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.

PowerSafe OPzS batteries feature an increased capacity exceeding the DIN standard. Additionally, the die cast tubular plate design with low antimony offers excellent cycling capabilities and a proven long life under float conditions. The pasted negative flat plate design provides the perfect balance for maximum performance.

The MVF consists of a Medium Voltage parallel SPD and stand-alone, three phase fuse box. The MVF is designed for Oil and Gas, Water/ Wastewater, Chemical, Large Industrial and Heavy-Duty Applications at Service Entrance, Distribution locations as well as Individual Equipment. The Three Phase Fuse Box component of the MVF is REQUIRED to be installed on the line side of, and in-line with, the Medium Voltage SPD component as dedicated overcurrent protection and to safely disconnect the SPD from the electrical system in the event of an SPD failure.
