OPERATING PRINCIPLE
The shore-power units allow to get in a single cabinet the 230VAC on-board protection and a battery
charger.
The shore-power units housings meet the European on-going rules. Compact and lightweight, they
provide practical entry for the cabling that reduces mounting time.
The user protection is insured by a 16A/30mA differential circuit breaker. The on-board utilisation
outputs are protected by 2, 3 or 4 10A DPN thermo-magnetic circuit breakers.
The design of the shore-power units in the CPS2 range is based on a high-frequency split converter that
transforms the AC signal into regulated and filtered DC current. They can operate as battery chargers
on a DC power supply.
Once the type of battery and type of charge has been selected, operation of the shore-power unit is
entirely automatic. It can remain connected to the batteries and does not need to be disconnected when
starting up an engine (marine application), because it is equipped with rectifier diodes.
The appliance's output voltage is sufficient to recharge 1, 2 or separate 3 batteries (integrated charge
distributors, separation of batteries). All models feature an output suitable for recharging an engine
battery (BAT D output, marine application). The charger's maximum output is the rated current
distributed to each output according to the batteries' usage needs.
Each output can deliver the rated current.
Not all the outputs have to be connected. However, if only one output is used, we recommend
interconnecting outputs BAT1, BAT2 and BAT D to one another (optional).

SWITCH SETTINGS – ADJUSTMENTS - INDICATORS
3.2.1 Description
The CPS2 shore-power units are equipped with switches allowing you to set up the charger according to the
type of batteries and the application. CPS2 chargers feature the Boost function for faster recharging. This
function is controlled by a timeout (4 hours +/- 10 minutes) and is automatically inhibited when the battery is
fully charged: stoppage of the boost for I batteries < 15% of I rated charger.
The Boost function can also be disabled by means of a switch.
