Victron Orion-Tr Smart 24/12-20a (240w) Isolated Dc-Dc Charger

Orion-TR Smart 24/12-20A (240W) Isolated DC-DC Charger

The Orion-Tr Smart isolated DC-DC charger serves as a DC-DC battery charger or a power supply (also designed for use as a constant voltage source), offering a wide input and output voltage range. This is especially significant in the case of vehicles with a Euro 5 or Euro 6 smart alternator, which often supplies too low charging voltage even when the engine is running or when extended cable lengths, as is often the case in boats and RVs, lead to voltage drops. In such scenarios, precise and controlled charging is imperative to fully charge the service battery while protecting the starter/input battery from discharge.

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. Orion-Tr Smart 12/12-30 Orion-Tr Smart 12/12-30
  • 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 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.
