Converter Victron Orion-Tr Smart 12/48 8A isolated – ORI124838120

The Victron Orion-Tr Smart 12/48 8A Isolated Victron Converter – ORI124838120 serves as a DC-DC battery charger or as a power supply. The victron orion Smart can only be configured to provide power when the engine is running. In charger mode, the three-stage charging algorithm will extend the life of the battery.

Features of the Victron Orion-Tr Smart 12/48 8A insulated

Bluetooth Smart enabled

• Any smartphone, tablet or other Bluetooth-enabled device can be used to monitor the victron orion tr smart, change settings and update the charger when new software features become available.
• Instant Readout: The VictronConnect app can display the most important data, as well as warnings and alarms, on the device list page without the need to connect to the product.

Fully programmable

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

3-stage adaptive loading algorithm: initial loading – absorption – floating

• In the case of lead-acid batteries, the absorption time should be short if the discharges to be made are light. After a deep discharge, the absorption charging time is automatically increased to ensure a complete recharge of the battery.
• For lithium batteries, the absorption time is fixed: 2 hours.

Victron orion tr: Suitable for use in vehicles with an intelligent alternator (Euro 5 and Euro 6 engines).

• The integrated engine shutdown detection will stop the inverter when the engine is not running. This prevents the starter battery from discharging (see manual for details).

Remote On/Off

• A remote On/Off switch can be connected to a two-phase connector. Alternatively, the H (right) terminal of the two-phase connector can be switched to battery positive, or the L (left) terminal of the two-phase connector can be switched to battery negative (or to the vehicle chassis, for example).

Extensive electronic protection of this orion victron

Over-temperature protection and power reduction in case of high temperature.

• Overload-proof.
• Short-circuit proof.
• Connector overtemperature protection.

Other functions of the victron orion tr smart

• All models are short-circuit proof and can be connected in parallel (unlimited number) to increase the output current.
• Input voltage lock: Turns off if the input voltage drops below the locking value and restarts if the input voltage rises above the value.
  restarting.
• Separation of the starter battery and the auxiliary battery: The victron orion 12/48 8A booster separates the starter battery and the auxiliary battery when the engine is not running.
• High temperature protection: The output current will be reduced when the ambient temperature is high.
• IP43 protection: If installed with the screw terminals facing downwards.
• Screw terminals: No special tools needed for installation

Installation of victron Smart 12/48 8A Isolated booster

Assembly

• It must be installed vertically on a non-flammable surface, with the power supply terminals facing downwards.
• A minimum safety distance of 10 cm must be left around the product for optimal cooling.
• Place it close to the battery, but not directly on top of it, to avoid damage caused by gassing the battery.

Wiring and fuses

• Use flexible multi-stranded copper cables for battery connections.
• Each strand must have a diameter of less than 0.4 mm (0.016 inches) or a cross-section of less than 0.125 mm² (AWG26).
• The maximum working temperature is 90 °C (194 °F).
• For example, a 16 mm² cable must have at least 122 strands (strand class 5 or higher according to VDE 0295, IEC 60228 and BS6360).
• If thicker filaments are used, the contact area will be too small and the resulting high contact resistance will lead to severe overheating which could cause a fire.

Recommended cable type

To properly connect a cable to the input and output screw terminals, flexible and very flexible core wire cables can be used:

• IEC 60228 – Class 2 (stranded conductor), Class 5 (flexible), Class 6 (very flexible)
• UL486A-B – Class B/C (stranded conductor), Class I (flexible), Class K (very flexible)
• Stranded core cables are very stiff, so they are hardly used in practice.
• A torque of 1.6Nm is recommended.

The following table shows the minimum cable dimensions:

Check polarity

• The Victron Orion-Tr Smart 12/48 8A isolated Victron Converter is not protected against reverse polarity of the battery. Possible damage caused by reverse polarity is not covered by warranty. In addition, devices damaged by reverse polarity cannot be repaired.
• Always check the polarity of the battery before connecting or reconnecting the cables to the victron orion tr.
• Do not attempt to connect the battery cables to the victron booster, only if the input and output terminals are safely accessible.
• Be careful not to bend any strands when inserting the wires into the input and output terminals.
• Connect the battery cables to the victron booster first, check the polarity of the battery once more and connect the battery.

The following picture shows the correct way to make the connection:

DC-DC power supply mode configuration

• Disconnect the remote on/off, remove the jumper or unplug the terminal block.
• Connect the input power cables.
• Open the VictronConnect application to configure the product.
• Connect the load. The victron booster is now ready to be used as a power supply.
• Reconnect the remote on/off to activate the product.

Configuration for charger mode

• Disconnect the remote on/off, remove the jumper or unplug the terminal block.
• Connect the input power cables.
• Configure from the VictronConnect application.
• Connect the battery to be charged.
• Switch the remote on/off again to activate the product.
