20 AMP, DC TO DC BATTERY CHARGER
WITH SOLAR INPUT

FEATURES
Matson MA20DC and MA20DCS
• Designed to boost the low voltage found at the end of long
cable lengths to a useable level so your Auxiliary battery can be
recharged to 100%.
• Three (3) Stage smart charging which comprises of BOOST,
ABSORPTION and FLOAT ensures simple yet optimal charging.
• This charger range has been built tough for Australian
conditions. Rated at IP65, the charger is resistant to dust and is
splash/rain proof.
• Electronically protected against user error, the charger will not
damage vehicle electronics.
• Short circuit and reverse polarity protected.
• This charger is micro-processor controlled to protect against
overcharging the auxiliary battery and ensures the donor battery
is not discharged below 12.2 volts. This will ensure the donor
battery is left with enough voltage to start the vehicle.
• Chemistry selectable: the operator can select the appropriate
settingtomatchthespecicchemistryofyourauxiliarybattery.
GEL, Calcium or AGM/DeepCycle/SLA. This feature, unlike
other units on the market, allows you to change chemistries at
the push of a button. Once selected, the charger remembers the
chemistry selected, no matter what happens, until the operator
selects a different chemistry.
• Microchip monitoring, management and control.
• Electronic touch-button selection.
• Inbuilt overheating protection.

• Inbuilt over charge protection. Charger will automatically reduce
current (amps) as required to optimise battery charging.
• The charger has been designed to recommence charging from
oatmodewhenaloadisplacedontheauxiliarybattery.i.e.if
auxiliarybatteryisfullychargedandthechargerisinoatmode,
thechargerwillrecommenceit’schargingcycleautomatically
when the auxiliary battery is used again.
• Can be used with either Fixed or Variable voltage alternators
(with outputs above 12.2 Volts)
WARNINGS
• Before connecting the charger ensure you have read the
instruction manual in full.
• Explosive gases may escape from the battery during charging.
Keepawayfromamesandsparks.Ensureareaiswell
ventilated.
• Ensure charger is not immersed in water or exposed to
excessive dust.
• For charging 12 Volt batteries only.
• This appliance is not for use with non-rechargeable batteries.
• Ensure charger is placed well away from battery.
• This appliance should not be operated by children.
• Alwayscheckspecicationsofbatterymanufactureroncharge
rates and voltage prior to charging.
• Do not use the charger with damaged cable.
• Do not charge frozen battery.
• Before charging, make sure the input is within stipulated rating
level, otherwise charging performance may be seriously affected.

INSTALLATION INSTRUCTIONS
• Install the charger in a suitable location within the vehicle,
although the charger is splash resistant we recommend it to be
placed in a dry area.
• It is recommended that you locate the Charger no closer than
300mm and no further than 3000mm from the auxiliary battery,
but it should always be closer to the auxiliary battery.
• Secure the charger with brackets and screws provided.
• Output cables:
1. Connect the Red (positive) cable to the Red (positive)
terminal on the auxiliary battery.
2. Connect the Black (negative) cable to the Black (negative)
terminal on the auxiliary battery.
• Input cables:
1. Connect the Blue (Positive) cable to the Red (positive)
terminal on the main cranking battery.
2. Connect the Black (negative) cable to the Black (negative)
terminal on the main cranking battery.
3. SOLAR INPUT (MA20DCS ONLY) - Connect the Yellow
(Solar) cable to the solar panel. (Recommended 120Watt
regulated panel minimum) Once the input voltage from
the solar panel rises to 13.0v, the charger will commence
charging the auxiliary battery. The charging rate will depend
on the output current of the solar panels.
i.e. Watts ÷ Volts=Amps 120÷13=9.2Amps
• Check all electrical connections are secure and tight.

OPERATING INSTRUCTIONS
Once correctly installed the Matson MA20DC & MA20DCS chargers are
very simple. Just “set your Chemistry and forget”.
Charger Display:
• Red LED indicates “POWER” is on to the unit
• Green LED indicates the unit is “CHARGING” the auxiliary battery.
• Yellow LED indicates the auxiliary battery is “FULLY CHARGED” and
the charger has moved to a Float Mode.
• The battery chemistry selected is indicated by the Green LED.
First Charger Start Up:
• Start your vehicle and the charger, after a few moments, will
automatically recognise that there is a charge being applied to the
cranking battery. When the cranking battery reaches 13 volts the
charger will turn on and begin charging the auxiliary battery.
• Now it is time to select your battery chemistry. Press the “SELECTOR
SWITCH” until the LED is beside the correct chemistry setting for your
auxiliary battery.
• The charger will now memorise the chemistry setting and automatically
will make it the default setting when turned back on. If you need to
change the chemistry, repeat the instructions above. Remember the
charger will always default to its last setting.
• *NOTE- Once the main cranking battery falls below 12.2volts the
charger will stop operating and switches itself off. Alternatively if the
auxiliary battery has reached its desired charge level the charger will
STOP CHARGING and go to the yellow LED “FULLY CHARGED” and
the charger will move to a Float Mode.
Maintenance:
The charger is maintenance free. Note that if the charger is disassembed
by anyone other than a recommended Matson repairer, your warranty will
be void.
