Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Series and parallel with the wide voltage power supply board LED lights to be more wide? For LED solar street in a relatively wide range of input voltage range AC 85-265 V solar street lamp, the lamp LED series and parallel plates is very important. Try not to use a wide voltage, can be divided into AC 220 V solar street lights, AC 110 V as classification, so as to ensure the reliability of the power supply. Due to the current supply is generally a non-isolated step-down constant current power supply Jiangxi lights solar, requiring 110V voltage, the output voltage should not exceed 70 V solar street wholesale Nanchang, serial number no more than 23 strings. Output voltage input voltage of 220 V can reach 156V. That is, not more than 45 number of series strings. Parallel number not too much, otherwise the operating current is too large, the power severe fever. Optoelectronics Technology Co., Ltd.
