IMPORTANT & SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS — This manual contains important safety and operating
instructions for the battery charger.
BATTERY CHARGER PRECAUTIONS
1. Do not expose the battery charger to rain or snow unless it is a sealed model.
2. Use of an attachment not recommended or sold by the battery charger manufacturer may
result in a risk of re, electric shock, or injury to persons.
3. Do not disassemble the battery charger; return it to the manufacturer or an authorized
service center when service or repair is required. Incorrect reassembly may result in a
risk of electric shock or re. Voltages in excess of 350 volts are present inside the charger
anytime it is plugged into an AC outlet, even if it is switched off.
4. To reduce risk of electric shock, unplug the battery charger from the AC outlet before
attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
5. Never place battery charger directly above battery; gases from battery will corrode and
damage battery charger.
6. Never allow battery acid to drip on the battery charger.
BATTERY SAFETY
1. WARNING — RISK OF EXPLOSIVE GASES
i. WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS
REASON, IT IS OF UTMOST IMPORTANCE THAT EACH TIME BEFORE SERVICING
EQUIPMENT IN THE VICINITY OF THE BATTERY, YOU READ THIS USER GUIDE AND
FOLLOW THE INSTRUCTIONS EXACTLY.
ii. To reduce risk of battery explosion, follow these instructions and those published by
the battery manufacturer and manufacturer of any equipment you intend to use in
vicinity of battery. Review the cautionary marking on these products.
2. PERSONAL PRECAUTIONS
i. Someone should be within range of your voice or close enough to come to your aid
when you work near a battery.
ii. Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
iii. Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
iv. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately ood eye with running cold water for at least 10
v. minutes and get medical attention immediately.

3
vi. NEVER smoke or allow a spark or ame in the vicinity of a battery.
vii. Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark
or short-circuit the battery or other electrical part that may cause a re or explosion.
viii. Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-acid battery can produce a short- circuit
current high enough to melt metal, causing a severe burn.
ix. NEVER charge a frozen battery.
x. If it is necessary to remove a battery from service, always remove grounded terminal
from battery rst. Make sure all accessories connected to the battery are off, to
prevent an arc when reconnecting the new battery.
xi. Be sure area around battery is well ventilated.
xii. Clean the battery terminals. Be careful to keep corrosion from coming in contact with
eyes.
xiii. Study all the battery manufacturer’s specic precautions such as removing or not
removing cell caps while charging and recommended rates of charge.
Medical Equipment Notice
Analytic Systems does not recommend the use of their products in life support
pplications where failure or malfunction of this product can be reasonably
expected to cause failure of the life support device or to signicantly affect its
safety or effectiveness. Analytic Systems does not recommend the use of any of

Introduction
The BCH10W Step Down series of Battery Chargers supply up to 10 amps of charging current
at 12, 24, 36 or 48 volts from any higher voltage between 20 and 80 volts DC in an IP66 rated
watertight and EMC shielded enclosure for use in automotive, heavy equipment, marine,
industrial, rail or alternative energy environments. The output voltage is congured to allow
permanent connection to the battery.
The standard BCH10W model offers a Deutsch connector on a pigtail input/output cable and is
designed to be water resistant to IP66.
The BCH10Y is an upgraded version with the same connections that is individually tested to
meet IP67.
The all surface mount high frequency design offers higher reliability, higher efciency (more
than 91%), more power (up to 544 watts at 48 VDC Out) and minimum size. Two LED indicators
show the presence of input power, and when the unit is charging (output current is greater
that 2 amps).
The unit has reverse input protection, reverse battery connection protection, output
overvoltage protection and features spark free connection to the battery. Smart Ideal Diode
output circuitry prevents any reverse current owing from the battery back into the converter.

Operation
To turn the unit on, simply turn on your source of power. The Input Power LED will illuminate
to indicate the presence of input power.
The BCH10 will immediately begin charging the battery. 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 and
the charging current will begin to drop. When the current falls to 10% of the rated charging
current, the charging light will go off, and the charger will maintain the batteries at the oat
voltage. You may check this voltage at the battery with a good digital voltmeter. As shipped
from the factory, the unit is preset to the oat voltage listed in the specications, which is
generally recommended for lead-acid batteries.

Mounting
Mount the unit and allow at least 1 inch
of clearance for adequate cooling.
Input and Output Connections
This unit is equipped with a watertight gland
and short 4 conductor pigtail terminated with
a Deutsch DT04-4P connector. The mating
connector is also supplied, but without
cable. The plug pin out is shown in the table
below.
PIN NAME DESCRIPTION
1 POSITIVE INPUT (red)
2 NEGATIVE INPUT (black)
3 NEGATIVE OUTPUT (black)
4 POSITIVE OUTPUT (orange)
Connect the input pins to the power source, and the output pins to the load, making sure
to observe the correct polarity of the connections. If the input is connected in reverse, the
protection fuse will blow, and must be replaced by the dealer or an electronics technician.

Troubleshooting
Consistent with military standards, this unit is normally manufactured using lead based solder.
However, this unit can be built to ROHS lead free standards, identied internally by a red
colored printed circuit board by adding the E option. This is a no charge option, but can add 2-4
weeks to the delivery of an order.
This is the same unit as the VHC10W, except each unit is individually tested to comply with
the IP67 rating of withstanding 1 meter immersion for 30 minutes with no ingress of moisture.
This unit provides LED indicators to help diagnose any problems.
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.
INPUT POWER Indicates that power is being received by the unit
If the LED is not on, check with a voltmeter that there is power at the
connections.
Check that the polarity is correct, Positive to Pin 1 and Negative to Pin 2.
If the power is reversed, the unit is not damaged, but the input fuse
must be replaced by a service technician experienced in Surface Mount
Technology.
