Usage Note: Typical AC outlets are 1540VA, 14 amp service. To run the higher power units you will need higher power service than is typically available in a wall plug. Please consult competent technical authorities to determine the total load on the circuit you intend to supply the power with, including other things plugged into the same circuit.

Maintenance mode: After the 12V battery is full the charger goes into a maintanence mode. In maintenance mode the battery is safely floated at 13.56 volts to maintain the battery and replace charge lost due to leakage or self discharge. In addition, if the battery has not received a bulk charge during a seven-day period, the charge controller will switch the APS Power Supply into a pre-programmed equalization stage to top off the batteries, dissolving any sulfate layer on the battery’s plates and avoiding stratification of flooded batteries.

Audio Application Note: Operating high power audio systems from the battery while it is on charge can cause the charger to change charge stages at random, which you might be able to hear. If you are running equipment from the battery while the charger is attached you can remove the jumper plug from the charger, which will revert it to a 13.6 volt power supply to give you better sound. Just plug it back in to make it a multistage charger.

To perform this function remotely put a toggle switch in the jumper as follows
