Victron Energy Orion-Tr 12/12-18A Isolated DC-DC Charger (Model: ORI121222120)

Safe, Efficient, and Isolated Charging for 12V Systems

The Victron Orion-Tr 12/12-18A Isolated DC-DC Charger is a high-efficiency power management solution for safely charging and powering 12V systems. Designed with galvanic isolation and intelligent electronics, this converter ensures stable 12V output from a 12V input source—ideal for dual battery systems in automotive, marine, and off-grid applications.

Key Features

• Isolated DC-DC Charger
  Converts 12V DC input to a stable 12V DC output with full galvanic isolation—protecting sensitive electronics from interference and grounding issues.

• 18A Output Current
  Delivers reliable charging and power distribution to auxiliary batteries or 12V devices.

• Wide Input Voltage Range
  Operates from 11–16V, making it ideal for varying vehicle and solar battery voltages.

• High Efficiency (up to 93%)
  Reduces energy loss and heat generation, enhancing long-term system reliability.

• Compact, Durable Build
  Rugged construction with passive cooling—perfect for tight installations in vehicles, boats, and mobile power systems.

• Electronic Protection Features
  Includes safeguards against overcurrent, short circuit, overheating, and reverse polarity for worry-free operation.

Technology Overview

The Orion-Tr charger uses Victron’s advanced DC-DC conversion platform to ensure consistent voltage regulation and energy efficiency. The galvanic isolation feature prevents potential electrical ground loops and protects connected components—especially valuable in systems with separate charge sources (e.g., alternator + solar).

Installation & Compatibility

Installation is simple with clearly labeled screw terminals. It can be used:

• In dual-battery vehicle systems (starter + auxiliary battery)

• As a secondary charger from alternators or solar controllers

• With AGM, GEL, Lithium, or Flooded Lead-Acid batteries

Compatible with battery management systems and suitable for smart alternators (with external ignition source control).

Applications

• RV and camper vans with dual battery banks

• Boats and marine systems requiring isolated 12V circuits

• Off-grid solar setups

• Overland vehicles and utility fleets

• Emergency and backup 12V systems
