2 Charger overview
2.1 General description
The InteliCharger 240 24 is an advanced, automatic, multi-stage battery charger using Switched mode
technology and Battery care philosophy, suited to meet the most advanced requirements of battery
manufacturers. The battery care concept is based on algorithms that implement automatic battery charging,
battery life optimization, flat batteries recovery and real time diagnosis. The real time auto-diagnostic system
monitors battery faults such as cells in short circuit, accidental reverse polarity connection, disconnection of the
battery. These faults can be easily detected and fixed by help of blink code of diagnostic LED during the charger
installation and operation. Charger is suited for all battery types. By jumper setting it is possible to change
parameters of charging curve for: Open Lead Acid, Sealed Lead Acid, Gel and NiCdNiMH battery type. A
rugged casing with bracket for DIN rail mounting provide IP20 protection degree.
Suited for the following battery types: Open Lead Acid, Sealed Lead Acid, Lead Gel and NiCdNiMH.
Protected against short circuit, reversed polarity, overload and over temperature.
Signal output terminal (voltage free contact) for discharged or damaged battery and charging fail signaling.
Signal output terminal (voltage free contact) for Mains power input fail signaling.
IP20 protection.

Note: For NiCdNiMH batteries end-of-charge is determined by negative V detection of battery voltage (-5
mV/cell). If no negative V but only a flat profile is detected fast charge is terminated after 10 min. General
end-of-charge timeout set to 16 h. Float charge current is regulated at 10% of max current corresponding to
trimmer position. In order to detect end-of-charge negative V, charging current must be set at least at 30% of
nominal battery capacity (0.3 C). With lower values of charging current negative V detection is not
guaranteed.
signaling the charger operates as usual and continues with charging the battery.
Note: It is essential to connect battery properly to ensure right results of battery life test function.
Battery care
The Battery Care philosophy is based on algorithms that implement rapid and automatic charging, battery
charge optimization, flat batteries recovery and real time diagnosis. The realtime auto-diagnostic system
monitors battery and charging proces during the installation and operation.Faults such as cells in short circuit,
accidental reverse polarity connection, disconnection of the battery, can be easily detected and fixed by help of
blink code of diagnosis indicator. The charger is suited for all battery types. It is possible to choose predefined
charging curves for Open Lead Acid, Sealed Lead Acid, Gel and NiCdNiMH battery. Battery reliability in time is
guaranteed by continuously testing the internal impedance status. It avoids any possible risk of damages and
grants also a permanent, reliable and safe connection of the battery to the charger. The system, through a
battery stimulation circuit with algorithms of evaluation of the detected parameter, is able to recognize batteries
with a short-circuited cell.
Charging curve
Automatic multi-stage operation and real time diagnosis allows fast recharge and recovery of deeply discharged
batteries, adding value and reliability to the system hosting the InteliCharger 240 24 device. The type of
charging is Voltage stabilized and Current stabilized IUoU.
Each of four charging stage is identified by a flashing code on the Diagnosis indicator.
To maintain the output battery voltage in lower levels, dont enable boost charging. (No jumper set in position 5.)
There are four charging stages:

The charger is equipped whit an internal fuse. If the internal fuse is blown, it is most probable that there is
a fault in the device. If happen, the device must be checked by manufacturer.
secondary side
o
The charger is electrically protected against short circuits and overload. Output current is electronically
limited.
Thermal behavior
Standard surrounding air temperature is up to 50C. For ambient temperature over this limit, the output current
is reduced by 2.5% per C. Maximum temperature is 70C. At the temperature 70C the output current will be
50% of nominal current. The charger does not switch off in case of ambient temperature above 70C or in case
of thermal overload. The device is protected for over temperature conditions worst case. In this situation the
device shut-down the output and automatically restart when internal temperature fall down into limits.

Rail mounting
The charger module must have a minimum vertical and horizontal distance of 10 cm to the other used DIN rail
modules in order to guarantee sufficient auto convection for proper cooling.
IMPORTANT: Depending on the ambient temperature and load of the charger, the temperature of
the housing can become very high!
