Newmar 115-12-8 Power Supply

Ensure reliable power for your marine communication and navigation systems with the 115-12-8 Power Supply. Designed for commercial vessels, this robust DC power supply delivers consistent 12-volt power, essential for critical onboard equipment, even in the most demanding maritime environments.

Key Features

• Superior Voltage Regulation: Maintains output voltage within 1% across all rated line and load conditions, ensuring stable performance.
• Durable Construction: Features a polyurethane conformal-coated PC board and a corrosion-resistant heavy-duty aluminum case with integral shock mounts, perfect for harsh marine conditions.
• Efficient Cooling: Large heat sink fins effectively dissipate heat from semi-conductors, promoting cool and reliable operation.
• Comprehensive Protection: Equipped with overvoltage protection, current limiting (set at 105% of intermittent rating), thermal overload protection, and input/output fusing to safeguard your equipment.
• Thermally Activated Cooling: Includes a cooling fan on “CD” units that activates based on temperature, ensuring optimal thermal management.
