Communication power supply special use sine wave inversion power supply (DC/AC)
　　 This series of sine wave inversion power supply is specially intended for communication system, power supply series and industrial automation. The product has the protection functions of DC input voltage wrong connection protection, DC input over/ under voltage protection, output overload protection, short circuit protection, DC input and segregation of DC input and AC output. It can provides RS232 digital port and can monitor work status of the inversion power supply through computer, and display the work status of the inversion power supply through LCD and LED. The product is widely used in communication equipment where non-stop power supply is required.
