Product characteristics
It adopts the internally popular current control mode (PWM technology) and the highly stable and reliable circuit structure. It has power factor compensation. The complete machine is characterized with wide range of voltage, average division of dynamic load, high power density, small volume, light weight, strong protection functions and high reliability. The major technical data are higher than the national standard YD/T731-1994. The protection function of the rectifier is perfect, and it can effect remote control through the intelligent monitoring port RS232. The machine is a rectifier of parallel connection, and has redundance configuration of N+1, ensuring the maximum reliability of the system. It can conduct charge and discharge for batteries (the maximum capacity of the battery 48/500AH, 24/1000AH).
