MBC BATTERY CHARGER SERIES BATTERY CHARGER

The long experience we have in the nautical field has given us the ability to evolve the range of MBC
battery chargers, now called MBC BATTERY CHARGER, with superior performance to those currently on the
market. The high level of performance of the MBC BATTERY CHARGER gives a charge to the batteries which
is both fast and safe.

Other important advantages which the MBC BATTERY CHARGER battery chargers offer, are:

• Three stage IUoU battery charging.

• Multiple outputs in order to charge more groups of batteries (internal battery isolator diodes).

• Charge selector for liquid/gel electrolyte batteries.

• Low residual fluctuation on output (ripple lower than 30 mV RMS).

• Compatible with every kind of generator.

• Short circuit, overloading, output overvoltage and overheating protection.

• Can work in a wide range of ambient temperatures.

INSTALLATION

BEFORE USING THE BATTERY CHARGER CAREFULLY READ THIS USER’S MANUAL. IN CASE OF
DOUBT CONTACT THE “STUDER INNOTEC” SUPPLIER OR AFTER SALES SERVICE DEPARTMENT.

THE BATTERY CHARGERS HAS BEEN DESIGNED FOR FIXED INSTALLATIONS (FOR INDOOR USE
ONLY).

“Studer Innotec” battery chargers have been designed and made for the reasons described in this
user’s manual. The “Studer Innotec” Company does not accept any responsibility for direct or
indirect damage caused by improper use of the equipment, bad installation or by possible errors
occurring in this manual.

THE OPENING OF THE BATTERY CHARGER BY UNAUTHORISED PERSONNEL MAKES THE
WARRANTY VOID.

THE PACKAGE CONTAINS: battery charger - warranty card - user’s manual - cable terminals (to be

used for connection to the output terminals).

CHARACTERISTICS AND INSTALLATION

GB

INSTALLATION SITE

Install the battery charger in a dry and ventilated place and as near to the batteries as possible. The
battery charger, although having high efficiency, develops a certain amount of heat during function­ing, therefore, it is imperative that the installation area has sufficient ventilation, enough to allow use
of the equipment at maximum power.
The battery charger can be installed in a horizontal or vertical position with cables coming out in the
downward position. The vertical position is recommended because the natural convection of heat
helps to cool the equipment. The perimeter of the battery charger (except the base) must be kept at
a distance from walls or objects by a minimum of 5 cm.

FIG.1

The cables connected to the output terminals have a maximum length of 4 metres.

WARNING: the battery charger must be used only with a re-chargeable lead/liquid
electrolytic batteries or lead/gel (sealed or non-sealed).

WARNING: the outer surface of the battery charger is used as a heat sink, therefore it may
reach very high temperatures (risk of burns). Leave the equipment to cool down before
handling it.

EQUIPMENT REQUIRED FOR INSTALLATION

On the basis of the type of model, use the batteries and cables on the output terminals as specified
in the following table:

INSTALLATION

GB

BATTERY

WARNING: during charge, batteries can generate explosive gases, therefore avoid sparks or

naked flames. Provide adequate ventilation to the battery area whilst charging.

WARNING: before connecting the batteries check the terminals of the cables from the bat­tery. Reversing the terminals could seriously damage the battery charger even if protected by
fuses.

The positive terminal of the battery or of the group of batteries must be connected to one of the posi­tive terminals of the battery charger. The negative terminal of the battery or of the group of batteries
must be connected to the negative terminal of the battery charger. To make the connections use the
cable terminals supplied with the equipment.

EQUIPMENT SUPPLY

The equipment already includes a power cable for AC supply. For connections to an AC supply see
fig.2. Before powering up the battery charger check that the power supply voltage, described on the
rating label, corresponds to that supplied by the AC supply source.
In the electrical circuit a two-pole switch must be installed for the sole use of switching the equip­ment ON & OFF.
The insulation between the contact points of the connections of the AC supply must be at least 3 mm.
The connections to the AC supply must be carried out according to local electrical codes.

WARNING: before connecting or disconnecting the cables from the electrical terminals of the bat­tery charger, make sure that the equipment is disconnected from the AC mains and the batteries.

WARNING: in cases where the power cable could be damaged, have this changed by a “Studer
Innotec” service centre. In order to avoid accidents, the equipment must only be opened by au­thorised personnel.

SELECTION OF THE CHARGING MODE

The battery charger can be set to optimize the charge according to the type of battery used, either
liquid or gel electrolytic. The selection of the type of charge is made via the switch placed in the ter­minal board area, as indicated in Fig.3a.
When charging liquid electrolytic, re-arrange the switch to position EL, for batteries with gel elec­trolytic to the position GEL.

WARNING: check the charge mode. Incorrect selection

could cause shorter battery life or lengthen the char­ging time.

FIG.3 a

If the installation has only one or two groups of batteries, always connect the output marked “MAS­TER”. This is the main outlet of the battery charger.
If the “MASTER” is not connected, the battery charger may supply an output voltage lower than rated.
It is advisable to connect the group of batteries which are used more often (typically the service
group) to the MASTER output terminal.

The positive output terminals which are not used must be kept free (do not bridge the terminals).

WARNING: the use of inadequate size cables and incorrect connection of the terminals or
electrical joints may result in dangerous overheating of the connecting terminals or cables.

OPERATING

GB

BULK phase (constant current) - The batteries need more current than the battery charger can sup­ply. Current is limited to the maximum rated output. The battery charger can enter this phase during
start-up, when the batteries are low or when a high load is connected.

ABSORPTION phase (constant voltage) - The battery charger charges the batteries at a constant
ABSORPTION voltage and at the current they need.
The current needed by the batteries will tend to diminish over time. When the required current is less
than 20% of the maximum output value, the charger will change to the FLOAT phase.

FLOAT phase (maintenance) - The battery charger charges the batteries at the constant FLOAT volt­age. In this phase, as the batteries reach maximum capacity, they will tend to absorb current close to
zero Ampere. This FLOAT phase will allow the batteries to be on charge without the risk of overload­ing. The next step to the ABSORPTION phase occurs when the demand for current goes over 20% of
the maximum output value.

CHARGING CHARACTERISTICS

Charging occurs in 3 phases:

OPERATION

When the battery charger is switched on, it automatically selects the optimum charge mode to
best suit the batteries or load connected. The battery charger has a loading characteristic of the
IUoU type.
