Victron Energy Orion-Tr Isolated DC-DC Converter, 360-400W, IP43

Overview

The Victron Energy Orion-Tr Isolated DC-DC Converter is a 360-400 W galvanically isolated converter range for matching 12 V, 24 V or 48 V DC supplies to onboard DC loads that need a stable output voltage. It is used when one DC system on the vessel needs to feed equipment on another voltage, such as running 24 V electronics from a 12 V service bank or supplying 12 V loads from a 24 V or 48 V installation.

The range covers 12 V, 24 V and 48 V input systems, with nominal output options of 12.2 V, 24.2 V and 48.2 V depending on the selected model. Output voltage is adjustable across the matching range, with 10-15 V for 12 V output models, 18-30 V for 24 V output models and 40-60 V for 48 V output models.

For marine electrical work, the important details are the isolation and installation format. The unit has 200 VDC galvanic isolation between input, output and case, screw-terminal DC connections, low 2 mV rms output noise and an operating temperature range of -20 to +55 °C with derating above 40 °C.

Key features

• Galvanically isolated conversion helps separate DC circuits and reduce ground-loop issues between onboard systems.
• Input options cover 12 V, 24 V and 48 V battery systems, with matching 12 V, 24 V and 48 V output configurations across the range.
• Continuous output power is 360 W, 380 W or 400 W at 40 °C depending on the voltage and current configuration.
• Remote on/off terminal allows switching from a low-current control circuit, so a high-current switch is not needed in the main input wiring.
• Adjustable output voltage supports fine tuning for the connected DC load within the correct output voltage range.
• Short-circuit proof output and parallel operation support installations that need more available output current.
• IP43 protection applies when the converter is mounted with the screw terminals facing downward.
• Screw terminals accept cable up to 16 mm² or AWG6, which suits higher-current DC runs when installed with the correct fuse and wiring plan.

Variants

This product family varies by input voltage, output voltage and continuous output current. The available configurations cover 12 V to 12 V, 12 V to 24 V, 12 V to 48 V, 24 V to 12 V, 24 V to 24 V, 24 V to 48 V, 48 V to 12 V, 48 V to 24 V and 48 V to 48 V conversion.

Output current ranges from 8 A to 30 A across the range. The Orion-Tr isolated platform, remote on/off terminal, screw-terminal DC connections, 200 VDC galvanic isolation, 2 mV rms output noise and -20 to +55 °C operating temperature range remain consistent across these 360-400 W models.

Installation and fit

Mount the converter in a dry, ventilated electrical space with access to the screw terminals and enough clearance for heat dissipation. The IP43 rating depends on mounting orientation, so the screw terminals should face downward where splash protection matters.

Size the wiring, fuse protection and cable runs around the selected voltage and output current. The 12 V input and 12 V output models have a 130 x 186 x 80 mm body and weigh about 1.8 kg, while the other models measure 130 x 186 x 70 mm and weigh about 1.6 kg.

Electrical and system integration

The remote on/off terminal is useful on boats where the converter should follow an ignition signal, engine run signal, battery switch logic or a small control switch at the helm or panel. When disabled through the remote port, current consumption is below 200 µA, which helps reduce standby draw on stored vessels.

This converter is for stable DC power conversion, not dedicated battery charging. For house-to-start or alternator-to-service battery charging applications, a DC-DC charger from the appropriate charging range should be used instead.

Use on board

This range fits refits and new builds where different DC voltages coexist on the same vessel. It is a practical match for powering electronics, controls, communications equipment, lighting circuits or auxiliary DC loads when the required load voltage does not match the battery bank voltage.

The isolated design is especially useful on boats with mixed equipment grounds, sensitive electronics or separated DC subsystems where clean circuit separation matters as much as voltage conversion.
