This series of 3 Stage chargers have 3 specific settings for Wet, Cal-Cal, AGM & GEL type batter y to ensure fast, complete and safe charging of your battery as required by the manufacturers.
Soft Start Bulk Charge an pre-bulk charge for drained out battery.
The charger gives 50% of full constant current charge when it detects the battery is over depleted at less than 18V terminal voltage. When battery voltage rises to 22V the charger will resume the normal constant full current Bulk, constant voltage Absorption and Float charge stages.
In the Power Supply mode, the charger provides a constant voltage dc power to the external load connected to the battery and at the same time without over charging the battery. This is ideal for caravan and other battery backup applications. The Power Supply Mode output voltage is the selected Float Voltage.
The optional temperature sensor adjusts the charging voltages with the changes in ambient temperatures of the battery. This effectively prevents over and under charging the battery in hot summer days to cold wintry nights.
Only the 5Amp SBC-2205 model has convection cooling and one charging bank, others have thermal control fan cooling (zero to full speed) and dual charging banks.
The Over Voltage protection, in the case of component failure causing uncontrolled high voltage at the output, the charger will limit the
voltage less than 2V to prevent damage to the battery and connected load.
