Beijing EPS Emergency Power Supply Supplier, Beijing EPS Emergency Power Supply Wholesale, Beijing EPS Emergency Power Supply Manufacturer. The EPS emergency power system mainly includes rectifier chargers, battery packs, inverters, transfer switches, and system controllers. The inverter is the core component, typically using DSP or single-chip CPU for SPWM modulation control of the inverter section, ensuring a good AC waveform output; the rectifier charger's function is to charge the battery pack in a timely manner when the main power supply is normal; the inverter's role is to convert the stored DC power from the battery pack into AC power output when the main power supply is abnormal, providing a stable and continuous power supply to the load equipment; the transfer switch ensures smooth switching between main power supply and inverter output; the system controller performs real-time control of the entire system, can issue fault alarm signals, and receive remote interlock control signals, and can be remotely monitored through standard communication interfaces by the host computer.
