Introduction
Invertek Battery Charger is small and lightweight charger that offers charging patterns
which are perfectly adapted to each battery technology (liquid electrolyte, gel electrolyte,
lead calcium, etc... ). A charging pattern may be factory set to suit your specific
application. To prolong the life of your batteries and conserve their initial capacity, the
charger is programmed with 5 three-state charging patterns:
zBOOST Charge/FAST Charge :Restores battery capacity until 80 % in a short
space of time.
zABSORPTION Charge/BALANCE Charge : Complements of charge until 100 %
of battery capacity
zFLOATING Charge/TOP-UP Charge : Compensates for constant battery drain,
while keeping the battery fully charged.
Invertek Battery Charger is the only charger on the market to allow the battery to be
connected and used constantly, while still offering a real BOOST (high voltage) charge
over short period. The charger switches back to top-up mode automatically.
In accordance with EC standards, the Invertek Battery charger is fitted with a PFC
(Power Factor Corrector) which limit peak current draw from the input power required
from the generator or Mains supply to be reduced.

Advanced Charging Technique
Charging curves of the 3-state IUU type, with a boost phase and a floating phase.
The 3-state charging characteristic, used on boats everywhere, saves on charging time. In
addition, the charger can be adapted to all types of battery thanks to its 5 integral
charging curves supervised by a micro controller. Charge cycle starts on with the mains
power-up of product.
BOOST/Fast Charge
Charging continues at constant current (charger Inom) until the battery reaches the
maximum boost voltage. This voltage is maintained until the charging current falls to
Inom/8 ~Inom/10 boost charge over short period (12 hours) from the mains power-up of
product. This phase makes it possible to supply the maximum amount of energy in the
least possible time.
FLOATING/Top-Up Charge
The charger supplies just the current necessary to keep the battery at a constant and stable
voltage (floating voltage). This charging mode allows 12-volt equipment to be used
continuously (water pump, refrigeration, auto pilot, radio, lights, etc.) without the
batteries discharging.
It means that the on-board circuit can be used while keeping the battery charge level
constant. WITHOUT BATTERY AND IN SPECIAL CIRCUMSTANCES, THE
INVERTEK CHARGER SUPPLIES STABLE VOLTAGE.

Safety Devices
Electronic protection against:
- Output short-circuits
- Battery discharge in the event of mains failure

Disjonction protection against:
- Battery overvoltage or undervoltage
- Battery or charger overtemperature
Protection by fuses against :
- Mains input overload
- Battery polarity inversion
Anti-corrosion
Casing in aluminum with anti-corrosion paint.
Anti-impact
Resistance to impacts in normal use thanks to the 1.8 mm-thick casing (1,5mm for the
cover).
Ventilation
If the internal charger sensor exceeds 45°C, the fan starts. If the internal charger sensor
decreases to 40°C, the fan stops.
Options
1. Battery Temperature Sensor (BTS):
Sensor is used to balance charging voltage according to temperature gaps, compared
with reference temperature 25°C. If temperature exceeds 45°C, pre-alarm starts and
LED of BTS OH flashes. If temperature exceeds 50°C, charging stops and BTS OH is
lit on. Charging restarts when temperature is less than 50°C.
Procedure of connecting BTS is:
1. Disconnect the charger from the mains (MANDATORY). To avoid short-circuit,
disconnect the batteries.
2. Extract fixing screw from wires cover and remove it
3. Connect the sensor connector to the green terminal on the PCB. (See figure A)
4. Connect charger to the mains
5. Fix the temperature sensor(s) on corresponding battery(ies) with double-sided
adhesive tape supplied with sensor.
To disconnect sensor from the charger, charger must be disconnected from the mains
before (even if the charger indicates a default).
CAUTION: In case of fault, charger switches off automatically. Disconnect charger from
mains then wait for approximately 10 minutes before starting it again.
2. Remote Control: It can be connected to the Invertek charger. All operating controls
and displays are available on the remote control unit.
Safety Instruction
A battery can generate gas in the case of high overcharge, that can be explosive.
Attention must be paid to produce no spark or flame near a battery on charge, arrange for
a well-ventilated room.
Invertek charger limits overcharges and reduces this risk.
zExcessive discharges are among the principal causes of premature wear.
Invertek charger prevents such excessive discharge. After every discharge, (especially

5
higher than 50%), recharging should not be deferred for a long time.
zLow and permanent overcharge is another cause of premature wear. The Invertek
Charger delivers the current necessary for battery charge and adapts itself to supply
the optimum end of charge.
zThe accidental and violent overcharge or higher end of charge current produces early
destruction by excessive rise of temperature. The temperature should not exceed 50°C.
By the regulation of the current, the Invertek protects the battery from the temperature
rise at the end of charge.
It is advisable to
zPut batteries in a well ventilated area
zNot to smoke near batteries
zTake the battery manufacturer prescriptions into consideration
Accidental Leakage Current between Line And Earth
zConnections will be realized by an electrician or a professional installer.
zThe charger must be connected to a system having a two-pole differential circuit
breaker with 30 mA sensitivity.
Accidental Leakage Current between Charge Circuit and Earth
zTo detect accidental leakage currents to earth, you must use a safety device outside
the charger.
zThe rating and nature of the protection must be ensured by the installer.
zSpecial precautions are recommended on any installation where there is a danger of
electrolytic effects.
zRegulations require the presence of a battery cut-out on the output + pole and on
the output – pole.
Precautions Regarding Lightning Strike
In geographic zones exposed to a high risk of lightning strikes, it may be recommended
fitting a lightning conductor on the inlet side of the charger. Rich Electric will not take
charge of damaged caused by lightning strike.
Precautions Regarding Electromagnetic Interference
zMake sure the length of the cables and screening connections are kept as short as
possible.
zSeparate the power supply cables from output cables.
zCables must only carry the charger power supply. Branch or bridging connections in
order to supply another equipment are too be banned.
Installation
The location of the Invertek charger must be chosen by the following criteria:
Protection from unauthorized handling.
Dry dust free room, no condensation, no rodents.
Keep ventilation holes free. The ventilation of the Invertek is designed in such a way that
it will work most efficiently when mounted horizontally.
Before any connection, put the switch on the right charging curve.

Instruction of Charging Curve Selection (4 Battery Types and 1 User
Define)
Every battery is designed according to particular technology and therefore calls for a
particular charging curve.
With Invertek battery charger, you can achieve this perfect match between battery and
charger using a switch, which is simply positioned according to the required, charging
curve.

Note: Do indicate the type of your battery when buying the charger, and position the
switch correctly before use.
The user can very easily adapt the Invertek charger to the type of battery by rotate switch
used.
To modify configuration, carryout the following steps:
STEP 1: Disconnect charger from the mains. To avoid short-circuit, disconnect the
batteries.
STEP 2: According to 4 different battery types and desired charge current (30%, 70% and
