LDH-25
DC-DC Step-Up Constant Current LED driver
-
DC-DC Step-Up Converter: Designed to elevate lower DC input voltages up to higher DC output voltages specifically for driving series-connected LED strings.
Constant Current (C.C.) Output: Delivers tightly regulated, fixed-current drive configurations to prevent thermal runaway in LEDs.
Wide DC Input Operating Range:
LDH-25 / LDH-65: 9.5VDC to 32VDC input coverage (ideal for 12V or 24V solar/battery banks).
LDH-45 Series: Available in two input options: A-Type (9VDC to 18VDC) or B-Type (18VDC to 32VDC).
High Efficiency Performance: Yields electrical efficiency conversion rates reaching up to 95.5% (LDH-25), 95% (LDH-45), and 96% (LDH-65).
Flexible Mounting Configurations: Available as a direct PCB pin-mount module or pre-wired with flexible lead-wire cables.
Integrated Control & Dimming Options:
Standard Models: 2-in-1 dimming utilizing either 0–10VDC analog signals or pulse-width modulation (PWM) control, plus remote ON/OFF.
DA Models (LDH-45DA / LDH-65DA): Features integrated digital addressable lighting interface (DALI) protocol compliance alongside remote ON/OFF.
Built-in EMI Filtering: Fully complies with EN55015 electromagnetic emission standards without demanding external input capacitors or filter chokes.
Environmental Encapsulation: Fully potted with a UL 94V-0 flame-retardant silicone compound to ensure structural durability and optimize thermal heat dissipation.
Cooling Infrastructure: Operates silently via free-air convection with zero mechanical fans required.
