Details

Meanwell LDD-500H is DC-DC Constant Current Step-Down LED driver with 500mA2-52VDC150mVp-p40KHz~1000KHz2.2uF9~56VDC47~63Hz450mA5mA. It is designed in compact size from 9~ 56VDC with rated current 500mA. At the same time, the efficiency reaches high to 97%, and work at -40℃~+70℃ under natural air cooling and heat dissipation conditions. Based on Built-in EMI filter and PWM and remote ON/OFF control, LDD-500H complies with BS EN/EN55015 and FCC part15 without additional input filter and capacitors. Apart from them, the item is provided 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. In light of its long lifetime, high reliability and low cost, Meanwell LDD-500H is an ideally suitable solution for driving illumination LED.
