2.2.2 Block diagram

2.2.3 Principle of operation

The CPS range of battery chargers are designed on
the basis of a high frequency switching converter
which transforms the ac signal into a regulated,
filtered dc voltage suitable for charging accumulator
batteries.

2.2.4 Detailed operation

After the initial selection of input mains, type of
battery and type of charge, battery charger operation
is entirely automatic.
2.2.4.1 Selector operation
Mains voltage selector
The charger is fitted with an internal voltage
selector enabling it to operate on 2 types of Mains
supply :
European mains supply : 230Vac – 50/60Hz
Other mains supplies (USA, etc. ...) :
115Vac 50/60Hz
Battery type selector
The charger is fitted with an internal selector
enabling it to operate on 2 types of battery just by
changing a switch:
Lead/Antimony battery : "ANT"
Lead/Calcium battery : "CAL"
CPSDED
Charge type selector
The charger is fitted with an internal selector
enabling it to provide 2 types of charging just by
changing a switch :
Charge in Floating mode : "BOOST OFF"
Charge in Boost mode for 6 hours ± 30 minutes
then automatic switch to Floating mode :
"BOOST ON"
NB :
higher than the off load Floating mode voltage.
2.2.4.2 Operation of the indicators
These indicators are fitted on the charger front panel
and display the unit's mode of functioning.
"Mains present" indicator
This indicator is extinguished in the following
circumstances :
Absence or degradation of the ac mains supply,
Input fuse blown,
Internal malfunction of the battery charger.
Boost or Floating charge mode indicator
This indicator is extinguished in the following
circumstances :
Output fuse blown,
Absence of voltage at charger output (for
example, ac mains not connected).
The Boost voltage off load is about 5%
