Victron Orion-TR Smart DC-DC 24/24-17 17A (400W) is an isolated DC-DC converter that takes a 24 V input and provides a regulated 24 V output for vehicles and off-grid power systems. With built-in Bluetooth, you can monitor and control charging from a smartphone for effortless setup and management.
-
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: 3-Stage Charge Algorithm—Bulk, Absorption, Float for lead-acid batteries, with absorption time auto-adjusted after shallow or deep discharges; 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 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.
-
Electrical and Physical specs: Input 20–35 V nominal; undervoltage shut down at 14 V; restart at 15 V. Output 24.2 V nominal; 20–30 V adjustable; ±0.2 V; 2 mV rms noise. 17 A continuous at nominal voltage and 40°C; up to 25 A max (10 s); 480 W continuous at 25°C; 400 W at 40°C. Efficiency ~89%. Standby <1 mA; no-load input <80 mA. Isolation 200 VDC galvanic isolation between input, output, and case. Operating -20 to +55°C (derate 3% per °C above 40°C); humidity up to 95% non-condensing. DC Connection: Screw terminals (no special tools).
With the Orion-TR, you’ll have a reliable, isolated DC-DC solution that powers auxiliary electronics while protecting the starter battery. The adaptive charging algorithm optimizes for lead-acid and lithium batteries, reduces risk of overcharging, and provides configuration flexibility to match your battery chemistry and vehicle setup. Bluetooth connectivity enables real-time monitoring, remote control, and firmware updates from the VictronConnect app. Paralleling lets you scale power as your system grows, while the rugged IP43-rated enclosure and engine-shutdown detection ensure compatibility with modern vehicles and off-grid applications.
