New 1,200/1,500 mA DC-DC CC LED Drivers from Mean Well

Mean Well has released LDD-L (300-1500 mA, step down mode and low voltage input), LDD-H (300-1000 mA, step down mode and high voltage input) and LDB-L (300-600 mA, 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 1200/1500 mA and is pleased to unveil LDD-1200-1500H/HW models.

•    Constant current step-down mode
•    Wide input (9~52 VDC) and output (2~46 VDC) range
•    High working efficiency up to 96%
•    Wide working temperature range:-40~+85°C
•    Comply with EMI without any additional components (EN55015 and FCC part 15)
•    Protections:Short circuit / Over temperature
•    94V-0 flame retardant plastic case
•    Built-in PWM dimming and remote ON/OFF control functions
•    FCC/CE approved
•    Dimension (L x W x H):31.8 x 20.3 x 12.2 mm
•    3 years warranty

These two series are both constant current step-down mode power module with 9-52 VDC high voltage input and 2-46 VDC 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.
