HXD-LP0818 is a high-power, industrial-grade DC-DC constant current driver board engineered perfectly for 26" to 43" inches LED-backlight LCD display modules
35~70 (VDC)
HXD-LP0818 is a high-performance LED constant current driver board specially designed for LCD display module backlight systems. It converts 12V or 24V DC input into a stable 35V-70V LED driving voltage, providing reliable power for LCD monitors, industrial displays, digital signage systems, medical equipment, and other LCD-based devices ranging from 26 to 43 inches. With high efficiency, wide dimming capability, and built-in protection functions, it ensures stable backlight operation while extending LED lifetime and reducing maintenance costs.
♦ Dual 12V/24V Input Architecture: The most exceptional feature of this backlight driver board is the simultaneous integration of 12V and 24V input.
♦ 600mA Powerful Output: HXD-LP0818 delivers a massive 600mA maximum total current and an output power capability of up to 50W, illuminating any LED backlight matrix from 26-inch up to 43-inch.
♦ Equipped with Independent Light Sensor Sub-Board: We include an independent photosensitive sensor PCB along with a 2PIN 1.25 interface cable.
♦ Industrial-Grade Thermal Design & 93.5% High Efficiency: With an outstanding 93.5% DC-to-DC conversion efficiency, energy loss is minimized. Tested stringently via full-load burn-in at 60℃±5℃, this backlight driver board ensures continuous 7×24 operation.
♦ Hardware-Level True DC Dimming: Utilizes a smooth 0V to 5V analog voltage curve 0V=Max Brightness, 5V=Min Brightness to provide flicker-free illumination, satisfying medical anti-fatigue display standards and eliminating high-frequency EMI.
♦ Adaptable Feedback Resistor Matrix: The output current can be customized from 35mA to 600mA. Our factory can adjust the surface-mounted feedback resistors to fit the unique voltage/current behaviors of your selected panel.
♦ Built-In Overcurrent Fuse Defense: An input line fuse protector prevents abrupt voltage surges or upstream power supply faults from causing catastrophic damage to your expensive LED light strips.
♦ Premium Static-Free Delivery: 100% packaged and delivered in ESD shielding bags, guaranteeing total protection against electrostatic or magnetic anomalies prior to assembly.
Channel 1: DC 12V (11.5V-13V)
