UPS Systems

Our UPS Systems are electrical systems that provide battery backup when the electrical power fails or drops to an unacceptable voltage level. Small uninterruptible power supply systems provide power for a few minutes; enough to power down the computer in an orderly manner, while larger systems have enough battery for several hours. In mission critical datacenters, uninterruptible power supply systems are used for just a few minutes until electrical generators take over. The run-time for a UPS depends on the type and size of batteries and rate of discharge, and the efficiency of the inverter. The total capacity of a lead-acid battery is a function of the rate at which it is discharged. Manufacturers supply run-time rating in minutes for packaged UPS systems. Larger systems (such as for data centers) require detailed calculation of the load, inverter efficiency, and battery characteristics to ensure the required endurance is attained. PLC Technologies South Africa supplies a wide range of UPS Systems from 1KVA to 13MVA.
