Universal 14-37 Inch LED LCD TV Backlight Driver Board Constant Current Board

Product Description

Limit parameters
At 24V input: Vout=75Vlout=720mA or maximum 60W
At 12V input: Vout=75Vlout=400mA or maximum 30W
Limit parameters refer to the maximum endurance capacity of the product during application. In actual use, please use it below the limit parameters to ensure the reliability of the product.

Common electronic symbol codes for backlight panels in Chinese and English are as follows:
VCC: positive pole of power supply voltage, circuit supply voltage (voltage is usually 12V or 24V) ON/OFF, ON, EN, ON BL, etc.: switch pin, switch signal pin (voltage range is usually between 2.5V-5V)
PWM, PDIM, VDAJ, BL-PWM, etc.: brightness adjustment foot or dimming foot. (There are two dimming modes, one is digital mode-PWM (the voltage of the signal is usually 3.3V), and the other is analog dimming-DC (the voltage of the signal is 0-3.3V10-5V)
PWM is called pulse width modulation. It generates a rectangular square wave signal, the frequency is generally 200HZ-2KHZ, and the voltage amplitude is usually 3.3V. PDIM is the abbreviation of English, and Dim is the word for darkness, which roughly means "brightness". Analog dimming is performed through DC voltage, usually directly providing a DC voltage of 0V-5V to the adjustment pin to control the brightness. )
GND: Ground (negative pole of power supply)
LED+: light-emitting diode (light strip) positive electrode
LED-: Light-emitting diode (light strip) cathode. 

The symbols above include the codes commonly used on most LCD motherboards and backlight boards. When connecting, you only need to connect them according to the corresponding codes, and you will not go wrong.
