Details
Meanwell LDD-300L is DC-DC Constant Current Step-Down LED driver with 300mA±5% at 24VDC input150mVp-p40KHz~1000KHz2.2uF47~63Hz5mA. The product is designed in compact size, and operates from 6~ 36VDC with rated current 300mA . The work efficiency reaches high to 95%, and work at -40℃~+70℃ under natural air cooling and heat dissipation conditions. Under Built-in EMI filter, LDD-300L complies with BS EN/EN55015 and FCC part15 without additional input filter and capacitors. Additionally, the item 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. Due to its longevity, high reliability and low cost, Meanwell LDD-300L is an ideally suitable solution for driving illumination LED.
