For boats, RVs, and other mobile setups, the Victron Orion-Tr Smart 12/24-10A (240W) Isolated DC-DC Charger or Power Supply delivers reliable charging for your service battery while keeping your starter battery safe. Its isolation and broad input/output range help maintain voltage when runs are long or Euro 5/6 smart alternators are in play.
-
Isolated DC-DC charging or regulated power supply: ensures your service battery charges reliably without draining the starter battery, even under challenging voltage conditions.
-
Bluetooth Smart enabled: pair with the VictronConnect app to monitor, adjust settings, and update firmware; instant readouts appear in the device list for quick checks.
-
Smart alternator compatibility with engine running detection: engine running detection helps prevent starter battery discharge, making it ideal for vehicles with Euro 5/6 engines.
-
Adaptive 3-stage charging for lead-acid; lithium support: Bulk – Absorption – Float charging; absorption times tuned to prevent overcharging on shallow discharges and ensure full recharge after deep discharges.
-
Lithium charging specifics: for lithium, absorption time is fixed (default 2 hours), or you can choose a fixed output if preferred.
-
Remote On/Off and easy expansion: connect a remote switch or relay, and you can parallel unlimited units to increase output current as your system grows.
-
Rugged, safe design: short-circuit proof, high-temperature protection (output current reduces at high ambient temperatures), IP43 rating with downward-oriented screw terminals, and a non-replaceable input fuse for peace of mind.
-
Simple installation: screw terminals; no special tools required.
-
Flexible operation: functions as either a battery charger or a constant voltage power supply to maintain critical loads.
-
Key electrical specifications: Input 8–17 V; Nominal Output 24.2 V; Output Adjustable Range 20–30 V; Output Noise 2 mV rms; Continuous Output Current (nominal) 10 A at 40°C; Paralleling: Unlimited units.
The Orion-Tr Smart isolates the service battery from the starter battery, delivering reliable charging even with long cable runs or fluctuating vehicle voltage. It can operate as both a charger and a constant voltage supply to power critical systems when the engine is off or alternator output is limited. Bluetooth connectivity and scalable parallel operation offer future-proofing for growing power needs in boats, RVs, and other vehicles requiring stable 12/24 V charging without risking starter battery discharge.
