①: Emergency Power Supply (EPS) system consists of a rectifier, static switch module / manual bypass switch, a control unit and inverter, racks, battery, of which the inverter is the core. The role of the rectifier is converted into alternating current, battery charging and power supply to achieve the inverter module; inverters convert direct current into alternating current role sucked, stable and sustainable supply of electricity load equipment; static switch can set the system to work In the back-up or online in two ways, and adjust the output of the inverter mains synchronization, ensure that the load between the mains and the inverter output is switched smoothly. Manual bypass switch can switch the load to mains and isolated from the system, so that when the system does not interfere with normal maintenance work load equipment. Monitor the entire system, and an alarm signal, and can be connected to the computer through a serial port or Modem, power supply system to achieve computer monitoring and remote monitoring. Widely used in various types of electricity is interrupted load level and is particularly important emergency power exchanges, such as the supply of various types of critical computer systems; working power supply all types of building and fire; the hospital security of electricity supply; transport system highways, tunnels, supply all kinds can not cut production, laboratory equipment; supply power systems; power subway, light rail, civil airports. Is a pure sine wave devices require high quality power supply.
