Victron Orion-TR Smart DC-DC 24/24-17 17A (400W) Isolated Charger or Power Supply delivers a reliable, isolated 24 VDC input to 24 VDC output solution with built-in Bluetooth for seamless monitoring and control. This professional DC-DC converter adapts to your battery system with an intelligent charging algorithm and easy smartphone integration.
Key features you’ll appreciate include instant readouts via the VictronConnect app, remote on/off capability, and full programmability to suit your battery chemistry and vehicle setup. The Orion-TR is designed to work with smart alternators in modern engines, helping prevent starter-battery discharge when the engine is off.
Smart charging and control at your fingertips
-
Bluetooth Smart Enabled: Monitor, adjust settings, and update firmware from any Bluetooth-enabled device using the VictronConnect app.
-
Instant Readout: Key data, warnings, and alarms are displayed on the device list page for quick diagnostics.
-
Fully Programmable or Fixed Output: Choose a configurable battery charge algorithm or set a fixed output voltage to match your system.
-
Smart Alternator Compatibility: Engine running detection helps prevent discharge of the starter battery when the engine isn’t active.
-
Remote On/Off: Connect a remote switch or relay; H/L terminal options allow switching to battery plus or battery minus (or chassis).
Adaptive charging for any battery type
-
Adaptive 3-Stage Charge Algorithm: Bulk – Absorption – Float for lead-acid batteries, with absorption time adjusted automatically after shallow or deep discharges to prevent overcharging. For lithium batteries, absorption time is fixed (default 2 hours). You can also select a fixed output voltage if preferred.
-
Versatile Output: 24.2 V nominal output with adjustable range from 20–30 V and a tight tolerance of ±0.2 V. Output noise is a low 2 mV rms.
-
Paralleling Capability: Short-circuit proof and can be paralleled with an unlimited number of units to increase total output current.
Rugged, vehicle-ready design
-
Suitable for Vehicles with Smart Alternators: Euro 5 and Euro 6 engines are supported via engine shutdown detection.
-
IP43 Protection: Protected when installed with screw terminals facing downward; robust for on-the-road and off-grid use.
-
Remote Control and Safety: Remote on/off and a built-in 2-pole connector provide flexible installation options.
