Details
Meanwell LDD-H-DA Series is DC-DC Constant Current Step-Down LED driver with DALI designed in compact size. The entire series could operate from 3~ 45VDC and offer models with different rated current ranging between 350mA and 1400mA. The efficiency reaches high to 95%, and work at -40℃~+85℃ under natural air cooling and heat dissipation conditions. Under Built-in EMI filter and PWM and remote ON/OFF control, LDD-H-DA complies with BS EN/EN5501 5 without extra input filter and capacitors. In addition, the series is equipped with various protections such as Short circuit. LDD, LDB, LDH series are all DC-DC constant current output LED drivers, LDD is step-down type, LDH is step-up type, and LDB is buck-boost type model. The packaging forms have three forms: pin type, lead type and SMD chip type, which is convenient for various application scenarios. Considering its longevity, high reliability and low cost, Meanwell LDD-H-DA Series serves as an ideally suitable solution for driving illumination LED.
