A. UPS is the abbreviation for Uninterruptible Power Supply. In very simply terms it is a Power Conditioner with a battery. By adding the battery it is possible to offer protection against power failure / black outs. Generally there are two types of systems available in the market today – Online and Offline / Standby. Basically a UPS will consist of three key elements:- Rectifier / Charger – takes the incoming AC supply and converts it to DC to trickle charge the DC battery and where applicable feed the inverter. Inverter – takes the DC from the battery and where applicable the rectifier converting it to a regulated AC voltage to feed the critical load. Battery – a collection of cells used to store the DC voltage.
