Typical wiring block diagram of the Battery Charger with 3 batteries bank:
AC Source:
(90-265Vac,
50Hz/60Hz)
Battery Bank_1, _2, _3:
• The charger can charge four different types of batteries (GEL, AGM, Flooded and Lithium)
and each battery bank can have its own bulk, absorption and float current setting.
• By setting the battery type to ‘Program’, the charger will act as a power supply and can
provide power to Bank_1 only. Bank_2 and Bank_3 are disabled.
Branch Breaker:
For AC Input hardwire charging systems, it is required to use a 15A branch breaker to connect
between the AC source and the charger AC input.
AC Source:
The charger accepts full universal input voltage (90-265Vac, 47-63Hz).
Digital Display Port:
Use for external display
The interface port is used for connecting an optional external display. The external display has
identical functions to the built-in display.
Use for PC interface
• A KISAE Abso Charger PC Interface Kit (sold separately) is available and is used to connect
between the port and the PC. This can be used to monitor and make changes to the charger
settings.
• Full details of the KISAE Abso Charger PC Interface Kit, it can be found on the KISAE website

the battery.
• A KISAE Abso Charger Temperature Sensor (sold separately) is available and is used to
connect to one of the battery terminals. It measures the battery temperature and will make
small adjustments to the battery charging voltage for better battery charging performance.
• If the temperature sensor is not used, you can also manually set the charger to Low, Normal,
or High to reflect the environmental temperature for better charging effect. See more details
on Understanding the Battery Temperature Function in Section 5.
Digital Display:
• ‘Mode’ only turns on during the setting of charging stage (Mode 2 – 2 stage: Bulk and
Absorption mode only, or Mode 3 – 3-stage: Bulk, Absorption and Float charging).
• ‘Temp’ only turns on during the setting of battery temperature.

Note 1: Equalization setting can only be used on flooded battery type selection only. See more
details on Procedure to Equalize the Flooded Battery.
Note 2: Charger will terminate charging when char ging current drop to below the set charger
termination value.
Note 3: Charger is acting as a power supply with selected constant output voltage and preset
maximum output current. With this setting, only Bank 1 can be used, Bank 2 and 2 is
Battery Bank Size Recommendation:
The battery charging current rating is based on the battery size. Each battery bank should meet
the minimum Ah rating as shown. If a smaller size battery bank is used, set the current rating to
lower value to match with the battery bank size. Normally, the minimum battery bank capacity is
based on twice the charger current rating.
