The 5300 Series brings output Amperages to 50-Amp shore services that have never been seen before. The 5375 is a 50-Amp Power Center with a three current stage 75-Amp Converter Charger. Manufactured with active power factor correction that allows the converter sections to operate on 120VAC 15-Amp branch circuits, leaving plenty of power for running other 120VAC devices. The unit is built with a durable steel enclosure and has a 15-position fuse block with blown fuse indicators. This product can be upgraded to TempAssure™ technology by installing the Parallax 4400TAU module to maximize battery charging.
