Victron Energy - 12V - Orion XS 12/12-50A DC-DC Smart Battery Charger - EMC Improved Version

Victron Orion XS 12/12-50A: Advanced DC-DC Charging with EMC Optimisation

Precision Power Management for Dual-Battery Systems

The Victron Orion XS 12/12-50A DC-DC battery charger delivers intelligent, high-efficiency charging for auxiliary batteries in vehicles and vessels. Engineered with enhanced electromagnetic compatibility (EMC), this model significantly reduces interference with sensitive onboard electronics such as VHF radios, making it a superior choice for marine and communications-critical installations. Its adaptive charging algorithm and wide-range current control ensure your secondary battery receives an optimal charge profile, extending service life and maintaining reliable performance across diverse conditions.

With a peak efficiency of 98.5%, the Orion XS minimises energy loss and operates without a cooling fan. Instead, it uses an advanced aluminium circuit board for passive thermal management, resulting in silent, maintenance-free operation. This compact, IP65-rated unit is built to withstand dust, water spray, and the vibration typical of mobile and off-grid environments.

Key Features

• 98.5% peak efficiency with fanless aluminium PCB cooling for silent, reliable operation
• EMC-enhanced design reduces interference with VHF radios and other sensitive electronics
• Fully adjustable 1–50 A input/output current in 0.1 A steps via VictronConnect for precise control
• Adaptive 4-stage charging for lead-acid batteries plus a fixed-voltage power supply mode
• Bluetooth Smart and VE.Direct for wireless monitoring, configuration, and system integration
• IP65-rated enclosure with protective terminal cover for harsh marine and automotive environments
• Compact dimensions (137.3 x 123.1 x 40 mm) and lightweight (0.33 kg) for flexible installation

Engineered for Demanding Environments

The Orion XS 12/12-50A is purpose-built for applications where reliability and space are at a premium. Its sealed IP65 housing protects against dust ingress and low-pressure water jets, while the recessed screw terminals and included terminal cover prevent accidental shorts and debris accumulation. The unit’s wide operating temperature range (-20 °C to +60 °C) and full 700 W continuous output up to 40 °C ambient ensure consistent charging even in engine bays and unventilated compartments. For installations with restricted airflow, the charger intelligently derates output to prevent overheating, safeguarding both the unit and your batteries.

Smart Charging, Simplified Control

Using the free VictronConnect app, you can monitor real-time charging data, adjust input and output current limits, and configure battery parameters from your smartphone or tablet. The integrated VE.Direct port provides a wired connection option for GX devices or a PC, enabling advanced system monitoring and data logging. The remote on/off terminals allow integration with external switches or battery management systems, giving you flexible control over charging cycles.

Installation Considerations

For optimal performance, we recommend 70 A fusing on the starter battery side and 60 A on the auxiliary battery side. Cable sizing depends on run length: 6 B&S (approx. 13.3 mm²) is suitable for standard installations, while 4 B&S (approx. 21.2 mm²) is advised for extended cable runs to minimise voltage drop. The charger accepts cable cross-sections up to 25 mm² (AWG4) via its robust screw terminals. Always refer to the installation manual for detailed mounting and ventilation guidelines to ensure full rated output.

Applications

• Marine vessels with VHF and navigation electronics
• Caravans, campervans, and motorhomes with smart alternators
• 4WD and overland vehicles with dual-battery systems
• Off-grid cabins and tiny homes requiring compact DC-DC conversion
• Industrial and mobile equipment with 12 V auxiliary power needs

Why the Orion XS Stands Out

Unlike generic DC-DC chargers, the Orion XS combines adaptive charging intelligence with robust EMC performance, addressing two common pain points in mobile power systems: battery longevity and electromagnetic interference. Its fully adjustable current limits allow you to protect small alternators or prioritise other loads, while the silent, fanless design eliminates noise in living spaces. The result is a charger that integrates seamlessly into professional and recreational setups alike, delivering dependable power without compromise.

Upgrade Your Mobile Power System

Equip your vehicle or vessel with the Victron Orion XS 12/12-50A and experience precise, efficient, and interference-free charging. Whether you're navigating coastal waters or exploring remote tracks, this charger provides the intelligent power management your auxiliary battery demands.
