Charger : in several UPS systems due to the character of the design a separate battery charger is applied, this is more common on sub 60kVA UPS systems and is extremely common on small sub 3kVA units.

Rectifier : this element of the UPS converts the incoming alternating current (ac) supply to direct current (dc) and can offer charging current for the battery and also the supply requirements for the inverter.

Charger : in a number of UPS systems as a result of nature of the design a separate battery charger is applied, this is more common on sub 60kVA UPS systems and is quite common on small sub 3kVA items.

Battery : this is actually the power storage section and is kept charged both by the rectifier or even 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 generally exhibited. There will be a number of limiting factors dependant on the application, usually if the design calls for a small autonomy (length of time the battery will support its load for), the batteries can be cleared to a degree, in the case of emergency lighting where there's a necessity for a autonomy the battery won't be permitted to release therefore far. These conditions help 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 load which is in phase with the input mains supply. Because of the quantity of conversions (ac to dc to ac) and the filter involved it may be termed as a 'clean supply.'

Fixed Switch : this signal can be as easy as a relay or more generally using thyristors, its goal would be to move the load between the inverter and the power mains supply. As has been previously mentioned the production of the inverter is in phase with the utility mains offer to ensure that any switching involving the two will be nearly seamless. This arrangement ensures that if the inverter experiences an overload situation, due to its very quickly over-current detection tracks it'll transfer force to the more sturdy mains supply. A normal example would be each time a host tray is switched on, the inrush current, depending upon the size of your uninterruptible power supplies, may cause the transfer to the power mains supply, and once switched on the load may transfer back to the inverter offering the inverter has sufficient ability to support the load. Also a mistake on the inverter may cause the load to be transferred, again nearly seamlessly; it would be unusual for just about any loss of load that occurs over these circumstances.

Maintenance Bypass : more typically within UPS systems with a volume of 6kVA or greater. The load is allowed by this arrangement to be moved under controlled conditions to the utility mains and the UPS to be power down without damage. Normally performed for program UPS preservation or UPS fix.

External Maintenance Bypass : the installation of an maintenance bypass can allow the UPS to be removed/replaced without disturbance to the load, also, if the true maintenance bypass is given from a different supply it can allow load testing in the case of an important UPS restoration and/or checking of the independence under simulated load problems while the site load has been recognized by the external maintenance bypass circuit. When letting the UPS System to be bypassed onto standby diesel generator power this could be used. Alternatively, when batteries are replaced and removed, it could only be achieved by setting the uniterruptible power supply into additional bypass.
