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

Charger : in numerous UPS systems as a result of nature of these design another battery charger is used, this is more common on sub 60kVA UPS systems and is extremely common on small sub 3kVA devices.

Battery : here is the energy storage area and is kept charged both by the rectifier or a separate charger. Their storage capacity is usually shown, as AH (ampere hour), which will be the amount of amperes of current that the battery can provide for an hour. There will be a quantity of limiting facets depending upon the application, typically if the design calls for a short autonomy (period of time the battery will support its weight for), the batteries could be released to a level, in the case of emergency lighting where there is a requirement for a autonomy the battery won't be allowed to release so much. These problems help to enable the maximum design life of the battery to be performed.

Inverter : an ac output is provided by this section of the Uninterruptible power supply to the load which can be in phase with the input mains supply. Due to the number of conversions (ac to dc to ac) and the selection involved it could be termed as a 'clean supply.'

Static Switch : this circuit is as easy as an exchange or more commonly using thyristors, its purpose is to change the load between the inverter and the energy mains supply. To ensure that any switching between the two will soon be virtually seamless as has been mentioned before the output of the inverter is in phase with the energy mains offer. This arrangement ensures that if the inverter experiences an overload condition, because of its extremely fast over-current discovery tracks it will move the load to the more sturdy mains supply. An average example would be each time a server stand is switched on, the inrush current, depending upon the size of one's uninterruptible power supplies, may cause the transfer to the application mains offer, and after switched on the load will transfer back to the inverter giving the inverter has sufficient ability to support the load. Also a mistake on the inverter can cause the load to be transferred, again essentially seamlessly; it would be unusual for any lack of load that occurs over these circumstances.

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

External Maintenance Bypass : the installing of an maintenance bypass can allow the UPS to be removed/replaced without disturbance to the load, also, if the actual maintenance bypass is fed from a separate supply it can allow load screening in the case of a significant UPS fix and/or checking of the autonomy under simulated load situations while the site load is being recognized by the external maintenance bypass circuit. When allowing the UPS System to be bypassed onto standby diesel generator power this is used. Alternatively, when batteries are removed and replaced, it can only be done by setting the uniterruptible power supply into additional bypass. web address
