Details
Meanwell LDD-1050H-DA is DC-DC Constant Current Step-Down LED driver with 1050mA3-45VDC±5% at 48VDC input150mVp-p500KHz1400uF6~50VDC47~63Hz825mA5mA. It is designed in compact size operating from 3~ 45VDC with rated current 1050mA. Meanwhile, the efficiency reaches high to 95% at -40℃~+85℃ under natural air cooling and heat dissipation conditions. Based on Built-in EMI filter and PWM and remote ON/OFF control, LDD-1050H-DA complies with BS EN/EN5501 5 without extra input filter and capacitors. Furthermore, the unit is provided 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. In light of its longevity, high reliability and low cost, Meanwell LDD-1050H-DA is an ideally suitable solution for driving illumination LED.
