Victron Orion 48/12-60A DC-DC Converter IP20 48V to 12V 60A

The Victron Orion 48/12-60A DC-DC Converter IP20 (MPN: ORI481260020) is a high-performance, non-galvanically isolated DC-DC converter designed to power 12 V loads from a 48 V DC system. With an input voltage range of 38–66 V, the unit provides a regulated output of 10–15 V and delivers up to 60 A continuously. The output voltage is factory-set to 13.2 V and can be adjusted to the specific application using a potentiometer.

High-performance 48 V to 12 V conversion with adjustable output

• Factory-set to 13.2 V output voltage
• Remote-controlled on/off connection for external device control
• Up to five units can be connected in parallel to increase the available output current
• Suitable for trickle charging a battery
• Temperature-controlled fan cooling
• M6 bolts for the DC connection

Stable 12 V power supply from a 48 V system

The converter is designed to provide a high-performance power supply at a lower voltage level within a 48 V DC system. This allows 12 V loads to be operated without having to provide a separate main power supply for this circuit. Its permissible input voltage range is 38–66 V. In the event of undervoltage, the device shuts down at 38 V and resumes operation once the voltage rises to 40 V. With a continuous output current of 60 A, the model is designed for applications with correspondingly high power requirements. A temperature-controlled fan cooling system aids in heat dissipation during operation.

Output voltage adjustable between 10 and 15 V

An important feature of this Orion model is the adjustable output voltage. It can be set between 10 and 15 V using the built-in potentiometer. The default value is 13.2 V. Always connect a small load to the output during adjustment. Without a load, the measured voltage may be higher than the actual voltage under load. The adjustable output allows the converter to be adapted more flexibly to the requirements of the downstream 12 V circuit. Models with an adjustable output can also be used as battery chargers or for trickle charging a battery.

Remote On/Off for External Control

The Orion features a connection for remote on/off control. This eliminates the need for a high-current switch directly in the input wiring. Remote control can be achieved, for example, via a low-current switch. Another possible application is control via a motor’s run/stop switch.

Parallel Connection for Higher Output Current

If a single unit is insufficient to provide the required power supply, multiple Orion converters with adjustable output can be operated in parallel. Victron specifies that up to five units can be connected in parallel. This allows the available output current to be increased for appropriately sized applications. During planning, the wiring, fuses, and connected loads must be designed to handle the respective total current.

Installation and Operating Conditions

The unit should be installed in a cool, dry, and well-ventilated location. When connecting the unit, first connect the negative lead to the Orion’s negative terminal before connecting the remaining wiring. Otherwise, an incorrect connection of the negative terminal can lead to an overvoltage at the output. The permissible operating temperature range is from -20 to +55 °C. Above 40 °C, the output power is reduced by 3% per °C. In this model, the DC connections are made via M6 bolts. It is also important to note for system planning that this is a non-galvanically isolated DC-DC converter. The input and output are therefore not galvanically isolated from each other. Anyone who requires electrical isolation between the two circuits for their application must select a converter model with the appropriate isolation.
