2. DESCRIPTION
2.1 General
Multi Compact -functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It
is a powerful true sine wave inverter, a sophisticated battery charger that features
adaptive charge technology and a high-speed AC transfer switch in a single
compact enclosure. Beside these primary functions, however, the MultiPlus
Compact has several advanced features that provide a range of new applications
as outlined below.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the
inverter within the Multi Compact is automatically activated and takes over supply
to the connected loads. This happens so fast (less than 20 milliseconds) that
computers and other electronic equipment will continue to operate without
disruption.
PowerControl – Dealing with limited generator or shore side power
With a Phoenix Multi Control Panel a maximum generator or shore current can be
set. The Multi Compact will then take account of other AC loads and use whatever
is extra for charging, thus preventing the generator or shore supply from being
overloaded.
PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the
MultiPlus Compact to supplement the capacity of the alternative source. Where
peak power is so often required only for a limited period, it is possible to reduce the
size of generator needed or conversely enable more to be achieved from the
typically limited
shore connection. When the load reduces, the spare power is used to recharge the
battery.
2.2 Battery charger
Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted
for various types of batteries. The adaptive function automatically adapts the
charging process to battery use.
The right amount of charge: variable absorption time
In the event of slight battery discharge, absorption is kept short to prevent
overcharging and excessive gas formation. After deep discharging, the absorption
time is automatically extended in order to fully charge the battery.
