Typical wiring block diagram of the Battery Charger with 3 batteries bank:
Battery Bank 1, 2 and 3 setting:
There are two main settings required on the charger for battery charging:
Battery Bank 1 Setting (CH 1):
• Battery type (GEL, AGM, Flooded, Lithium)
• Maximum charging current (‘h-current’ in A)
• Absorption to float stage current (‘L-current’ in A - GEL, AGM, Flooded battery type only)
• Number of charging stages (Mode 2 – Bulk and Absorption stage only, Mode 3 – Bulk,
Absorption and Float stage)
• Battery temperature (Low- ‘Lo’, Normal – ‘nor’, High – ‘hi’)
• Charge voltage (14.2, 14.3, 14.4 in V - Lithium battery type only)
• Charge voltage for Lithium Battery type setting
AC1220, AC1240, AC1260: 13.9, 14.0, 14.1, 14.2, 14.3, 14.4 V
AC2430: 27.8, 28.0, 28.2, 28.4, 28.6, 28.8 V
• Charge termination current (‘L-current’ in A - Lithium battery type only)
Battery Bank 2 and 3 Setting (CH 2 and 3)
:
• Battery type (GEL, AGM, Flooded only, not applicable for Lithium battery)
• Maximum charging current (‘h-current’ in A)
• Absorption to float stage current (‘L-current in A’ – GEL, AGM, Flooded battery type only)
The charger can also be set to Power Supply Mode (Program setting on CH 1). With this setting,
the charger will only provide constant voltage and current to Battery Bank 1 (CH 1) only, Battery
Bank 2 and 3 (CH 2 & 3) are disabled. Even with battery banks are connected to the two banks,
no DC voltage or current will be supplied to these two banks. The charger will act as a constant
voltage power supply with user selected supply voltage and maximum current.
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).
