3.3.5. Load curve

BOOST in ON position
With this setting the YPOWER charger delivers a 5-state load curve IUoU + automatic weekly recycling
(switch F) + return to automatic BOOST : BOOST, ABSORPTION, FLOATING + REFRESH, REBOOST.
V BOOST : BOOST voltage (see table above)
V FLOAT : FLOATING voltage (see table above : voltage with no BOOST)
T BOOST : BOOST maximum duration (see table above – paragraph 3.3.2)
T ABS : ABSORPTION maximum duration (see table above – paragraph 3.3.2 )
BOOST (I) phase :
Starts up automatically when the charger is turned on if the battery is flat. The current is then at maximum
output.
ABSORPTION (U1) phase :
Begins when the voltage has reached the maximum charge voltage level and the current falls under 90% of
the nominal current. Minimum duration is 6 minutes.
These two phases combined last a maximum of T
of rated current, the floating phase automatically kicks in. Duration and current intensity depend on how
charged the battery is.
FLOATING (U2) phase :
Starts after TBOOST or if output current has reached 20% of the charger's rated current. The voltage
switches to the FLOATING value and the rated current continues to drop. Minimum duration is 6 minutes.
(depending on setting). If the current falls below 20%
