Meet the Victron Orion-Tr Smart 12/24-10A (240W) Isolated DC-DC Charger or Power Supply — a versatile, compact solution that powers your service battery while safeguarding your starter battery. With isolation and a wide input/output range, it shines in boats, RVs, or any vehicle where long cable runs or a Euro 5/6 smart alternator can leave charging voltage low.
Why choose the Orion-Tr Smart?
-
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 any Bluetooth smartphone, tablet, or device to monitor, adjust settings, and update firmware with the VictronConnect app. Instant readouts appear on the device list for quick status checks.
-
Smart alternator compatibility: engine running detection helps prevent unwanted starter battery discharge, making it ideal for vehicles with Euro 5/6 engines.
-
Adaptive 3-stage charging for lead‑acid and flexible support for lithium: Bulk – Absorption – Float, with absorption times tuned to prevent overcharging on shallow discharges and ensure full recharge after deep discharges. For lithium, the 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 protected (output current reduces at high ambient temperatures), IP43 rating with downward-oriented screw terminals, and a non-replaceable input fuse for peace of mind.
Designed for practical, real-world use
- Ideal for vehicles with long cable runs or battery banks that require a stable 12/24 V charging solution without risking starter battery discharge.
- Simple installation with screw terminals; no special tools required.
- Flexible operation as either a battery charger or a constant voltage power supply to maintain critical loads.
