Details

Meanwell LDD-H is DC-DC Constant Current Step-Down LED driver designed in compact size. The entire series could operate from 9~ 56VDC and offer models with different rated current ranging between 300mA and 1500mA. The efficiency reaches high to 97%, and work at -40℃~+70℃ under natural air cooling and heat dissipation conditions. Under Built-in EMI filter and PWM and remote ON/OFF control, LDD-H complies with BS EN/EN55015 and FCC part15 without extra input filter and capacitors. Additionally, the series is equipped with various protections such as Short circuit and Over temperature. 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 long lifetime, high reliability and low cost, Meanwell LDD-H Series serves as an ideally suitable solution for driving illumination LED.
