Description
Universal 32-60 inch LED LCD TV backlight constant current booster board 55-255V output constant current board
for TCL. Konka. Skyworth. Changhong. Hisense. Haier and other brands of television triple-board backlight drive circuit repair or TV assembly. Input voltage 40-165V, output 55-255V
for TCL. Konka. Skyworth. Changhong. Hisense. Haier and other brands of television triple-board backlight drive circuit repair or TV assembly. Input voltage 40-165V, output 55-255V
If you do not know the required voltage of the backlight bar, please install from the minimum current (default 200MA) to try,backlight brightness is not enough then slowly increase, do not use the maximum current to light the backlight, it is easy to burn light or drive board.
CA-233 current adjustment instructions:
J1 = 20MA
J2 = 40MA
J3 = 60MA
J4 = J5 = 100MA
J6 = 200MA
Connecting instruction:
1.In the integral power board rectification out for the backlight of the filter capacitor positive voltage to the VCC, the voltage range between 45v-165v
2. Then 12-24V voltage to VIN, can not be connected to more than 45V high voltage
3. Connect the power ground to GND
4. NC is empty, not connected
5. In the original power board to find the switch signal received ON / OFF, the reference range of 2.5V-5V
6. The original machine's dimming signal connected to the VADJ feet, 5V is the darkest, 0V is the brightest
The default output 200MA, through the short-circuit solder joints can increase the corresponding current value (on the basis of 200mA plus), be careful not to increase the excessive current, so as not to burn the light bar.
On the input voltage: the constant current plate needs 2-way voltage input, VCC then 40-165V voltage, VIN then 12-24V voltage,only one voltage will not boost.
Tip: drive board power to pay attention to insulation, power after the power should not immediately put on the iron and the like conductive material. After power supply, pay attention to the discharge of 400V electrolysis (to avoid electric shock or damage).
Winter body static strong, do not directly touch the semiconductor board on the circuit board (you can wash hands and then touch).
