   The ratio of the output power from the UPS to the input power from

   the AC utility in Line mode.

   The duration that UPS supplies backup power to the electrical appliances while

   power failure.The unit of backup time is minute andcalculates backup time from

   black out happening to battery used up.

   The current to charging the battery that is regulated from the AC

   utility by the circuit inside the UPS.

   Complete loss of power. Some literature considers a voltage drop below about 80V

   to be a blackout as well since most equipment will not operate below these levels.

   A function to adjust the output of UPS. When the voltage is under normal condition

   then the UPS will boost the voltage higher. When the voltage is over normal

   condition then the UPS will buck the voltage lower.

   The UPS can be started from battery directly without AC utility.

   Some people also name it as DC start.

   UPSs can often communicate with computer equipment in order to allow the UPS

   to trigger a controlled automatic shutdown of the computer.This is usually done

   when the mains has failed and the UPS battery power is close to being used up.

    • EMI

   Unwanted noise during the operation of a power supply or other

   electrical or electronic equipment.

   It is the fast charging battery system to speed up charging time. For this case,

   the designer be expert and use high technology in controlling charging

   system so battery does not damage.

   Distortion of an electrical sine wave caused by the power supplies of certain

   electronic devices. A mathematical representation of a distortion of a

   pure sine waveform.

   The intelligent battery management will manage charging and discharging to

   get longer backup times and prolong battery life.

   Two circuits that are completely electrically separated with respect to DC potentials,

   and almost always also AC potentials. In power supplies, it is defined as the

   electrical separation of the input and output via the transformer.

   The maximum AC or DC voltage which maybe continuously applied from

   input to output and/or chassis of a power supply.

   A term relating to current flowing between the AC supply wires and earth ground.

   The term does not necessarily denote a fault condition. In power supplies,

   leakage current usually refers to the 60 Hertz current which flows through the EMI

   filter capacitors which are connected between the AC lines and

   ground (Y caps).

   A type of uninterruptible power supply that is in standby mode most of the time

   but contains a transformer that helps condition and adjust the voltage until the

   voltage exceeds a set limit. If the voltage limit is exceeded, the UPS can support

   the load until the voltage returns to   within the limits or the battery is drained.

   A manually operated transfer switch used to bypass the major electronics in

   the UPS. When it is enabled then the service engineer can have the repair

   service without power interruption.

   Metal Oxide Varistors are added to circuits in order to control spikes. These are

   common in Power Strips. If you see more than two, you likely have a fairly decent

   Power Strip. They look like largish disk capacitors.

   UPS will shutdown itself when the utility fails and there is no load connected to UPS.

   This feature is to prolong battery life.

   A type of uninterruptible power supply that is constantly converting the incoming

   power from AC to DC and then inverting DC back to AC. This double conversion

   process prevents power disturbances from reaching protected loads.

   The UPS batteries will support the load if conditions exceed a set limit.

   A circuit which either shuts down the power supply or crowbars the output

   in the event of an overvoltage condition.

   The ratio of true power to apparent power in an AC circuit. In power conversion

   technology, power factor is used in conjunction with describing the AC input

   current to the power supply.

   • Pulse-width modulation

     (PWM)

   A circuit used in switching regulated power supplies where the switching frequency

   is held constant and the width of the power pulse is varied, controlling both line

   and load changes with minimal dissipation.

   • Radio Frequency Interference

     (RFI)

   It is undesirable noise produced by a power supply or other electrical or

   electronic device during its operation. In power supply technology,

   RFI is usually taken to mean the same thing as EMI.

   An tremendous increase in voltage over a very short period of time often

   caused by a direct lightning strike on a power line or when power returns

   after a blackout.

   A type of uninterruptible power supply that remains in standby mode offering little

   or no power conditioning unless the voltage exceeds a set limit. If the voltage limit

   is exceeded, the UPS can support the load until the voltage returns to within the

   limits or the battery is drained.

   An substantial increase in voltage lasting a small fraction of a second, often

   caused when high powered appliances such as air conditioners are switched off.

   Circuitry consisting of MOVs, capacitors, rod-core inductors etc. for suppressing

   surges and spikes usually embedded in a power strip.

   The amount of time it takes a stand-by or off-line type UPS to sense a power

   interruption and switch from utility output to inverter output.

   Normally expressed in milliseconds.

   • Uninterruptible Power Supply

     (UPS)

   A device which maintains a continuous supply of electric power to connected

   equipment by supplying power from a separate source when utility powe

   r is not available.

   User replaceable batteries allow the user to easily exchange UPS batteries.

   Normally, the battery lifetime is close to 2~3 years.

   Transient (short term) over-voltage i.e. spike or peak: Causes wear or acute

   damage to electronic equipment.
