P/No. IDC45

WARNINGS

• Explosive gases may escape from the battery during charging.
Prevent flames and sparks and provide adequate ventilation.

• Before charging, read the instructions.

• FOR CHARGING 12 VOLT LEAD ACID BATTERIES ONLY.

• Do not attempt to charge non-rechargeable batteries.

• Never charge a frozen battery.

• Corrosive substances may escape from the battery during charging and damage
delicate surfaces. Store and charge in a suitable area.

• This appliance is not intended for use by young children or infirm persons unless they
have been adequately supervised by a responsible person to ensure that they can use
the appliance safely.

• Fit fuses as close to the batteries as possible to protect the cable in case of
short circuit.

FEATURES

The IDC45 DC-DC charger is purposely designed for charging auxiliary batteries.

It includes all the features needed to maintain the auxiliary battery to its optimum
condition and to prolong the battery life.

SWITCHMODE TECHNOLOGY

The IDC45 converts your vehicle’s 12VDC/24VDC alternator power to the voltage

level allowing your batteries to be fully charged, prolonging battery life and
reliability. With the latest synchronous switching technology, efficiency of IDC45
exceeds 94% at typical full load condition.

DUAL INPUT OPERATION

Allows two energy sources to power the IDC45 simultaneously. Solar input takes

precedence if solar and alternator inputs are present. When solar input cannot provide
enough energy to the load, the IDC45 will draw power from solar and alternator
simultaneously.

SOLAR MPPT

The IDC45 utilises sophisticated MPPT (Maximum Power Point Tracking) solar

regulator technology. MPPT maximises the power generated from the solar panels
to the auxiliary battery.

SUPERIOR 3 STAGE CHARGING

Using high speed microcontroller and proprietary charging algorithm, the IDC45

delivers a sophisticated 3 stage charging process resulting in a faster and more
powerful charge, ideal for deep cycle batteries. The first stage, bulk (constant current),
charges the battery faster while the second stage, absorption (constant voltage),
ensures the battery is thoroughly charged. The final stage, float, maintains the battery
at a safe voltage allowing it to be maintained and ready for use indefinitely.

MULTI-CHEMISTRY SUPPORT

The IDC45 supports GEL, AGM, WET and CALCIUM batteries. If the calcium battery

mode is selected, periodic equalisation will be provided to the calcium battery for
removing acid stratification.

IGNITION CONNECTION

The ignition connection activates the lower input voltage operation to suit vehicles

with smart (variable voltage) alternators.

TEMPERATURE COMPENSATION

The IDC45 is supplied with a 2 metre temperature sensor. The sensor monitors the

battery temperature and adjusts (compensates) the charger’s output to prevent
overcharging. This is ideal for batteries used in warmer climates or environments.

REMOTE CHARGER STATUS INDICATION

A pink wire is provided for driving an external panel mount LED indicator (Eg Narva

P/No. 62090BL) to show the status of the charger. It shows whether the auxiliary
battery is on charge (Solid Colour) or the charger is in a fault condition (Flashing).

PROTECTIVE FEATURES

Spark-Free Protection

The IDC45 will not start charging the battery (no output) unless the load is securely

connected. It prevents the output leads from sparking due to accidental short circuit
making the charger safer to use around batteries.

Reverse Connection Protection

Reverse connection on input and output terminals does not damage IDC45 internal

circuit. The IDC45 detects reverse connection condition and indicates whether input
or output connection is reversed.

Over and Under Voltage Protection

The charger will automatically shut down if there is an over voltage or under

voltage problem.

Over Temperature Protection

The charger will lower its output current if the temperature of the unit begins

to overheat.
