Note 1: Equalization setting can only be used on flooded battery type selection only.
See more details on the Procedure to Equalize the Flooded Battery section
Note 2: Charger will terminate charging when charging current drops below the set termination value.
Battery Bank Size Recommendation:
The battery charging current rating is based on the battery size. When charging GEL, AGM and
Flooded batteries, each battery bank should meet the minimum Ah rating as shown. If a smaller
size battery bank is used, set the current rating to a lower value to match with the battery bank
size. Normally, the maximum charger current rating is based on half the battery bank capacity.
Current Setting (A)
Minimum Battery Capacity (Ah)
When charging Lithium battery, consults the Lithium battery manufacturer for maximum
allowable charging current.
Power Supply
The charger can also be set to power supply mode (Program setting). With this setting, the
charger will only provide constant voltage and current to CH 1, while CH 2 & 3 (Bank 2 & 3)
are disabled. No DC voltage or current will be supplied to Ch 2 & 3 even if battery banks are
connected to the two channels. The charger will act as a constant voltage power supply with
user selected supply voltage and maximum current.

Digital Display:
'CH1', 'CH2' and 'CH3' represent Battery Bank 1, 2 and 3
•
respectively. With 'CH1' turned on, the numerical value on
the display shows individual battery information like battery
voltage in 'V' or charging current in 'A'. 'CH 2' and 'CH 3' will
always turn on together, the numerical value on the display
shows the total charging current in 'A'
• ' GEL', 'AGM', 'Flooded', 'Lithium' and 'Program' represent
different battery types setting.
• 'Auto' indicates Silent Mode is activated
• 'Mode' only turns on during the setting of charging stage
Mode 2 - (2 stages: Bulk and Absorption stage)
Mode 3 - (3 stages: Bulk, Absorption and Float stage)
• 'Temp' only turns on when manually setting of battery
temperature.
