Details
Meanwell LDD-700H is DC-DC Constant Current Step-Down LED driver with 700mA2-52VDC200mVp-p40KHz~1000KHz2.2uF9~56VDC47~63Hz650mA5mA. The model is designed in compact size, and could operate from 9~ 56VDC with rated current 700mA. In addition, 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-700H complies with BS EN/EN55015 and FCC part15 without extra input filter and capacitors. It is also 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. As a result of its long lifetime, high reliability and low cost, Meanwell LDD-700H is an ideally suitable solution for driving illumination LED.
