Test the Charger Connection: 

  Switch AC branch breaker switch to ON. 

  The display will turn on. Pressing the ‘

INFO

’ key will toggle the display to show the factory 

default setting. The charger is now ready to use.   
 

5. UNIT OPERATION 

Understanding the Charging Mechanism 

  The charger is a three bank battery charger that is capable of charging a maximum of three 

battery banks. 

  The charger is designed to have Bank 1 charge the main battery bank. Always use Bank 1 

first when connected to a single battery bank.  

  At start, if the charger senses Battery Bank 2 and 3 had battery connected and the battery 

voltage is greater than 11V on 12V model (

AC1220, AC1240, AC1260

)

 or greater than 22V 

on 24V model (

AC2430

)

, the charger will then concentrate on fully charging Battery Bank 1 

first until it reaches float stage. It will then switch to charge Battery Bank 2 and 3. 

Or  

  If the charger senses either Battery Bank 2 or 3 had battery connected and the battery voltage 

is below 11V on 12V model (

AC1220, AC1240, AC1260

)

 or below 22V on 24V model 

(

AC2430

)

, it will cycle to charge Bank 1 for 15 minutes then Bank 2 and 3 together for 15 

minutes. When the charger senses both Bank 2 and 3 reached 13V on 12V model (

AC1220, 

AC1240, AC1260

)

 or 26V on 24V model (

AC2430

)

, it will then concentrate on charging Bank 

1 until it reaches the float stage. After, it will then concentrate on recharging Bank 2 and 3 to 
float stage. 

  Once all three banks have reached the float stage, the charger will adjust the charging voltage 

to the preset float voltage and all three banks will be connected in parallel for float stage 
charging. During the float stage charging stage, each battery bank is separate by an internal 
separation diode.  

  In float stage, see the below chart for the maximum allowable current draw:

AC 2430 

Maximum Float Current 

40A 40A 20A 20A 

For charging 

GEL, AGM

 and 

Flooded

 batteries: 

  The charger can be set to ‘

Mode 2

’, 2 stage charging (Bulk and Absorption stage charging 

only- no float stage) or ‘

Mode 3

’, 3 stage charging – (Bulk, Absorption and Float stage 

charging). 

  Each battery bank can have its own maximum charging current and absorption-to-float 

mode current settings. 

For charging Lithium batteries: 

This can only be set at Bank 1, it has its own charging voltage and current setting. It also 
requires the user to set the charger termination current. The charging process will terminate 
when the charging current drops to the set termination current. 

For using charger as Power Supply (Program setting): 

The charger can be used as a constant voltage power supply that will deliver the preset output 
voltage with the maximum current setting. With this setting, only Bank 1 can be used and the 
other banks are disabled. 

 

Understanding the Digital Display and the Function Keys during Normal Operation: 

During normal operation, the display shows the related channel’s battery voltage, charging 
current and charging stage (‘

bul

’ – Bulk stage, ‘

Abs

’ – Absorption stage, ‘

Flo

’ – Float stage) 

alternatively. When the ‘

INFO

’ key is pressed, it displays other channel’s battery voltage only.  

When all channels reach float stage, the display will show ‘

Ful

’ indicating all the batteries 

connected are fully charged. 
During equalization operation on flooded battery, the numerical section on the display will show 
a flashing ‘

eq

’ indicating the equalization process is in progress and it will 

not

 show the battery 

voltage or the charging current.
