3.7 P̲O̲W̲E̲R̲ ̲S̲Y̲S̲T̲E̲M̲
The total ASC must function with high availability,
and the system is depending on continuous power supply.
The external power is of limited quality in terms o
voltage and frequency tolerances.
The optional no-break power system for the ASC is a
complete, modern solid state uninterruptable power
system with built-in voltage and frequency stabilization,
see figure 3.7-1 for schematic functioning.
The o-break power system is permanently coupled to
the ASC, inclusive the battery element; which eliminates
any switching in case of mains failures and results
in an un-interrupted message switching function. The
uninterruptable power system is dimensined for a freestanding
power supply from the batteries of 1/2 hour with a
12 hour recharging period.
In order to provide for the 6 hour main power failure,
a diesel generator is a part of the option. In case
of main failure of more than a short ime the generator
is switched in. The battery itself is providing the
direct short time power supply.
The generator can, however, be replaced by an existing
generator or another alternative power source, which
will reduce the price considerably.
For maintenance purpose, or in the event of a failure,
the charger and inverter can be bypassed, utilizing
a Constant Voltage Transformer (CVT) which will be
able to supply the ASC from either the generator or
the main supply.
