This configuration comprises of two units of UPS's (named UPS1 & UPS2). When UPS1 is delivering power to the load, UPS2 remains idle. In case of failure in the inverter of UPS1, static switch is enabled thereby providing uninterrupted power to the load through UPS2. UPS1 runs in synchronism with UPS2, ensuring no break transfer from UPS1 to UPS2. Under healthy conditions, the batteries get charged through their corresponding rectifiers.

UPS1 & UPS2 deliver power to the critical & non-critical loads respectively under healthy conditions. UPS1 synchronizes with UPS2 & UPS2 synchronizes with the bypass. In case of a critical inverter failure, critical load works on UPS2 through enabled STSW1, simultaneously transferring the non-critical load to Bypass by activating STSW3 & inhibiting STSW2. The restoration of the critical inverter will be responsible for retransferring the loads of their corresponding inverters. The batteries are charged through their corresponding rectifiers.

Online UPS provides better overall power protection to your computers and peripherals. This protection includes power conditioning, regulated voltage and frequency and zero transfer time to battery during mains failure.

Every UPS needs to be serviced every 6 months to ensure its proper operation and battery condition.

A pure sine waveform has a peak value, which is 1.414 times the RMS value indicated on a voltmeter. A resistance or any linear load connected to such a voltage source draws currents having similar waveforms and hence has a crest factor of 1.4. As against this, the non-linear loads as described above may demand currents whose peak value to RMS ratios are 2 to 5 or more. This ratio of peak to RMS is termed as the crest factor, and is indicative of the degree of non-linear load handling capability of the UPS.

A regulated voltage source such as inverter section of ON-LINE UPS is expected to maintain the voltage at a predefined level, irrespective of changes in supply, 1.e. DC input voltage or load current levels. The percentage deviation of the output, as a result of load or dc input change,after the output voltage has settled to a new level is defined as the static or steady state regulation.

The percentage deviation of the output from its steady state value immediately following a disturbance such as sudden change of DC supply voltage or load current is termed as dynamic/transient regulation. This deviation is generally much larger than the steady state value specified as voltage regulation, and incidentally is a measure of the speed of response of inverter control system. Since by defination this is a transient quantity, not only the deviation but the time to bring the voltage back to the steady state regulation level is also an important index of performance. JET ELECTRO's Online UPS have the Dynamic Regulation on Output voltage.
