1 output

For use please follow the instructions of the controller.
