2.1.3.2 Current
The table below defines the maximum output current
at rated output power as well as the type and rating of
the carsocket type fuses placed in series with the
charger outputs.

12V 06A 6 A
24V 03A 3 A
12V 10A 10 A
24V 05A 5 A
12V 12A 12 A

2.1.4 Environmental specification

All chargers in the range meet the following
characteristics :
Storage temperature : - 20°C to + 70°C.
Operating temperature : - 10°C to + 50°C.
Humidity : < 90% non-condensing

2.1.5 Protection and operating safety

2.1.5.1 Input protection
The chargers are fitted with two pole protection by 2
fuses F1 and F2 whose ratings are given in section
2.1.2.
2.1.5.2 Output protection
Output protection is provided by a fuse placed in
series with the "–" terminal of the charger in order to
reduce the number of fuses. The rating and type of
this fuse are defined in the table in section 2.1.3.2.
2.1.5.3 Additional safety devices
All models are fitted with the following safety
devices :
Protection against input voltage surges by a
Varistor (275 Vac).
Protection against abnormal heating of the power
semiconductors.
Protection against polarity reversal (output fuse
blows)

model.
2.1.5.4 Fan Functioning
The chargers do not have any electromechanical fan;
they have a natural ventilation :

2.1.6 Options

The options do not form part of the basic battery
charger supply. They are available from your
reseller. The only extra options that could work with
the CPS chargers are the pieces of equipment
proposed as an option by CRISTEC.
Analogue voltmeter for displaying the charging
voltage at the input side of the charge
distribution diodes.
