B Description of battery charger
1 Technical description
The SLT 100 battery charger is designed
for the fully automatic charging and
recharging of lead batteries and is
equipped with a special electronic charging
system (1, 2). The rated charging current
specified flows at a charging voltage of
2.0 volts per cell. The battery must be
assigned so that the initial charging current
is approx. 16 Amperes per 100 Ah of
battery capacity.
The difference lies in the initial charging
current – see data plate (3).
Initial charging voltage: 24, 48, 80 volt
depending on type
Initial charging current: 20 A-160 A,
depending on type
The battery charger is protected on the
secondary side by a fuse (5) acting as
a short circuit protection and by a sensor to
limit the transformer temperature.
To ensure the operational safety of the
system, only self-cooled stacked silicon
rectifier elements (4) are used.
Stray field transformers (6) are used to
comply with the specified charging
characteristic.
The stray field transformers are equipped
with additional primary tapping to
DIN 41 774, corresponding to +10 %,
+5 %, 0 % and -5 % to allow for mains
voltage deviations.

Modifications should only be carried out by
the manufacturer’s service department.

For transport and assembly see chapter C
on page 5.
For chargers with electrolyte circulation the
air volume flow must also be adapted to the
battery, see "Air volume flow presetting” on
page 15.
5.1 Air volume flow presetting
Switch (3) has the following factory settings
for all SLT 100 large battery chargers:
6 Maintenance of the filter
The blue suction filter (5) on the bottom of
the pump must be checked for soiling at
regular intervals.
In strongly dusty areas, it is to be replaced
every 3 months, otherwise at least every 6
months.
To replace the suction filter (5) tip the blue
insertion sleeve to the side and replace the
polishing cotton.
