Rangkaian UPS sedehana

Uninterruptible power supply (UPS), also known as a battery back-up, provides emergency power and, depending on the topology, line regulation as well to connected equipment by supplying power from a separate source when utility power is not available. It differs from an auxiliary or emergency power system or standby generator, which does not provide instant protection from a momentary power interruption. A UPS, however, can be used to provide uninterrupted power to equipment, typically for 5–15 minutes until an auxiliary power supply can be turned on, utility power restored, or equipment safely shut down.

While not limited to safeguarding any particular type of equipment, a UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss.

picture below is a simple series of UPS. This series UPS has a power of 60W (if the transformer is used more, the power output of the UPS is also greater).

When normal PLN Electricity, of the adapter (the series of the most left) will produce voltage 12 - 13 volt / 5 ampaere. This voltage is used to fill mengoprasikan UPS batery and therefore this UPS if you plan to load a higher modifikasilah of this series that have a higher ampere. PLN electricity when dead, the source voltage in the switch to akan bateray

When electricity PLN suppressed, the source voltage will switch to the battery. ups that may be living longer while the power off, use battery who have ampere / hour high (large) or can also install some of the ways in parallel battery
