Reserve UPS power supply mode is that the city power input UPS power, divided into two running, all the way for equipment direct power supply, the other way through the UPS power supply will be converted to DC power supply for battery charging
The characteristics of online is that the inverter has been in working condition, the switching time of the power supply is zero; the output voltage and frequency stability, UPS battery used in Hercules power quality requirements of very high, because there is no switching time delay, it is reliable; the online can improve the quality of power supply, so the price is relatively expensive.
Power supply line UPS is UPS power supply input, Hercules battery is the converted DC voltage, DC current output for battery charging, battery through the inverter UPS power into AC output power to the equipment.
