Victron Energy Orion-Tr Smart 24/24-12A (280W) Isolated DC-DC Charger

Technical Specifications User manual 

The Victron Energy Orion-Tr Smart 24/24-12A is an isolated DC-DC battery charger designed to charge a 24V auxiliary battery from a 24V DC power source. With built-in Bluetooth, configurable charging profiles and an adaptive three-stage charging algorithm, it provides controlled charging for RVs, camper vans, boats and other mobile electrical systems.

FEATURES

• 12A charging current: Delivers up to 280W of continuous output power at 40°C.

• Built-in Bluetooth: Monitor, configure and update the charger using the VictronConnect app.

• Adaptive three-stage charging: Bulk, absorption and float charging for lead-acid batteries, with configurable settings for lithium batteries.

• Galvanic isolation: 200V DC isolation between input, output and case.

• Smart alternator compatibility: Engine-running detection helps prevent starter-battery discharge when the engine is off.

• Flexible configuration: Adjustable output voltage, remote on/off connection and parallel operation with additional units.

• Protection: Short-circuit and high-temperature protection, with output current reduction at elevated temperatures.

• IP43 protection: Applies when installed with the screw terminals facing downward.
