Pure sine wave inverter is a new generation ofdual input inverter solution designed for the field ofcommunication applications, which is suitable for thehigh reliability of the communication system. Thesolution is equipped with a 96V/110V/220V/230V ACpower supply and a 24V /48V/110V/220V DC powersupply, which fills the gap between the traditional UPSpower supply and common pure sine wave invertersolutions.

It uses a novel design structure that helps users toprovide clean, stable and durable AC power for criticalloads, and has the same high reliability as the DC powersupply system. The design characteristics of thededicated communication pure sine wave inverterensure the seamless conversion between the AC and DCpower supply, almost no conversion delay, and no needto use the static switch

Hardware structure and working principle
AC power supply mode

Namely AC inverter working mode: the inverter employs mains for load when there is mains and switches to inverter working mode when the mains is abnormal.

DC power supply mode

Namely DC-dominated inverter working mode: under normal condition, DC-dominated inverter is under inverter output status all the time; in case of DC fault, it switches to mains by-pass.
