Scope of application
Applicable to the railway system, power plant design, used for power telecontrol, communication, monitoring, emergency lighting, power plants can also exchange lubricating pump, AC fan, sine wave power supply reliable equipment.
[solution]
Power inverter is a new generation of dual input inverter solution designed for communication applications. It uses a new design architecture to help users to provide a clean, stable and durable AC power supply for critical loads, and has the same high reliability as the DC power supply system n+x. The design features of the inverter to ensure that it can be achieved between the AC and DC power supply seamless conversion, no conversion delay, and no need to use static conversion switch.
The user can choose the "line power supply" and "battery powered" two modes. When in the wired power supply mode, inverter working mode and double conversion is similar to the UPS, can be converted into AC power smoothing independent alternating current power supply to the load; when in the "battery" mode, the inverter directly by a DC power supply. When the power supply is interrupted by the preferred input power supply, the inverter can seamlessly switch to the standby input power without interrupting the supply to the key AC load.
