4X Universal Boost Constant Current LED Driver Board for 1065 inch TV Backlight, Adjustable Dimming

Model CA6019 Constant Current LED Driver Board Overview This compact constant current driver board converts a 1028V DC input into a voltage constantcurrent output for LED strings. It provides selectable output up to 165V and builtin protections to support reliable LED driving in lighting, signage, and retrofit applications. Key benefits Stable constantcurrent output for consistent LED brightness and longer component life Wide input range for flexibility with common DC supplies stepup capability to drive long LED strings from lowervoltage sources Adjustable dimming and simple activation input for integration with control systems Compact, lightweight design for easy installation in tight spaces Main features and specifications Model: CA6019 Input voltage: 1028 V DC Output voltage: 5165 V DC Total output power limit: 40 W or less Default LED current: 248 mA; can be set to 600 mA by shorting the specified pads on the board Boost ratio: 1 to 7.5. Example outputs cited: 12 V increased to 80 V, 24 V increased to 160 V Control and connections: VCC, GND, IN (activation), ADJ (dimming); output uses separate positive and negative LED output terminals Dimming input range: 0 to 3 V. 0 V yields maximum brightness; about 2.0 to 2.5 V produces very low brightness; near 3 V the output is effectively off Protections: softstart and other protection features included. When the shutdown input is not used, it should be tied to ground; leaving it disconnected is not recommended Color: green Material: plastic Size: 110 x 50 mm Package contents 4 x Constant Current Driver Board (Model CA6019) Only the items listed above are included. Typical applications Driving long LED strips or multiple LED modules where a output voltage and constant current are required Backlighting and signage installations that use a lowvoltage DC supply but require higher LED string voltages Retrofit projects and custom lighting fixtures that need adjustable dimming and reliable protection features Notes and user guidance Respect the total output power limit of 40 W to avoid overloading the board Set the LED current by default to 248 mA, or change to 600 mA by shorting the board pads as indicated Tie the shutdown input to ground if it is not used to ensure proper protection behavior Color and appearance may vary slightly from product images. Allowable measurement tolerance is plus or minus 13 cm Condition units, quality inspected This driver board is intended for technical use by those familiar with LED driver wiring and power limits. Follow safe wiring and installation practices and verify compatibility with your LED modules before connecting.
