Newmar 115-12-8 Rugged Linear DC Power Supply

The Newmar 115-12-8 is a rugged linear AC-to-DC power supply giving 13.6V nominal at 5A continuous, from selectable 115V or 230V input.

Linear rather than switching design is the deliberate choice, and it trades efficiency for cleanliness. A switching supply generates electrical noise across the radio spectrum. A linear one does not, so it remains the choice for communication equipment where a switching supply would sit in the receiver's noise floor.

Selectable 115V or 230V input at 50/60Hz covers international shore power. That matters on a commercial or work vessel that operates across regions rather than from one home port.

Output is 13.6V nominal, internally adjustable from around 12.6V to 14.5V. Five amps continuous and 8A intermittent suits a radio installation rather than general boat loads, which is what the design is aimed at. Explore more DC-DC converters and power supplies.

• Linear, not switching: cleaner but less efficient
• A switching supply sits in the receiver's noise floor
• 115V or 230V selectable for international use
• 5A continuous suits a radio, not general loads
