LT-3900
LED RGB Controller
ISO9001:2008
LT-3900 is a multi-functional RGB controller, built-in 32 modes, adopts advanced PWM (Pluse-
Width Modulation) control technique, smooth changing effect, without flicker. Adopting hi-power
MOS driver, RGB 3 channels output and total current up to 18A; With unique touch technique,
the controller has 8 touch buttons, which are used for choosing ON/OFF, PAUSE, MODE+/-,
SPEED+/-,BRT+/-. It can automatically adapt to DC5-24V input, suitable for most conventional
RGB LED products, such as LED strips, LED modules, etc. and all low-power RGB LED lights
whose current is limited by resistors can be controlled.
