Dear teacher: I would like to know the use of emergency power supply, so I would like to ask you all about what EPS and UPS power mean What are their respective areas of use? Thank you very much！
Their common place is that there are bypass, inverter, battery charging circuit, which can provide battery inverter emergency power supply when the city electricity is abnormal. The difference is that UPS is very precise, rectifier and inverter double shift work, ensure the output interruption time is less than 10 milliseconds when power (typically 0 milliseconds interrupted, because the inverter has been at work); EPS precision is low, the outage time off time is generally greater than 10 milliseconds, between 10-50ms, if the server, this time breaks more than 20ms will restart.
UPS, uninterruptible power supply, mainly used in IDC computer room, server array, precision control system, power supply, high precision, high price, normal inverter power supply, power supply inverter power supply when the power failure.
EPS, emergency power supply, mainly used in fire, emergency lights and other occasions, low precision, cheaper than the same power UPS, normal city electricity bypass work, power supply inverter work when the power failure.
