Power supply Orion-Tr 12/12-18A 220W – DC 12V to 12V, 18A output, 220W

Orion-Tr 12/12-18A 220W is a DC-to-DC power supply that accepts a 12 V input and provides a stabilized 12 V output with a maximum continuous current of 18 A and rated power of 220 W. Engineered for vehicle, marine and mobile applications, this module maintains a steady 12 V supply to electronics, charging systems and auxiliary circuits even when the input voltage varies. The compact design and integrated protections make it suitable for use where reliable voltage conversion is required from a 12 V battery source.

Advantages

The unit delivers regulated 12 V output at up to 18 A, supporting a wide range of 12 V devices without significant voltage drop. Built-in protection features guard against common electrical faults and help prevent damage to connected equipment. Its design focuses on stable operation in changing input conditions commonly found in automotive and marine environments, offering a practical solution for powering electronics from a vehicle battery.

Suitable for

• Powering 12 V electronics from a vehicle or boat battery
• Charging auxiliary batteries and maintaining voltage for charging circuits
• Supplying stable power to communication and navigation equipment
• Mobile workshops, service vehicles and recreational vehicles

Key specifications

• Input voltage: 12 V DC
• Output voltage: stabilized 12 V DC
• Maximum output current: 18 A
• Rated output power: 220 W
• Intended use: vehicle, marine and mobile installations

How to use

Connect the input terminals to a 12 V battery or 12 V power source observing correct polarity. Connect the stabilized 12 V output to the load or charging circuit ensuring wiring and connectors suit the current rating. Verify that the total current draw does not exceed 18 A and that wiring and fuses are sized appropriately. Install the unit in a location with adequate ventilation and secure mounting to minimise vibration and exposure to moisture where possible.

Recommendations

Before installation, confirm compatibility with the vehicle’s electrical system and ensure proper fusing on the input and output lines. Use suitably rated cables and terminals, and avoid placing the unit near heat sources. For marine installations, protect connections from corrosion and consider additional enclosure protection. If in doubt, consult a qualified technician for wiring and mounting to ensure safe and reliable operation.
