Electrical characteristic of the dry contacts (relay) : cut-off characteristics 30V 100mA
Be careful: The monitoring of +BAT1 low battery voltage when it is activated, draws about 12mA
on the batteries bank connected on +BAT1 output.

CCESSORIES ET ACCESSORIES CONNECTIONS
The accessories are not bundled with standard CPS3 battery chargers; they are available from your reseller.
Only accessories marketed by CRISTEC may be connected with these chargers.
The following accessories are available for the CPS3 range:
Remote On/Off charger control : reference A/M-CPS3
A 5-metre cable + On/Off switch; connect to K8 connector (see drawing)
Remote Boost control: reference BAD-CPS3
A 5-metre cable + Boost On/Off switch; connect to K11 (see drawing)
Temperature probe: reference STP-CPS3
Compensates the charging voltage according to temperature
12V Charger: -18mV/°C
24V Charger: -36mV/°C
48V Charger: -72mv/°C
A 5-metre cable + probe; connect to K2 (see drawing)
Digital display unit : reference SEEL009104
Displays the state of the charger (ON/OFF), the current of the charger, the voltage on the output.
A 10-metre cable + display unit; connect to K3.
K10 connector
Enables to connect an analogue ammeter and voltmeter to view the current of the charger, the output voltage
of +BAT1 and +SP.
These options must be connected to K10 with a specific cable, ref. DEP-V-A-CPS3 (for further information,
please contact CRISTEC).
