Charger : in numerous UPS systems due to the nature of these design a separate battery charger is employed, this is very common on small sub 3kVA devices and is more common on sub 60kVA UPS systems.
Battery : this is actually the energy storage section and is kept charged possibly by the rectifier or a separate charger. As AH (ampere hour), which will be the amount of amperes of current that the battery can supply for an hour, Its storage capacity is normally displayed. There will be a number of limiting facets depending upon the application, typically if the design calls for a small autonomy (period of time the battery will support its weight for), the batteries may be released to a degree, in the case of emergency lighting where there is a need for a autonomy the battery will not be permitted to release so far. These circumstances help to enable the optimum design life of the battery to be achieved.
Inverter : an ac output is provided by this section of the Uninterruptible power supply to the weight which is in phase with the insight mains supply. Due to the quantity of conversions (ac to dc to ac) and the filter involved it could be termed as a 'clean supply.'
Fixed Switch : this world is often as simple as a relay or even more generally using thyristors, its function would be to move the load between the inverter and the application mains supply. To ensure that any switching between your two will soon be nearly seamless as has been earlier mentioned the result of the inverter is in phase with the power mains supply.

The load is allowed by this arrangement to be moved under controlled conditions to the UPS and the power mains to be turn off without loss. Generally performed for program UPS preservation or UPS restore.
External Maintenance Bypass : the installing an maintenance bypass can allow the UPS to be removed/replaced without interruption to the load, also, if the true maintenance bypass is given from another supply it can allow load screening in the case of an important UPS repair and/or checking of the independence under simulated load situations while the site load will be recognized by the external maintenance bypass circuit.
