The Victron Orion XS 12/12-50A is a non-isolated buck-boost DC-DC battery charger designed for dual-battery setups in vehicles, marine craft, and off-grid mobile systems. Housed in a compact IP65 enclosure measuring 137.3 x 123.1 x 40 mm and weighing 0.330kg, the unit regulates alternator power to charge auxiliary battery banks safely.
The device provides an input and output current setting range of 1-50 A with a maximum constant short-circuit current of 50 A. Under normal conditions up to 40°C, it delivers continuous output power of 700 W. At elevated temperatures from -20 to +60°C, output power derates at 1.5% per °C above 40°C.
Voltage Windows & Efficiency
The buck-boost architecture accommodates broad voltage fluctuations common with smart alternators:
- Input Voltage Range: 9-17 V.
- Output Voltage Adjust Range: 10-17 V, with an output voltage tolerance of +/- 0.25% and output voltage noise of 10mV rms.
- Efficiency: Maximum efficiency reaches 98.5%.
- Quiescent Drain: No-load current consumption is < 100mA, while standby current consumption drops to < 1.5mA when engine shutdown is detected.
Wiring & Physical Installation
DC cabling connects via heavy-duty screw terminals accommodating a maximum cable cross-section of 4 AWG (21.2mm²). The unit operates up to 2000 m altitude in environments with up to 95% non-condensing humidity.
