IMPORTANT & SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS - This manual contains important safety and operating
instructions for power supply.
2. Do not expose power supply to rain or snow.
3. Use of an attachment not recommended or sold by the power supply manufacturer may
result in a risk of re, electric shock, or injury to persons.
4. Do not disassemble power supply; take it to a qualied serviceman when service or
repair is required. Incorrect reassembly may result in a risk of electric shock or re.
5. To reduce risk of electric shock, unplug power supply from outlet before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.
6. Never place marine power supply directly above battery; gases from battery will corrode
and damage power supply.
7. Never allow battery acid to drip on power supply when reading gravity or lling battery.
8. O/P CONNECTION PRECAUTIONS
Connect and disconnect DC output connections only after setting the power supply
switch to the off position.
GROUNDING AND AC POWER CORD CONNECTION INSTRUCTIONS — The plug must be
plugged into an outlet that is properly installed and grounded in accordance with al local
codes and ordinances.
DANGER — Never alter AC cord or plug provided — if it will not t outlet, have proper
cord installed by a qualied electrician. Improper connection can result in a risk of an electric
shock.

Introduction
All new Current Mode switching design offers increased power and reliability in a compact
package. Extra input and output ltering reduce EMI to extremely low levels. Reliability
features include an input fuse, thermal shutdown, current limiting and output short circuit
shutdown with automatic recovery. The model BCA1505MW-24 Power Supply supplies 24
VDC from a 110 or 220 VAC power source.

Specications
This unit comes with a carrying handle. The unit complies with the IP66 Standard.
In a DC UPS ( Un-interruptible Power Supply ) , the charger simultaneously powers the DC load
as well as the battery. As long as the AC power to the charger is available and the charger is
working normally, the charger will supply the DC load as well as charge / oat the battery. In
case the AC power fails or if the charger stops working, the battery will automatically power
the DC load. As soon as the AC power to the charger is restored, the DC load will once again
be fed by the charger and at the same time the battery will be recharged.
CAUTION! Please ensure that the sum of the current drawn by the DC load and the current
desired for charging the battery is less than the maximum current capacity of the charger. To
use as a DC UPS, rst switch off the DC load and connect it to the battery. Now connect the
battery. Switch on the charger and then switch on the DC load.

Installation
MOUNTING
Mount the unit and allow at least 4 inches of clearance around the heat sink ns for adequate
cooling.
POWER CONNECTION
The unit is supplied with power leads about 8 feet long. This should normally be adequate to
connect to a source of power. If you must extend the power leads, be sure to use at least a
good quality (typeTEW) AWG 8 gauge wire. The wire colours are:
Operation
Once you have decided on the charging prole you must set the switch to the correct
position. Set the switch to the correct position as shown on the label.
To turn the unit on, simply move the power switch to the ON position. The alarm buzzer will
sound and the Low Output LED will come on briey, and then the green OUTPUT ON LED will
illuminate.
When the unit is rst turned on, it will charge the batteries at a constant current and
the charging light will be on. After a period of time, which may be minutes to hours, the
batteries will reach the oat voltage at which time the charging light will go off, and the
charging current will reduce as necessary to maintain the batteries at that voltage. You may
check this voltage at the output terminals of the unit with a good digital voltmeter.
110 VAC
Black/Brown - AC Hot
White/Blue - AC Neutral
Green - Ground
All connections should be made inside an appropriate junction box. The maximum current
draw from the 110 VAC supply is 14 amps, so a 20 amp circuit breaker should be used in the
circuit panel.
The unit is supplied with two AWG 8 gauge wires. The red wire is the output positive. The
black wire is the output negative.

This charger features user selectable 2 or 3 stage charging. The charging prole is selected by
turning the switch on the front panel to 3 stage or 2 stage charging.
A two-stage charger provides a constant current until the battery reaches its rated capacity
and then switches to a “oat” voltage. The current then reduces as necessary to maintain
the battery at the oat voltage. The charger can be connected to the battery indenitely and
will provide the appropriate prole. A two-stage charger is recommended in most instances
since it is the most versatile and can be permanently connected to attenuate the characteristic
discharge of unused batteries. A load can be put on the battery or batteries without altering
its ability to keep the battery at optimal charge.
A three-stage charger is the fastest charger. It charges the battery at a constant current
until the battery voltage reaches a slightly elevated level. The battery is maintained at
this voltage while the charging current diminishes to a low value, and then the battery is
switched to the oat voltage where it can be maintained indenitely. However, the charger
cannot differentiate between a current going to a load on the battery, or being absorbed by
the battery, so it can overcharge a battery supplying current to a load. A two-stage charger
is preferred for “loaded” batteries and a three-stage for idle or unloaded batteries during
recharging.
All of Analytic Systems’ chargers include adjustable output voltage for charging standard or
deep cycle lead-acid, VLRA or gel type batteries.

BATTERY TEMPERATURE SENSOR
The battery temperature sensor can be connected to the charger to allow temperature
compensation of the battery charging voltage (1 is supplied with the unit).
The charger will work without the battery temperature sensor.

Troubleshooting
This unit provides LED indicators and a buzzer to help diagnose any problems. The unit
should sound the buzzer to alert you prior to shutting itself down. You should immediately
check the indicators to determine the cause of the shutdown.
CHARGING Indicates that the battery charger is charging the batteries:
If the LED is not on, the batteries may be fully charged and the
charger is supplying a oat voltage to the batteries to keep them
fully charged.
LOW OUTPUT Indicates that the output voltage is below normal because:
The current demanded by the devices connected to the unit
exceeds the maximum output current rating, causing the output
voltage to drop to maintain the current at the maximum level,
The input voltage is not high enough for unit to operate,
LOW INPUT Indicates that the input voltage is below normal because:
The input voltage is not in the correct range for proper operation of
the unit.
OVERTEMP Indicates that the Battery Charger is running too hot because:
Too much power is being drawn, turn off or unplug some devices.
The Battery Charger is located in a poorly ventilated area.
If the load exceeds the continuous rating for too long a period, the
temperature sensor inside the unit will turn off the outputs. After
the unit cools sufciently, it will automatically come back on. If this
happens frequently, remount the unit for increased airow so it
cools better.
