Load Curve - Cristec CPS3 24V/150A-TRI Manuel D'utilisation

- the type of battery (contact the battery manufacturer if necessary)
- the intended usage
- the cross-section and length of the output cables
- whether or not the boost function is required
For special batteries, call in a professional installer, who will make the specific settings in accordance with
the accumulator manufacturer's specifications and according to the specifics of the installation.
CRISTEC disclaims any liability in case of damage to batteries or ineffective recharging.

3.3.4. Load curve

BOOST in ON position
With this setting the CPS3 charger delivers a 3-state load curve IUoU: BOOST, Absorption, Floating.

U Boost: BOOST voltage (see table above)
U Floating: Floating voltage (see table above: voltage with no BOOST)
T Boost: BOOST maximum duration (see table above)
Boost phase: starts up automatically when the charger is turned on if the battery is flat. The current is
then at maximum output.
Absorption phase: begins when the voltage has reached the maximum BOOST level. The current level
starts falling.
These two phases combined last a maximum of T
15% of rated current, the floating phase automatically kicks in. Duration and current intensity depend on
how charged the battery is.
Floating phase: starts after T
The voltage switches to the Floating value and the rated current continues to drop.
