Product Details

Description:
Common backlight electronic symbol codes:
1. VCC: positive power supply voltage, circuit power supply voltage (generally 12V or 24V)
2. On / off, on, on, on BL: switch signal pin
3. PWM, PDIM, vdaj, bl-pwm: pin brightness adjustment
Ground (negative)
Led positive (lamp)
Negative pole of light emitting diode (lamp)
Application:
Product features:
·10-42 inch LED backlight driving board CC control board
·Pulse structure
·The conversion efficiency is over 92%
·The equipment has low heat dissipation, good stability and long service life
·PCB has small volume and exquisite design, and the current control error is within ± 5%
·You can use 12V power supply to reduce system cost!
·This product is a DC control board with automatic voltage regulation
·The temperature rise shall be controlled at about 25 degrees (temperature rise = equipment surface temperature - ambient temperature)
·Limit parameters:
At 24V input: Vout = 75V Vout = 720mA maximum or 60W
When the input voltage is 12V: Vout = 75V IOUT = 400mA maximum or 30W
reminder:
Limit parameter refers to the maximum capacity of the product during application. In fact, please use it under parameter limits to ensure the reliability of the product.
This product is a constant current board, which focuses on constant current and automatic voltage adjustment. The voltage is automatically adjusted according to the string of backlight modules. For example, the voltage is automatically adjusted to 3 when the backlight modules are 4 strings and 20 strings 2 V * 20 string = about 64V. Assuming that each LED current string is 60mA, you only need to set the current to 240mA to focus on this screen.
The magnetic ring wound with iron silicon aluminum material has large inductance, high temperature coefficient, large magnetic saturation and good stability. Due to the high conversion efficiency of the system, the device has very low heat, and the temperature is controlled at about 25 ℃ (Note: temperature = device surface temperature - ambient temperature), When the ambient surface temperature is between 25 ℃ and 50 ℃ (working conditions: input 24V, output 64v480ma).
 
Package Include:
2PCS 10-42 Inch Universal LED TV Constant Current Board Inverter Driver Board
