CA-155 LED Constant Current Board, 10-30V to 9.6V High Voltage Converter LED Backlight Driver with Dimming for 15-27" LCD Monitor TV

CA-155 Universal LED Backlight Driver Board 10-30V to 9.6V Constant Current Converter with Dimming

This CA-155 LED constant current board is a professional replacement for traditional CCFL inverters in 1527 inch LCD monitors and TVs, compatible with major brands including Samsung, LG, Philips, AOC, and Dell. It converts a wide input voltage of DC 10-30V (12V/24V compatible) to a stable 9.6V constant current output, supporting 12 LED backlight strips with up to 99 LEDs total.

Equipped with a dimming control pin and on/off switch pin (3.35V logic level), the board allows precise brightness adjustment and power management for the LED backlight. The non-isolated step-down circuit with a shielded inductor ensures efficient power conversion, while built-in over-voltage, over-current, and short-circuit protection safeguards the LED strips and the board itself.

Measuring 70 x 20mm, this compact driver board is easy to install with its standard 6-pin connector, requiring no complex modifications or soldering for most LCD models. Perfect for repairing faulty, flickering, or dim LED backlights, the CA-155 restores optimal brightness and reliability to your LCD display.
