Thermal Derating - Cristec HPOWER 12V/90A Manuel Utilisateur

REFRESH phase :
It is an automatic weekly cycle (Inhibited or not by means of switch F) in order to optimize the battery life duration.
It will occur only after a complete recharge cycle (BOOST, ABSORPTION and FLOATING).The charger will generate
automatically a safe timed voltage step every 7 days whatever the position of BOOST switch.
Phase REBOOST :
Automatic phase consisting in coming back to a BOOST voltage if the DC utilizations require it (i.e. after a complete
recharge cycle BOOST, ABSORPTION and FLOATING if a some DC constant consumptions are detected the charger
will restart a new complete charge cycle including a BOOST phase).
This REBOOST phase will be authorized after measuring certain battery voltage during a determined time.
BOOST in OFF position
With this setting, the CDS4 charger produces a single-stage UI type charge curve. It generates a constant voltage,
supplying the current required by the battery(ies). Recharging time depends on the state of the battery, and is longer
than when the BOOST is in the ON position.
