Because time is different forms of energy can be made of different generators. Use of water resources and turbines with, hydro can be made; the reservoir capacity and head of the deep gap between high and low DSE2157 can be made of different hydro capacity and speed. The use of coal, oil and other resources, and boilers, steam turbines with, can be made turbine generator, such as high-speed motor generator more (3000rpm). In addition to the use of wind, nuclear, geothermal, tidal and other types of energy generators. In addition, due to the different generator works and divided DC generator, asynchronous and synchronous generators. Synchronous generators are currently widely used in large generators. Hydro: the turbine-driven generators. High pressure type LED Product Controller: high pressure type LED product design voltage is AC / DC 220V voltage, LED quantity 36-48 each loop in series, each loop current of 20mA or less, limiting the way, there are two wholesale DSE2157, one is limiting resistor, the resistance power in this way, the proposed use of every four LED series with a 1 / 4W metal mold resistance, uniform distribution of heat, which is the most stable and reliable connection; the other is limited by a series resistor-capacitor flow, this connection most of the voltage drop across the capacitance, low resistance power, can only be used in a stable long bright state, if the flash capacitor discharge, but voltage doubler, LED easily damaged. Any use of the controller must use the current-limiting resistor LED mode, LED is generally one meter for each loop controller DSE2157, power 5W, three-color power per meter 15W. Common gradient controller NE112K control the DC 1200W, NE103D 4500W AC load DC load 1500W DSE2157, if the lamp flashes on the use of multi-unit NE112K, if you only need to use the whole flash NE103D. If you use a gradual way, pay attention to the load matching, neon and LED luminous distribution is not the same, the same circuit can not mix different types of loads connected. Controller DSE2157, deep sea controller (certified), DSE2157 provided by the Dongguan City, South City Zhongxin Electrical and Mechanical operation. Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) Dongguan, Guangdong, industrial products leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Zhongxin Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create a better future for electromechanical faithful.
