EPS Emergency Power Supply Quotation, EPS Emergency Power Supply Manufacturer, EPS Emergency Power Supply Supplier [Shenzhen Nuonai Power] The EPS Emergency Power Supply System mainly includes rectifier chargers, battery packs, inverters, transfer switches, and system controllers. The inverter is the core, typically using DSP or single-chip CPU for SPWM modulation control of the inverter section to achieve a good AC waveform output; the rectifier charger's function is to charge the battery pack in a timely manner when the city power input is normal; the inverter's function is to convert the stored DC power from the battery pack into AC power output when the city power is abnormal, providing stable and continuous power supply to the load equipment; the transfer switch ensures smooth switching between city power 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.
