Victron Autotransformer 120/240V-100A For step up, step down and split phase balancing An Autotransformer can be used for step up, step down and split phase output balancing purposes. While the step up and step down functions are fairly straightforward, split phase output balancing may require some more attention. When operating in inverter mode, the neutral output of the inverter/charger must be connected to the ground to guarantee the proper functioning of a GFCI. In the case of a split-phase supply, the neutral must be grounded. For this purpose, a grounding relay is built into the autotransformer’s enclosure. Features Step-up, Step-down, or Balance your System Ground Relay Included Temperature Protection 13.5 kg / 29.7 lbs. Dimensions:425 x 214 x 110 mm Input Voltage:120/240V Input Breaker Size:100A / 2-Pole Transformer Type: Toroidal Protection Category:IP21
