UPS is a device that supplies energy to load in case of a power failure, like an inverter. A low capacity UPS with a capacity upto 1.
UPS are primarily of 3 variants basis their working:. Hence, there is no switching and, therefore, no time delay in switching between its sources. There is no disruption in the case of a power failure, even for a nanosecond. In case of a power failure, the UPS stops charging the battery but keeps driving a load from the inverter battery. Therefore, Online UPS has a zero time delay when switching its power source. Since there are two separate supplies, the output supply must be switched between the two sources.
The switching time of an offline UPS varies from 6 ms to 10 ms, sufficient to run computers and other sensitive appliances at home but not suited for banks or hospitals, as explained earlier.
During mains OFF condition, the battery stops charging, and the relay or static switch transfers the output line to the inverter side very quickly. Simultaneously, the inverter starts drawing current from the battery, which is then supplied to the AC load. For line-interactive UPS, the inverter is part of the output. While the AC input is usual, the inverter will work in reverse to charge the battery and turn to battery power when the input fails.
The switching time is lower than Offline UPS and is generally around 5 ms. Internal components provide filtering and voltage regulation. A wide variety of input voltage variations is provided by line-interactive UPS systems before switching to battery backup. In areas where outages are uncommon, this technology is especially successful, but power fluctuations are normal. As the power cut here is only during the day time i will be using only 1 fan.
