EPS emergency power supply on the broad sense refers to the normal power supply is interrupted, you can load a user to key independent short supply emergency power 220v power inverter unit (EPS: Emergency Power Supply), including of course the title of this generalized emergency diesel generators. With static power inverter in building fire emergency should be as gradual application of power, the current domestic supply and fire protection industry has been referred to as the EPS is designed primarily refers to the use of power electronics inverter stationary emergency power system (hereinafter referred to as the unified EPS).
EPS emergency power supply system includes rectifier chargers, batteries, inverters, each switch device and a part of the system controller. Which is the core of the inverter, usually single CPU or DSP part of the inverter SPWM modulation control, and thus obtain a good AC waveform output; role rectified mains charger when the input is normal for the battery pack to achieve timely Charge; role inverter is abnormal when the mains, the battery pack is stored DC power into AC output, stable and sustainable supply of electricity load equipment; each switch device to ensure that 3000w charge inverter the load on mains power and inverter output between smooth handover; system controller for real-time control of the entire system, and can be a fault alarm signal and the received signal remote control linkage, and through standard communication interface from the host computer system for remote monitoring EPS.
