Introduction
The BCA1505 AC source battery charger provides up to 1500 watts of precision charging
power to charge your one or two bank battery system from a 110 or 220 VAC source. The
batteries must share a common ground.
The recently-updated single board design incorporates time-tested switch-mode technology
for unmatched efciency and ultra-quiet operation. Multiple stages of ltering reduce radiated
and conducted noise to MIL461 levels. In the absence of a battery, the BCA1505 can also be
used as a power supply up to its continuous current rating.
This unit features output voltage adjustment and user-selectable charging proles to ne-
tune its charging capabilities in order to suit your specic needs. The voltage temperature
compensation and equalize cycle functionalities help maintain and protect your expensive
battery bank systems, maximizing their lifespan.
Safety features include both charger and battery over-temperature shutdown, current limiting,
short circuit protection with automatic recovery, input under voltage shutdown, output over-
voltage protection and battery reverse connection protection.

Installation
MOUNTING
Mount the unit in a DRY and WELL
VENTILATED location with at least 4 inches
of clearance all around it.
There is 1500 volts of isolation between
the input and output, and the input and
case. There is 500 volts (1500V for 48V
output units) of isolation between the
output and case. Therefore, the unit may
be mounted on any surface without fear of
electrolysis or ground fault
CAUTION: The power switch must be in the OFF position before making connections.
When connecting the battery to the unit a small arc can form between the connectors. To ensure
spark-free connections, make connections only when the power switch is in the OFF position.
All connections should be made inside of an appropriate junction box with appropriately rated
circuit breakers used in the circuit panel to feed power to the BCA1505. See Specications for
the maximum input current and recommended fuses.
AC INPUT CONNECTION
This unit is equipped with a 5-foot (2.5m) power cable terminating in a NEMA 5-20 Connector
(for North American models) or a CEE7/7 Connector (for European models) to serve as an AC
Input Connection.
If you must extend the power cable be sure to use a 3 conductor grounded type extension
cable. For hard wiring to a source of power, cut off the plug, and strip the wires as necessary.
The wire colors are as follows.

DC OUTPUT CONNECTION
This unit is equipped with two pairs of Phoenix VDFK Through Panel connectors to serve
as Output Battery Connections. Use wires of an appropriate gauge for the expected output
current to make this connection. #6AWG wiring is the recommended size of wire to use for this
connection.
Ensure that the total average load connected to the batteries does not exceed the unit’s
charging amps. See Specications for this unit’s charging amps. See Specications for more
details regarding these values.
The wiring of this connection can be found on the unit’s front panel label and is as follows:

NOTE: This Single Bank Connection wiring arrangement is mandatory
for charging a 12 volt battery bank.
Connector Colour Wiring
Black DC Negative
Red DC Positive
This connection can support charging up to two battery banks that share a common ground.
If you are only charging one battery bank, you may connect both of the BCA1505G’s positive
outputs in parallel to the battery’s positive terminal in order to reduce stress on each individual
output connection.
CAUTION: Do not reverse connect the battery in the reverse polarity!!
This will activate the battery reverse connection protection which will blow the output
fuses inside the unit in order to protect the battery. The unit will be inoperable until these
fuses have been replaced.

• The battery is charged at a constant
current (higher than in two-stage)
until the battery’s voltage reaches
the absorption voltage.
• Then the charging current
diminishes as necessary to
maintain the battery at that voltage.
• Once the current drops to 10%,
the charging cycle is complete.
The unit switches to keeping the
battery at the oat voltage and will maintain the battery at full charge until needed.
• Three-stage charging is faster than two-stage, however the battery is subjected to higher
voltages and currents. Three-stage charging is not recommended for charging loaded batteries
because the unit cannot differentiate between current going to a load connected to the battery
and current being absorbed by the battery; this can cause overcharging.

Charging Proles
This unit has both two-stage and three-stage charging capability. You can choose which
charging prole is used during operation by using the Stage Select switch on the front panel.
Below are explanations of the two proles:
• The battery is charged at a constant
current until the battery’s voltage
reaches the oat voltage.
• Then the charging current
diminishes as necessary to
maintain the battery at that voltage.
• Once the current drops to 10%, the
charging cycle is complete. The
unit will maintain the battery at
full charge until needed.
• Two-stage charging is gentler on the battery since the battery is subjected to lower voltages
and currents than in three-stage. In addition, a reasonable load can be connected to the
battery without affecting the charger’s ability to keep the battery at full charge.
