The Victron Orion-Tr isolated series breaks this connection, providing a 'floating' output that is electrically independent. This is especially important in vehicles and boats where multiple charging sources and varying ground potentials can cause erratic behaviour in connected devices.\u003c\/p\u003e\n\u003cp\u003eAdditionally, the adjustable output voltage allows this converter to be used as a \u003cstrong\u003econstant voltage power supply\u003c\/strong\u003e for equipment that requires a specific voltage, such as LED lighting systems or certain telecommunications gear. Note: This unit is a DC-DC converter, not a multi-stage battery charger.
