inverter -
inverter is a device which
converts dc into ac.The inverter may also contain a battery
unit and an dc to to ac
conversion unit based on application. when the power fails
the inveter will deliver power by switching from main
source to battery source. The switching time here is
normally greater than 20 ms (because of electrosattic
switching).
UPS
UPS is a device,with a combination of rectifier and
inverter which delivers power, even if the power source
fails without any interruption to load (Uninterrupted power
supply). When compared to inverter here the switching time
from main source to backup source is less than 10ms (due to
semiconductor switching), so that sensitive electronic
devices such as computers, PLC, DCS, I/O modules will not
be effected even if power fails.
