1.5 Autom atic battery voltage recognition
The controller w ill automatically adjust itself to a 12V or a 24V system.
1.6 Three step charging
The controller is configured for a three step charging process: Bulk – Absorption - Float.
1.6.1. Bulk stage
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
1.6.2. Absorption stage
When the battery voltage reaches the absorption voltage setting, the controller sw itches to
constant voltage mode.
When only shallow discharges occur the absorption time is kept short in order to prevent
overcharging of the battery. After a deep discharge the absorption time is automatically
increased to make sure that the battery is completely recharged.
Additionally, the absorption period is also ended w hen the charge current decreases to less
than 1 A.
1.6.3. Float stage
During this stage, float voltage is applied to the battery to maintain it in a fully charged state.
When battery voltage drops below 13,2 Volt during at least 1 minute a new charge cycle will
be triggered.
