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-3200-350 is an intelligent dimmer dedicated to adjust the brightness of LED
light, adopted the most advanced PWM (Pulse-Width Modulation) digital
brightness-adjusting technology at present, users can either turn around the knob
manually or use the IR wireless remote control panel to control the brightness infinitely;
Suitable for installation of commercial and household 86-style socket; can install the
socket visibly outside the wall or inside the wall invisibly; it is suitable for dimming
hi-power 1W LED lamps and it’s energy-saving.

. CⅣonnection Diagram
1. LT-3200-350 connects 1W hi-power LED directly;
Friendly reminding：
1) Power Supply Selection：
Please select constant voltage switching DC power supply；
2) Power Calculation：
The effective power of the power supply in market is 80%，so users should select
a bigger Watt than the actual load of LED light, at least 20% more;
Total Power =350mA(700mA)*the total voltage of LED in series；
3) Voltage selection of Power Supply：
Voltage range: DC12-48V, the selected voltage should be higher than that of the
total LED, e.g.: the voltage of an LED is 3.6V, 3 pieces LED is 3.6*3=10.8, then
12V power supply is OK, if 6 pieces LED, then 24V is OK, but if you choose 36V is
also OK, the circuit in the dimmer ensures exact voltage & current to the LED, no
influence on LED itself.
