Mean Well Launches New DC-DC Constant Current LED Driver for Aquarium Illumination

Mean Well introduces new DC-DC LED driver for aquarium lighting. (Mean Well/LEDinside)

MEAN WELL has released LDD-L (300~1500mA, step down mode and low voltage input), LDD-H (300~1000mA, step down mode and high voltage input) and LDB-L (300~600mA, buck-boost mode and low voltage input) series into the DC-DC LED constant current driver market for years and has been widely adopted. In order to further meet the application demands, MEAN WELL pushes the output current of LDD-H series up to 1200mA/1500mA and is pleased to unveil LDD-1200~1500H/HW models.

These two series are both constant current step-down mode power module with 9~52VDC high voltage input and 2~46VDC output. Having both the PIN style (H-Type) and the wire style (HW-Type), the internally potted design makes them able to withstand water and dust. Both exploit non-isolated buck topology design that the highest working efficiency reaches 96%. The dimension of the whole LDD-H/HW family are all 31.8 x 20.3 x 12.2 mm; it is convenient for those lighting system designers who have already adopted products of MEAN WELL but require a higher output current to upgrade by using new drivers directly without changing the initial circuit design.

The typical applications of DC-DC LED constant current drivers is to connect them in back of the AC-DC constant voltage type LED drivers, providing a constant current to drive the LED luminaires that reach the stable constant current state and extend the life-span of the luminaires. These products are very suitable to be applied to the outdoor or indoor LED lighting systems which utilize the AC-DC LED drivers of MEAN WELL, such as: street lighting, landscape lighting, tunnel lighting, household lighting, commercial lighting, and so on.
