GENERAL
Multifunctional
The Multi 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 ana high-speed
AC transfer switch in a single enclosure. Beside these primary functions, however, the Multi 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 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.
Parallel and 3-phase operation capability (800VA and 1200VA models only)
Up to 6 inverters can operate in parallel to achieve higher power output.
Operation in 3-phase configuration is also possible.
PowerControl
– Dealing with limited generator or shore side power
With a Multi Control Panel a maximum generator or shore current can be set. The Multi 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 (800VA and
1200VA models only)
This feature takes the principle of Power Control 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.
Programmable relay
The Multi is equipped with a programmable relay that by default is set as an alarm relay. The relay
can be programmed for all kinds of other applications however, for example as a starter relay for a
generator.
