HXD-LP0632-3C Key Features

♦ Wide Dimming Range: Supports 0V to 5V analog dimming voltage control ( $0\text{V} = \text{Maximum brightness}$ , $5\text{V} = \text{Minimum brightness}$ ) for precise brightness engineering.

♦ Ambient Light Sensor Interface: Built with a dedicated CN2 (4P 1.25) external light sensor interface, enabling your device to automatically dim or brighten based on ambient light. Perfect for outdoor readable displays.

♦ Comprehensive Circuit Protection: Integrated fuse protection on the input line safeguards your critical mainboards against input overcurrent overloads.

♦ ESD Shielded Packaging: Shipped 100% in ESD shielding bags to protect sensitive components from electrostatic or magnetic interference during transit.

♦ High Performance, Low Power Consumption: Featuring an impressive efficiency of up to 93.5%, it significantly minimizes heat accumulation inside industrial enclosures, extending the life of both your LED light strips and LCD panels.

♦ 100% Flexible Adjustment to Match Your Screen: The output current can be finely tuned between 35mA and 350mA by adapting the feedback resistors based on your backlight datasheets. One LED driver board fits multiple TFT LCD panel models, reducing your inventory pressure.

♦ Proven Industrial Reliability: Every batch passes rigorous full-load burn-in testing at $60^\circ\text{C} \pm 5^\circ\text{C}$ and low-temperature startup tests, guaranteeing reliable 24/7 operation in harsh environments from $-20^\circ\text{C}$ to $70^\circ\text{C}$ .

HXD-LP0632-3C Installation & Assembly Notices

• Safety Clearance: To prevent high-voltage breakdown, ensure a minimum clearance of at least 5.0mm between the inverter board and any metal parts of the system, or add an approved insulation sheet.

• Unused Channels: If any group of output lines is not required for your screen layout, please leave that terminal floating (unconnected).

• ESD Handling: Since this product is an open-frame inverter without an outer enclosure, always use proper ESD grounding wrist straps during unboxing, testing, and installation.
