What are the different types of Uninterruptible Power Systems and how do they differ?
There are three distinctly different UPS systems that you can purchase. They are the Back-Up (stand-by) system, the Line Interactive system and the True Online Double Conversion System. • Backup systems provide a low level of power filtration but are installed primarily for battery backup in case of a power outage. • Line Interactive UPS’s apply automatic voltage regulation (AVR) which bucks and boosts the electrical signal so that it maintains a standard of +/- 240 volts. These UPS’s can apply this AVR to an input variance of 30 percent before sending it into battery backup. This means that it can manage dips and surges from 168 to 312 volts without the battery being employed. Once the voltage dips below or surges higher than this range, the battery will take over, promising cleaner power for your sensitive electronic systems. • The True Online Double Conversion UPS actually takes the AC current coming into the system, converts it to DC and then back to AC for the running of crucial e
