>>>>>ON LINE UPS -- HAS MUCH MORE FEATURES THAN OFF LINE AND PRICE WISE ITS PRICE IS Much higher THAN OFFLINE
IN ONLINE UPS THERE IS NO CHANGE OVER TIME SO THE SENSITIVE EQUIPMENT LIKE PC DOES NOT REBOOT,OUTPUT IS PURE SINE WAVE,THERE ARE MANY PROTECTIONS FORM MAIN UTILITY IS PROVIDED BY UPS LIKE (SPIKES,RUGGEDNESS,TRANSIENTS,HARMONICS,OVER VOLTAGE,UNDER VOLTAGE,SHORT CIRCUIT)
WHICH ARE NOT MAINLY FOUND IN OFFLINE UPS.
IN ONLINE BATTERY IS ALWAYS IN OPERATION (AC-DC -BATTERY -DC -AC)
>>>>>IN OFFLINE THERE IS A CHANGE OVER OF FEW MILLI SECOND
ONLY FEW PROTECTIONS ARE PROVIDED
BATTERY IS NOT IN CONTINUOUS OPERATION (IT COMES IN PICTURE ONLY WHEN MAINS FAILS)
