Standby Mode
UPS consists of a rectifier, a set of batteries, and an inverter. It enables
the batteries to be charged through the rectifier and, at the same time,
provides supply to the load during normal conditions. (Figure 1)
Emergency Mode
The battery will restore its energy in the form of DC currents to the
inverter, and the inverter will supply AC currents to the load when the mains
fails (Figure 2).
When the AC mains resumes, the batteries will be recharged
immediately through the electrical change over contact. The mains will
supply to the loads as shown in (Figure 1).
