What is the difference between EPS and UPS?
UPS is the abbreviation of UninterruptiblePowerSupply, that is, we often say UPS uninterruptible power supply. Common UPS on the market are mainly on-line (OnLine) and back-off (OffLine) two.
EPS emergency power supply system is the abbreviation of Emergency Power Supply, is to meet the special requirements of the fire industry emergency power supply.
First, the backup UPS in the normal electricity directly from the mains power supply to the load, when the electricity beyond its scope of work or power outages, through the switch to battery inverter power supply. Its characteristics are: simple structure, small size, low cost, but the input voltage range is narrow, the output voltage stability accuracy is poor, there is switching time, and the output waveform is generally square wave
Second, the online interactive UPS in the normal electricity directly from the mains power supply to the load, when the electricity is low or high, through the UPS internal regulator line regulator output, when the electricity is abnormal or power failure, through the conversion Switch to battery inverter power supply. Its characteristics are: a wide input voltage range, low noise, small size and other characteristics, but there are also switching time.
