Product characteristics
　　This series of DC/DC converters is a high quality secondary power supply specially designed for communication system, power supply system, microwave center (station), etc. It adopts PWM working mode. The complete machine is characterized with high efficiency of conversion, strong capability against interference, wide range of input/out voltage, low noise level, high stability, separation of input and output, and has the protection function of automatic voltage stabilization, automatic current rectifying, over/ under voltage protection, output over current protection, over temperature protection, etc.
　　The machine can be combined with others in use, and can be widely used in microwave station, wave carrier room, digital communication, DC panel and other power supply communication equipment, and may also serve as the facility for discharge and charge of batteries. Our company also introduced integrated conversion power supply of AC200V and DC220V.
