2. Description
The Enerdrive ePRO Combi is an all-in-one combination of a DC to AC true
sinewave inverter, an advanced multi-stage battery charger and a high
speed AC transfer switch. All this is built into one compact, yet installer
friendly enclosure. Besides these three main functions, there are several
unique features o
ff
ered as well. Some of which bene
fi
t from the strong
interaction between the three main functions.
The main task of the ePRO Combi is to act as an uninterruptible AC power
supply (UPS). In case of a grid/generator failure or disconnection, the ePRO
Combi immediately stops charging the battery, releases the AC transfer
switch and activates the inverter which takes over the supply to the
connected loads. All this is achieved so fast, that even very critical loads like
computers will continue to operate without any problems. In case the grid/
generator is reconnected again and the voltage and frequency are within
acceptable limits, the ePRO Combi activates the AC transfer switch and
battery charger again, while deactivating the inverter. The connected loads
are now supplied again by the grid/generator without any interruption.
Additionally, the ePRO Combi o
ff
ers features like :
• AC Input Power Boost
, which temporarily assists weak AC input
sources when the connected load needs more power than available
from the grid or generator.
• AC Input Current Limit,
which limits the maximum current consumed
from the AC input source by the ePRO Combi. This limit is user adjustable.
• Power Factor Corrected AC Input,
which optimizes energy
e
ffi
ciency and makes sure that the maximum amount of charging
current is available from your AC source.
• Intelligent 4-stage charge programs,
user programmable to
fi
t
any battery type.
