The SSG SERIES represents the
smallest and most compact units of the
Falcon (UPS) product line. In the
tradition of all Falcon products, it
maintains the highest reliability and the
most complete on-line, sinewave power
protection available. An on-line,
sinewave UPS is the only total solution
to virtually any power problem. It
effectively provides just what it says,
Uninterruptible Power. There is no
break, transient or glitch in source
transfer on a power outage because
THERE IS NO TRANSFER.
The SSG is engineered with the latest
MOSFET/PWM technology for high
efficiency and reliability.
Refer to the simplified block diagram,
Figure 1, for system description. The AC
source is rectified and provides energy
for the DC - DC Converter and a float
charge to a standby Battery. The DC
Converter then supplies the power to
operate the PWM DC/AC Inverter.
During a utility power-loss, the AC
rectification and battery charging
capabilities of the UPS become inactive.
The fully charged battery, however,
supplies the necessary power
requirement to maintain the remaining
system blocks.
The SSG on-line topology is unique to
other on-line systems in that it is
designed to meet the needs of non-
linear loads. Your computer, withits
switching power supply, is considered a
nonlinear load which can be very
abusive to most power protection
equipment and could decrease its life-
expectancy. The SSG is specially
devised to accept these loads and
protect them efficiently without any of
the output waveform degradation
common to other UPS.
If the unit inadvertently experiences an
extreme over temperature situation that
causes inverter malfunction, it will switch
over to a filtered emergency bypass line
to insure continuous power to the
computer load. If the unit is overloaded,
it will shutdown completely if the
overload is not corrected within 15
seconds.
The SSG500 offers complete isolation
input to output.
