Victron Orion 48/12-60A DC-DC Converter, Non-Isolated

The Victron Orion 48/12-60A converts the DC voltage of a 48-V system into a stable, adjustable 12-V supply. With a continuous current of 60 A, the DC-DC converter is also suitable for high-power 12-V loads and larger 12-V sub-distribution systems.

The input voltage range of 38 to 66 V is designed for 48-V battery and vehicle electrical systems. The output provides an adjustable voltage range of 10 to 15 V; the Orion is factory-set to 13.2 V. This allows 12-V devices to be powered from a 48-V system and suitable 12-V batteries to be buffered.

High-Performance 12-V Power Supply from a 48-V System

The Orion continuously outputs up to 60 A Ready. The maximum output current is 65 A. This allows an existing 48-V power system to supply a separate 12-V sub-network without having to operate an additional 12-V power source.

The 92% efficiency reduces conversion losses. A temperature-controlled forced-air cooling system supports operation under high loads. According to the manufacturer, a power reduction of 3% per degree Celsius can be expected at temperatures above 40 °C.

The Key Benefits

• 48 V to 12 V: Powering 12-V loads from a 48-V battery or vehicle electrical system.
• 60 A continuous current: Sufficient power for larger 12-V power distribution systems and multiple loads operating simultaneously.
• Adjustable from 10 to 15 V: Adjustment of the output voltage via the built-in potentiometer.
• 92% efficiency: Efficient conversion within the specified operating range.
• Remote On/Off: External control without a high-current switch in the input wiring.
• Parallel Operation: Up to five devices can be connected in parallel to increase the available output current.
• Buffer loading is possible: Suitable for constant-voltage buffer charging of a compatible 12-V battery.
• Compact design: 65 × 88 × 195 mm and weighing 0.9 kg.

Suitable Applications

The Victron Orion 48/12-60A is designed for systems that require a high-power 12-V supply from a 48-V source. Typical applications include:

• Adventure and expedition vehicles with a 48-volt electrical system and 12-volt electrical components
• Boats and yachts with a combined 48-V and 12-V DC system
• Mobile workshops, commercial vehicles, and specialty vehicles
• Off-grid systems and standalone systems with a 48-V battery bank
• Stationary energy, industrial, and commercial systems with 12-volt auxiliary loads
• Powering a suitable 12-V starter or auxiliary battery from a 48-V system

Depending on the design, potential 12-V loads may include, for example, lighting, communications equipment, control systems, pumps, navigation electronics, or a central 12-V sub-distribution panel. The sum of the continuous loads and any inrush currents must remain within the device’s limits.

Adjustable output voltage from 10 to 15 V

The output voltage is adjusted using a potentiometer. The factory default setting is 13.2 V. With an adjustment range of 10 to 15 V, the voltage can be adjusted to match the intended load or the permissible float voltage of a battery.

Buffer charging instead of a multi-stage charging characteristic curve

Since the output voltage is adjustable, the Orion can be used for Buffer charge or maintenance charge It can be used with a suitable 12-V battery. The set voltage must be compatible with the battery chemistry, battery type, and manufacturer's specifications.

The device operates at a set constant voltage and does not have a multi-stage, battery-specific charging curve. For applications that require controlled bulk, absorption, and trickle charging or a temperature-dependent charging strategy, a DC-DC battery charger designed for this purpose must be used.

Remote On/Off and Parallel Operation

The green remote on/off connector allows the converter to be controlled by an external switch. The switching current is less than 100 mA. This eliminates the need for an additional high-current switch in the input line. Depending on the system, the control can be linked, for example, to an operating signal or a run/stop signal.

If 60 A is not sufficient, Victron states that up to five adjustable Orion inverters can be operated in parallel. The electrical design, fusing, wiring, and even current distribution must be properly sized to accommodate the resulting total current.

Installation and Compatibility

The Orion is equipped with M6 bolts for the DC connections. Due to the high output current, it is essential to use cables with appropriate cross-sections, keep cable runs short, use correctly rated fuses, and ensure that connections are made properly. The specific sizing depends on cable length, installation method, ambient temperature, and applicable installation regulations.

The device is designed for a A cool, dry, and well-ventilated installation location intended. The IP20 version is not suitable for unprotected installation in wet, dusty, or exposed-to-the-elements areas.

Technical Specifications of the Victron Orion 48/12-60A

Conclusion

The Victron Orion 48/12-60A is a compact solution for high-power 12-V loads in a 48-V system. Its strengths lie in its high continuous current, adjustable output voltage, external on/off control, and the ability to operate multiple units in parallel.

When selecting a product, it is crucial to ensure that there is no galvanic isolation and that buffer charging with a constant voltage does not replace a full battery charge with a multi-stage charging curve.

Frequently Asked Questions About the Victron Orion 48/12-60A

• What is the Victron Orion 48/12-60A used for?

  
  

  The DC-DC converter supplies power to 12-V loads from a 48-V battery or vehicle electrical system. It is suitable, for example, for vehicles, boats, off-grid systems, and stationary systems with a separate 12-V sub-system.

• Is the Orion 48/12-60A galvanically isolated?

  
  

  No. The device is not electrically isolated. There is no electrical isolation between the input and output sides. For systems requiring galvanic isolation, an isolated model is necessary.

• Can the Orion charge a 12-volt battery?

  
  

  The adjustable output allows for buffer or trickle charging of a suitable 12-V battery. The voltage must be set according to the battery manufacturer's specifications. However, the Orion has No multi-stage charging characteristic curve and therefore does not replace a full-featured DC-DC battery charger in every application.

• How do you adjust the output voltage?

  
  

  The voltage is adjusted via a potentiometer between 10 and 15 V. The factory setting is 13.2 V. According to Victron, a small load must be connected to the output during adjustment.

• Can multiple Orion 48/12-60A units be operated in parallel?

  
  

  Yes. Victron allows up to five devices with adjustable outputs to be connected in parallel. The wiring, fuses, and power distribution must be properly configured to handle the higher total current.

• Can the converter be turned on and off externally?

  
  

  Yes. The device can be controlled via the green remote on/off connector using an external switch or a suitable control signal. The switching current is less than 100 mA.

• Where can the Victron Orion be installed?

  
  

  Victron requires a cool, dry, and well-ventilated installation location. Due to its IP20 rating, the converter must be protected from moisture, dirt, and direct exposure to the elements.
