The A48/A48B is a completely automatic, solid state, constant voltage Battery Charger built to carry continuous and intermittent loads up to 80% of its maximum rated output capacity. It automatically senses the battery and load conditions and delivers the necessary amount of charge.
The A48/A48B Battery Chargers are equipped with a built-in charge divider circuit to isolate and charge two separate sets of batteries of the same nominal DC Voltage either independently or simultaneously. The operation is completely automatic-a voltage sensing relay is provided to automatically transfer the output of the Battery Charger to the high rate charge mode, after engine cranking or following a power failure. This will bring the batteries to a fully charged state within 24 hours. Once the batteries are fully charged, the relay will automatically transfer the charge rate back to the Float rate to prevent overcharging and protect the batteries.
