| Advanced Battery Management |
| A three-stage charging system designed to prolong
the service life of UPS batteries . By charging the batteries
only when necessary, battery life is significantly improved.
Charging stage one : quick recharging battery to approximately
to 90% . Charging stage two : fully charges the battery to 100%
.Charging stage three : rest mode prevents overcharging. Charging
stage one is initiated after a power outage or periodic UPS
self-test. |
| AC |
| Alternating Current electrical power supplied
by utility company or from an AC generator. |
| AC Metering |
| Measurement of AC power input voltage and current
parameters by sampling. The results of the measurements are
used to calculate the rms equivalents for voltage , current
and power ,and also calculate the power factor frequency. |
| AC Utility |
| The electric power furnished by an electric power
utility company. |
| Active Load Share |
| A current sharing scheme controlled by the SM50
adjusts the output voltage of individual rectifiers so that
all rectifiers in a system produce the same output current . |
| Active Voltage Control |
| The SM50 adjusts the rectifier output voltage
to maintain a constant system voltages to maintain a constant
system voltage ( measured at the output or battery) independent
of load fluctuations during normal operation. |
| Agent |
| A software program that acts as a focal point
for data collection and configuration of a specific network
entirty ( hardware or software). SNMP agents provide data to
management station regarding the operation and configuration
of devices on a network. |
| Alternate Current(AC) |
| Current which changes( or alternates ) direction
at regular intervals. Since the current flows in one direction
for the same amount of the time that it flows in the opposite
direction, the average value of the current flow is zero. |
| Ampere ( AMP or A) |
| The unit of measure for current. One ampere is
the amount of electricity per second that flows through a conductor
such as a wire. |
