Victron Energy Orion-TR Smart DC-DC 24/24-17 400W Isolated Charger and Power Supply

Orion-TR Smart Isolated DC-DC Converter - 24 VDC to 24 VDC - 400W - 17AMP

The Orion-Tr Smart DC-DC charger is a professional DC-to-DC adaptive 3-stage charger with built-in Bluetooth.

Bluetooth Smart Enabled:

• Any Bluetooth-enabled smartphone, tablet, or other device can be used to monitor, change settings, and update the charger when new software features become available.


• 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.

Fully Programmable:

• Battery charge algorithm (configurable) or fixed output. Smart alternator compatibility: engine running detection mechanism.


• Adaptive 3-Stage Charge Algorithm: Bulk Absorption Float:


• For lead-acid batteries, it is important that during shallow discharges the absorption time is kept short 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.


• For lithium batteries, the absorption time is fixed (the default is 2 hours).


• Alternatively, a fixed output voltage can be chosen.

Suitable for Use in Vehicles with a Smart Alternator (Euro 5 and Euro 6 Engines):

• The built-in engine shutdown detection will stop the converter when the engine is not running. This prevents the unwanted discharge of the starter battery (see manual for details).

Remote On/Off:

• A remote on/off switch or relay contact can be connected to a two-pole connector. Alternatively, the H terminal (right) of the two-pole connector can be switched to battery plus, or the L terminal (left) of the two-pole connector can be switched to battery minus (or the chassis of a vehicle, for example).

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current:

• An unlimited number of units can be connected in parallel.

High Temperature Protected:

• The output current will reduce at high ambient temperatures.

IP43 Protection:

• When installed with the screw terminals oriented downward.

Screw Terminals:

• No special tools are needed for installation.

The Victron Energy Orion-TR Smart DC-DC charger is a versatile and efficient power management solution designed for professional use in various vehicle and marine applications. This 24 VDC to 24 VDC converter delivers up to 400 watts of power with a continuous output current of 17 amps, ensuring reliable performance even in demanding environments. Its compact design and screw terminal connections facilitate straightforward installation without the need for specialized tools, making it suitable for a wide range of setups. The unit features galvanic isolation of 200 VDC between input, output, and case, enhancing safety and reducing electrical noise.
The Orion-TR's advanced adaptive three-stage charging algorithm includes bulk, absorption, and float stages, optimizing battery health for both lead-acid and lithium batteries. For lead-acid batteries, the absorption time adjusts automatically based on discharge depth, preventing overcharging during shallow discharges and ensuring full recharge after deep discharges. Lithium battery charging is fixed at a default two hours absorption time, providing consistent and safe charging parameters. Additionally, the charger can be configured for fixed output voltage operation if desired.
A key feature of the Orion-TR is its Bluetooth connectivity, allowing users to monitor and modify settings via the VictronConnect app on any Bluetooth-enabled smartphone or tablet. This remote management capability includes real-time data display, warnings, and alarms, providing comprehensive oversight without physical access to the unit. The charger also supports remote on/off control through a dedicated switch or relay contact, enabling integration into automated systems.
Designed with vehicle compatibility in mind, the Orion-TR detects engine shutdowns, especially in vehicles with Euro 5 and Euro 6 engines equipped with smart alternators, to prevent unwanted discharge of the starter battery. The unit is short circuit proof and can be paralleled with multiple units to increase overall output current, making it scalable for larger power requirements. Its high temperature protection reduces output current at elevated temperatures, safeguarding the device during operation in hot environments. The IP43 protection rating ensures durability when installed with screw terminals downward, and the device complies with safety standards including EN 60950 and automotive regulations such as ECE R10-5.
Overall, the Victron Energy Orion-TR Smart DC-DC converter combines intelligent charging, safety features, and remote management capabilities, making it an ideal choice for maintaining reliable power in mobile and off-grid systems.
