LDD-H-DA series is a constant current step-down converter with 6~50VDC high input voltage and 3~45VDC output voltage. Its output current range covers 350~1400mA with DALI dimming function, which meets the needs of DALI intelligent control in lighting fixture system. LDD-H-DA is thoroughly potted, reaching IP65 waterproof and dust proof protection level. LDD-H-DA has built-in PWM and analog dimming function, remotely controlling power ON/OFF, and PWM function is able to further adjust output current. LDD-H-DA can be deployed to the DC output side of constant voltage AC/DC LED driver, providing constant current to drive LED luminaries to stabilise current and extend fixtures lifespan. This product is suitable for indoor and outdoor LED lighting systems, such as street lighting, landscape lighting, tunnel lighting, household lighting and office lighting.
