BCD305 DC Battery Charger
The BCD305 battery charger provides up to 300 watts to charge a 12V or 24V
battery system (1 or 2 banks) from a 12V source. Both the 12V source and the
batteries under charge must share a common ground.
This all-new single board design incorporates state of the art switchmode
technology for unmatched efficiency and ultra-quiet operation. Multiple stages
of filtering reduce radiated or conducted noise to very low levels. Extra
features include adjustable output voltage, audible and visual indicators for
low input voltage, low output voltage and over temperature.
Safety features include reverse input protection, over-temperature shutdown,
current limiting, short circuit protection with automatic recovery, input
undervoltage shutdown, reverse battery protection and output overvoltage
crowbar.
Available options include a remote control and/or extra-wide temperature. We
are confident that you will get many years of reliable service from this Battery
charger.

* The Actual charging rate depends upon the input/output voltage ratio.
To obtain the charging capability at any given input voltage, use the following
formula:
Charging Current = Input Volts/Output Volts x 26
For example, 11 VDC in and 13.6 VDC out,
the charging current = 11/13.6 x 26 = 21.0 amps
