Orion-Tr Isolated DC-DC Charger Remote Control Cable

This cable is designed for Victron Energy Orion-Tr isolated DC-DC chargers. It allows remote modification of the on/off signal reference point. By default, this signal is referenced to the primary battery (e.g., the starter battery). With this cable, the signal can be referenced to the secondary battery (e.g., a lithium battery with BMS), which is essential for certain battery system configurations.

This cable is specifically designed for use with the Orion-Tr range of Victron Energy isolated DC-DC chargers. It is not intended for non-isolated chargers or other Victron Energy product ranges.

You need this when the Battery Management System (BMS) of your secondary battery (often a lithium battery) is responsible for activating or deactivating the charger. By referencing the signal to the secondary battery, the BMS can directly control the charger's operation safely and appropriately, preventing potential issues or malfunctions.

The Orion-Tr Isolated DC-DC Charger remote control cable can handle a maximum input voltage of 35 V.

The maximum output voltage this cable can support is 70 V.

A minimum input voltage of approximately 4 V is required for the 'pull down' function of this cable.

The maximum 'pull down' current is approximately 30 mA. The cable is also protected against short circuits.

Yes, the Orion-Tr Isolated DC-DC Charger remote control cable is protected against short circuits.

No, this cable is not required for all Orion-Tr isolated DC-DC chargers. It is specifically intended for applications where the remote on/off signal must be referenced to the secondary battery rather than the primary battery, which is the default behavior of these chargers.

No, this cable is specifically designed for insulated Orion-Tr DC-DC chargers. It is not compatible with uninsulated Orion-Tr models, as their signal reference architecture for remote control differs.

The cable is designed for applications where the remote on/off signal is referenced to the secondary battery. While the typical example is a lithium battery with BMS, the key point is that your installation requires the control signal to be managed by the secondary battery rather than the primary one. Check the documentation of your secondary battery and system to confirm whether this configuration is necessary.

The cable is designed to interface with the Orion-Tr Isolated charger's remote on/off circuit. It establishes the necessary connection for the control signal to be referenced to the secondary battery. The precise connection details are typically found in the Orion-Tr Isolated charger installation manual.

Unlike a standard connection cable that transmits power or simple signals, this cable is a targeted solution for managing the signal reference of the control circuit. It ensures that the electrical reference point of the on/off signal is correctly aligned with the secondary battery, which is crucial for the reliability of complex installations, particularly with advanced batteries.

No. The Orion-Tr Isolated DC-DC Charger remote control cable is a separate accessory. It is not included by default with the Orion-Tr Isolated chargers.

This cable is particularly useful in nautical applications where an advanced service battery (such as a lithium battery) is managed by a Battery Management System (BMS) that must control the activation and deactivation of the DC-DC charger. This ensures secure and compliant integration of the boat's power system components.

Yes, since its maximum input voltage is 35 V and maximum output voltage is 70 V, this cable is compatible with boat electrical systems operating on 12V or 24V, which are the common voltages for Orion-Tr chargers.

In the context of electronic circuits, a 'pull down' refers to a mechanism that lowers a signal’s voltage to a low level (typically near 0V or ground) when the signal is not actively driven high. For this cable, this indicates the ability to pull the remote control signal down to a low level to turn off the charger, with a minimum required input voltage of 4V.

No, this cable is specifically designed for Victron Energy Orion-Tr isolated DC-DC chargers. It is not guaranteed to work correctly or be compatible with chargers from other brands, as specifications and remote control interfaces can vary significantly.

During installation, it is crucial to follow the specific instructions provided in the Orion-Tr Isolated DC-DC charger manual and ensure that connections are correct. Special attention must be paid to signal referencing to avoid potential or operational issues. It is recommended to consult a professional if you are unsure about the installation.

The main advantage is to ensure correct integration and control of the Orion-Tr isolated DC-DC charger in complex systems, particularly those using lithium batteries with a BMS. It allows the secondary battery's BMS to directly manage the start/stop signal of the charger, ensuring safe, efficient operation that complies with battery management system requirements.
