occurs earlier):
a) When the 4 Hr / 8 Hr Absorption Stage Timer (Selected by DIP Switches "S3" and
"S4"- See Section 7.5, Table 7.3) runs out OR,
b) When the charging current tapers down to 10% of the rated "Bulk Current Capac-
ity" of the charger;
• 5A +/- 0.5A for SEC-1250UL
• 3A +/- 0.5A for SEC-2425UL
4.3.2.3.3 Thresholds of Charger Currents for Change over Between Absorption and
Float Stages: The thresholds of charger current for change over between the Absorption
Stage (Displayed as "Absorption"/"U0 Phase" in optional Remote Control 900-RC) and
Float Stage (Displayed as "Float"/"U Phase" in optional Remote Control 900-RC) are
shown below:
Change Over
From Absorption Stage (Level 2) to Float Stage
From Float Stage to Absorption Stage (Level 1)
4.3.2.3.4 Charging Characteristics during Absorption Stage
• Absorption Stage Levels 1 and 2 (Displayed as "Absorption"/"U0 Phase" in op-
tional Remote Control 900-RC) feed additional 35% to 55% of the capacity that
adds to the total charged capacity of around 115% to take care of around 15%
loss due to charger efficiency
• There will be moderate gassing during this Absorption Stage
• Orange LED marked "Absorption"/"U0 Phase" on the optional Remote Control
Model No.900-RC will be lighted
4.3.2.4 Thresholds of Charger Currents for Change over Between Absorption and Float
Stages: The thresholds of charger current for change over between the Absorption
Stage (Displayed as "Absorption"/"U0 Phase" in optional Remote Control 900-RC) and
Float Stage (Displayed as "Float"/"U Phase" in optional Remote Control 900-RC) are
shown below:
Change Over
From Absorption Stage (Level 2) to Float Stage
From Float Stage to Absorption Stage (Level 1)
4.3.3 Stage 3 - Float Stage
4.3.3.1 During this stage, the charger outputs a constant Float Voltage of (i) 13.5V for
SEC-1250UL or, (ii) 27.0V for SEC- 2425UL. This helps in maintaining full capacity of the bat-
tery and also provides replacement charge to overcome self discharge of the battery. The
battery can remain connected in this stage indefinitely without the risk of discharging.
