2System Description
DC Power Supply Operation Mo e
f the equipment is being ordered as DC Power Supply, then the unit supplies a limited voltage and
current value that is adjusted from the front panel to the connected DC load. The output voltage and
current limits can be easily adjusted separately from the SETT NGS menu on the LCD panel.
Battery Charger Operation Mo e
The equipment that is ordered as battery charger has the following specifications. This operation mode
has 4 graduated charging level depending on the battery type. These are initial charge, float charge, boost
charge and temperature or auto controlled charging types. The charge voltages
per cell ;
for initial charge: 2.04V, for float charge: 2.23V, for boost charge: 2.375V, for temperature controlled
charge ; 2.17V at 0
0
C / 2.29V at 50
0
C. These are factory set values, and temperature controlled values can
be set from front panel according to the battery type.
LVD ( Low Voltage Disconnector ) can be included to the unit as an option. This function protects the
batteries from deep discharge by disconnecting them from output during battery mode when the mains is
absent.
Additionally, the dry contact alarm card is an optional feature with its automation functionality.

NFOCHARGER 3
Input an output EMI filters
These filters prevent electromagnetic interference between nfocharger, mains and loads. (EM –
electromagnetic interference)
Your battery charger and loads are protected against high voltage.
Power Factor Correction
When the power factor is 1, all the energy supplied by the source is consumed by the load
DC / AC Inverter
The inverter helps to obtain a very constant AC voltage level at the output by using DC voltage at the boost’s
rectifier output.
Rectifier
This unit draws on the mains the power required to supply the inverter and to recharge the batteries. The
alternating input voltage is rectified and distributed to the batteries.
Low Voltage Protection(Optional)
This type of protection is used as optional to prevent the deep discharge of the loads in the absence of the
power at mains, and this voltage level can be adjustable at the front panel.
Your Battery Charger’ features an benefits :
Feature Benefit
PWM technology
Transformerless design Compact design, small dimensions and low weight
Microprocessor controller To use all the sources in optimum level.
To observe carefully the failure conditions
PFC technology
High input power factor
To consume low reactive power
Not to load the installation extra (cables, transformers, generators
etc.)
Clean power for the mains.
Wide input voltage tolerance
(on-line operation even the mains is
between 80 – 280 V )
This helps to reduce battery usage and guarantees battery to be fully
charged and extends the battery life time.
On-line double conversion
topology
The output voltage of the nfocharger is DC. nfocharger input total
harmonic distortion is very low. This is very important for both the
systems and batteries which are supplied by nfocharger.
Temperature Management To calculate overloading time in a reliable way.
To protect against over temperature.
Effective output voltage regulation : (output voltage is not affected by changes on the mains input and load level.)
High efficiency ( low power consumption)

requirements (if any).
n standard battery charger the output voltage and frequency can be adjustable between 0-30Vs and
60-135Vs .
3r 1 Han ling
f needed to move the battery charger, it is obligatory to pack the unit. t is suggested to keep the
original packing.
3r 2 Storage
Please store the battery charger in an environment where the temperature is between –15 °C and +55 °C no
receipt of direct sunlight, far from the heating, in a dry place. Environmental humidity must be between %20
and %95 (non-condensing).
3r 3 Positioning
nfocharger and battery cabinet(if any) have to be positioned in an environment;
•No irect sun access,
•Must be ry,
•Far from the heating equipments
•No excessive ust
•Well-ventilate
•In or er to maintain a equate ventilation of Infocharger an battery cabinets (if
any), ensure the air vents are not blocke an leave at least 20 cm space at the rear
si e of the unit for ventilation.

3r 4 Connections
Connections must be done by authorized technical service staff. Life risk for user!
Temperature changes such as from cold to hot environment can cause condensation. t is dangerous
to operate the nfocharger. Please wait at least two hours before making the connections.
Connection terminals are in the rear side of the battery charger. Please take out the cover of the rear side to
make the connections.
Standard nfocharger connections are shown below.
Please follow the instructions as explained below.
3r 4.1 Groun (Earth) Connection
nforcharger ground (earth) connections have to be done.
The input ground clemens of the nfocharger should be connected to a reliable (low resisted) ground
The grounding connection of the loads can be done over the output grounding contactor.
The grounding connection of the external battery cabinet(if any) should be done over the same battery
grounding contactor.
The connection between the grounding unit of the nfocharger and the ground can be made according to the
minimum cross-sectioned cables which are given in the technical specifications table below.
3r 4.2 Input connection
The connection between the distribution frame and nfocharger for phase, neutral and ground are explained
as below
For single phase the R, Neutral and ground must be connected to their contactors in the front panel with a
1.5 mm
2
cross-section multi-vein cable
For three phase the R, S, T, Neutral and ground must be connected to their contactors in the front panel with
a 1.5 mm
2
cross-section multi-vein cable
Changes on distribution panel have to be done by authorized persons only.
3r 4.3 Battery connection
The batteries must be connected to the L+(positive) and L-(negative) points properly. The DC power supply
type nfocharger does not have this connection. The batteries have to be connected with an external circuit
breaker.
3r 4.4 Output connection
The clemens on the equipment can be used for the + and – output points. The cables to these clemens are
connected to the fuses and the protection is over the (L+) point.

4Switch On an Switch OFF proce ures
4th1 System Switch ON
After making all the connections mentioned in the previous chapter, you need to switch on to all the
automatic fuses on the front panel, if mains voltage is within the limits, the unit switches on.
nforcharger makes self-test for few seconds to check if everything is normal, and then starts to charge the
batteries or supply the load.
4th2 System Switch OFF
To stop the load to be supplied or the batteries to be charged, please switch off the all automatic fuses in the
front panel.
