1 PRODUCT FUNCTION
The BCDC1225(-LV)/BCDC1240(-LV) is a three-stage, 12V DC-DC battery charger that
operates from an alternator input of 12V nominal or a 12V nominal solar panel input.
The BCDC1225/BCDC1240 will also charge from an alternator input from a 24V nominal
vehicle*

. The input voltage of the BCDC1225(-LV)/BCDC1240(-LV) can be above, below
or equal to the output voltage making it ideal for charging an auxiliary 12V battery
where the distance from the main battery may cause a significant voltage drop. The
BCDC1225(-LV)/BCDC1240(-LV) is also designed to isolate the main battery from the
auxiliary battery, to avoid over-discharging the main battery. The BCDC1225-LV and
BCDC1240-LV operate almost identically to the BCDC1225 and BCDC1240 but are
designed to operate from an ignition trigger to allow operation in vehicles with Variable
Voltage or Smart Alternators.
1.1 Display Panel
The front panel features 6 LEDs to display the charge profile and charge status.
LED State ‘Charge Profile’ LED ‘Charge Status’ LED
Off Unit has no Power Output is off
Blinking Unit is in Standby
Unit is supplying power
On Unit is on and can supply power
When blinking, the flash duty-cycle of the ‘Charge Status’ LED will increase to
reflect the amount of current being supplied - If the LED is ON solid, the unit is
supplying full power (e.g. 25A for a BCDC1225).
