Redarc have just released the
BCDC1225 in-vehicle battery charger. It is a three stage DC-DC battery
charger that operates from any input between 9 and 32 Volts DC &
is designed to charge any commonly used automotive battery to 100%.
The BCDC1225 features the same multi-stage charging algorithm as the
award winning BCDC1240 with an output regulated to 25 Amps. The lower
output current means the BCDC1225 is perfectly suited to small and
medium battery bank applications such as 4WDs, Campertrailers and marine
craft.
The BCDC1225 features a MPPT Solar Regulator, which can be used to
charge your auxiliary batteries when 12V is not present from your
vehicle. The MPPT Solar charging algorithm extracts the maximum
available power from your solar panels at any given time. The
BCDC1225 is also designed to isolate the main battery from the auxiliary
battery.
what is mppt?
MPPT stands for Maximum Power Point Tracking and
relates to the solar cell itself. Each solar cell has a point at which
the current (I) and voltage (V) output from the cell result in the
maximum power output of the cell. The principle is that if the output
from the cell can be regulated to the voltage and current levels needed
to achieve a power output at this point, then the power generated by the
solar cell will be used most efficiently.
MPPT ensures that you get the most power possible from your solar panels
during low light level conditions. All this calculation and regulation
results in the output from your solar regulator providing the maximum
current possible at the required voltage at any given point. During low
light level situations it will compensate for the low light level and
find the new point at which the solar cell delivers its maximum power
output.
alternator &
solar automatic switching
With the addition of Redarc's RK1260 relay kit you
can set up the BCDC1225 to automatically select between the best power
source. This means you can have a solar panel permanently mounted so
when you stop to camp & switch off the vehicle's engine, the relay will
select the solar panel.
display panel
The BCDC1225 has three battery type
settings available which enable optimal charging profiles for the
auxiliary battery. The battery type selected is displayed via the LEDs
on the front panel in the section ‘Battery Type’.
In addition to the battery type, the
status of the charger is indicated via three LEDs. The ‘Charging Status’
shows when the unit is in
BOOST, ABSORPTION or FLOAT.
In order to give more information, the applicable LED will flash to
indicate the output by the unit. The longer the flash, the more current
the charger is putting out. If the LED is ON solid, then the unit is
supplying a full 25A to the auxiliary battery.
Standby mode is entered when the unit is
not charging. In this mode, the battery type LED will blink approx once
per second, the charging status LED's will be off. In this mode, if the
battery type wire is moved then the selected battery type will update.
