is a fully
automatic, “set and forget” charger. It's designed to quickly and
accurately recharge your batteries while maximising service life.
And what's more multistage smart charging technology enables the
charger to be connected to your battery banks permanently.
Most batteries require a multistage charge sequence for perfect,
fast and accurate charging. The
- Stage 1 Bulk or Boost Charge: The
battery is charged at full rated output current of the charger
until the battery reaches its final charging voltage, known as its
absorption voltage. In this step, around 80% of the battery
capacity is recovered as fast as possible.
- Stage 2 Absorption Charge: With the
charger voltage held steady the remaining 20% is replaced allowing
the current to drop as the battery approaches its full
charge.
- Stage 3 Float: Finally, in the float
stage the charger voltage is lowered and held at a constant and
safe predetermined level. This prevents the battery from being
overcharged while supporting any additional loads connected to the
battery, such as DC lighting and refrigerators. This stage allows
for the charger to be used as a DC power supply.
- Stage 4 Maintenance: This stage is a
regular timed “return to bulk” stage. After 7 days of constant
operation in “float” the Enerdrive ePOWER Battery Charger will
switch the charger from float to bulk to agitate the batteries
electrolyte helping to provide an extended service life.
Bank 1 PRIORITY: Charge where you need it most
The ePOWER Charger delivers a priority charge to Bank 1, or your
main house battery bank which allows the charger to get this bank
recharged the quickest, then transition the cycle to the lesser
bank 2 & 3 batteries. The priority function also allows you to have
a battery chemistry different to the other two, such as an AGM
battery for house and lead calcium for your start banks. In the
event that all 3 banks are in need of a charge, an over-ride
function helps recover all 3 banks quickly and evenly before
switching back to prioritise on Bank 1.
It’s all about Lithium
Lithium batteries require a constant current / constant voltage
charge algorithm and are unique in that almost every amp-hour of
charge delivered by the charger is accepted as one amp hour into
the battery, hence the need to deliver a constant current as long
as possible. The
Enerdrive ePOWER Battery Charger
can be programmed for Lithium batteries. This setting delivers the
full rated output of the charger constantly with the charger
switching to power supply mode once the voltage peak is met
(indicating a full battery bank).
Display Panel
The
ePOWER Charger display gives you all the
information you need for the operation of your charger. At a
glance, key information such as charger amps, battery voltage and
charge state continually alternate on the screen.When in float /
power supply mode, the load amps are displayed so you can see
exactly what the charger is doing. The display also allows you to
program all settings of the charger, as well as activate the silent
mode.
Silence when you need it
By pressing the “SEL” button for 5 seconds, the ePOWER Charger
enters the ‘Silent’ mode that prohibits the fan from working. This
ensures totally silent and safe operation at night, ideal if the
charger is located close to your sleeping quarters. Silent mode
limits current output to no more than 50%, and is programmed to
remain on for 12 hours before automatically returning to a normal
‘fan-on & full output’ setting.
Enerdrive ePOWER Battery Charger Features:
- Multistage Charging: Fully automatic multistage battery charger
with the ability to charge 3 separate battery banks
- 20Amp will charge from small through to large 12v Batteries and
Battery banks
- Separate Battery Banks: Isolated charging design where battery
bank one is separate from battery bank two and three
- Programmable: Battery bank 1 can be programmed with a different
charge algorithm over banks 2 and 3
- Current Control: User adjustable current output (e.g. Dial the
60amp unit back to run off a 1kVA generator)
- Smart Charging: The ePOWER battery charger will regulate its
output based on the loads connected to your battery banks
- Wide AC Input Range: Operates on both 110V / 60Hz and 240V /
50Hz
- LED Display: Easy to use “set and select” menu along with
scrolling charger status
- Silent Mode: Disables the cooling fan for total silent
operation at night or whenever required. Activation reduces charge
output by half and locks out fan for 12 hours
- Temperature Sensor: Battery temperature sensor included with 3
meter cable
