Parts of the UPS Uninterruptible Power Supply
Uninterruptible Power Supply UPS is basically composed of three main components, namely: 1) Rectifier-Charger This section is used to transfer circuit and battery charging. Rectifier-charger circuit block is going to supply the power needed by the inverter under full load and at that time to maintain the charge in the battery. Besides these blocks must have the ability to drain the power output of 125-130%. Characteristics of the batteries also need to be taken into account in its charger circuit design because if a rechargeable battery with a current that exceeds the capacity limit will be able to shorten the life of the battery. U sually for a battery charging current to the UPS is 80% of current conditions issued by the batteries at full load. Limitation of a UPS system is good by the standards of NEMA - National Electical Manufacturer Association - is able to provide 100% power continuously (continuous load) and 2 hours at 125% load without a decrease in performance (damage).
