Victron Energy Orion XS 12/12-50A DC-DC Charger

High-Output In-Vehicle Alternator Charging, Next-Generation Thermal Efficiency, and Seamless GX Data Integration: The commercial-grade Victron Energy Orion XS 12/12-50A DC-DC Battery Charger (ORI121250140) represents the pinnacle of mobile power generation, supplying up to 50 Amps of fully adjustable charging current to 12V auxiliary banks directly from a vehicle alternator. Operating at an astonishing 98.5% efficiency standard utilizing cutting-edge aluminum PCB technology, this compact, fanless IP65-rated component runs exceptionally cool—completely removing the need for oversized external heatsinks. Built with advanced smart alternator engine-running detection parameters, it isolates the starting battery and prevents the heavy current draws of modern storage banks from overloading your engine electronics, functioning as an indispensable energy harvester within modern lithium power systems. Outfitted with a native VE.Direct communication port for unified data logging on Cerbo GX modules and integrated Bluetooth for local smartphone diagnostics, it delivers the micro-precision voltage regulation required to maximize performance and protect the internal cells of premium LiFePO4 lithium batteries. It is a crucial spatial utility for completing high-performance mobile grids, allowing users to safely stack and parallel multiple units to feed high-capacity configurations of 12V lithium batteries.

Adjustable charging current
The charge current is adjustable with a minimum stepsize of 0.1 A. via VictronConnect.

Smart alternator compatibility
An integrated mechanism detects whether the engine is running (engine shutdown detection), which only activates the charger when the alternator supplies power. This ensures that the charger only draws power when the alternator is supplying power, i.e. when the engine is running.

Adaptive 4-stage charge algorithm
For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged.
The Orion XS includes fully programmable charging algorithms and eight pre programmed battery settings.

Low temperature shutdown and input undervoltage protection
To prevent damage of lithium batteries the charger will turn off automatically at low temperatures. It will also shut down when the input voltage drops below a configurable lockout value and restart when the input voltage rises above the restart value, this to protect the input source ie. starter battery from deep discharge.

Remote on/off
The Orion XS can be switched on and off remotely via the remote on/off connector or the VictronConnect App. Typical applications include wiring a switch or Battery Management System (BMS).

Comprehensive electronic protection
The protections includes overload, short circuit and excessive temperatures. The charger is protected against over-temperature by reducing the output power when the maximum product temperature is reached.

Can be paralleled to increase output current
An unlimited number of units can be connected in parallel.

Bluetooth Smart enabled
Built-in Bluetooth Smart: The wireless solution to change settings, monitor activities and update the Orion XS software using Apple and Android smartphones, tablets or other devices. Various parameters can be adjusted with the VictronConnect App.
Instant Readout: The VictronConnect App can display key data, including warnings and alarms, on the Device list page without the need to connect to the product.
VE.Smart Networking: Use VE.Smart Networking to receive Vsense, Tsense and Isense data over the wireless network for your Orion XS DC-DC battery charger, for example, from a BMV, a SmartShunt, or a Smart Battery Sense. The charger uses the available information from the battery to optimize the charging parameters. This improves charging efficiency and extends battery life.

VE.Direct port and DVCC
For a wired connection to a GX device such as the Cerbo GX or Ekrano GX, PC or other devices. Enables advanced monitoring, control and diagnostics from anywhere (requires a GX device connected to the internet and VRM Portal) or locally via the Remote Console, as well as DVCC (Vsense, Tsense, Isense), System wide charge current limit and BMS control.

IP65 protection
The Orion XS complies with ingress protection rating IP65. This means the product is dust-tight and protected against heavy rain.
