Newmar Power

Newmar Marine Power Supplies

When communications, navigation, and onboard electronics must stay online, Newmar Power delivers the clean, regulated DC those systems demand. For more than fifty years, Newmar has engineered mission-critical power products for commercial vessels, workboats, yachts, telecom sites, and public-safety networks. Shop the Newmar Power collection at GMI Energy and keep radios talking, instruments stable, and crews confident—even when shore power drops.

Dependable DC Power When Uptime Matters

Newmar Power products protect the equipment you cannot afford to lose. Highly regulated linear circuitry feeds radios and navigation electronics with noise-free 12-volt or 24-volt output, so you hear clear transmissions instead of interference. Tight 1% line-and-load regulation and extremely low ripple hold voltage steady as loads change, which means fewer resets and longer life for expensive electronics.

Choose the configuration that matches your mission:

• Power-Pac 12V supplies with built-in 7Ah or 14Ah battery backup keep VHF and critical nav gear running the moment AC power fails.
• Heavy-duty 115/230 VAC to 12V or 24V power supplies deliver continuous output from compact 8-amp units through high-capacity 35-amp CD models with cooling fans.
• Selectable dual-voltage AC input lets the same unit work on U.S. dock power or 230-volt systems abroad.

Stay On the Air During a Power Loss

The Newmar Power-Pac is built for stations that cannot go silent. While AC is present, the supply powers your load and float-charges sealed backup batteries. The instant shore or generator power disappears, those batteries come online automatically. A 7Ah Power-Pac can run a 25-watt transceiver for hours on a typical duty cycle; step up to 14Ah when you need more reserve. Low-battery alarm and disconnect protect the pack, with an override for true emergencies. That uninterruptible DC path is why commercial vessels, workboats, and yacht skippers specify Power-Pac for radios and GMDSS-critical gear.

Rugged Hardware Built for Salt, Heat, and Vibration

Newmar designs these supplies for engine rooms and electronics lockers—not climate-controlled offices.

• Polyurethane conformal-coated circuit boards resist moisture and salt air.
• Powder-coated aluminum heat-sink cases and integral shock mounts absorb vibration and shed heat.
• Overvoltage protection, current limiting, thermal shutdown, and input/output fusing guard both the supply and the load.
• Thermally activated fans on CD models keep high-amp units cool during continuous duty.

Proven linear circuitry delivers quiet output and long service life. Many units can be configured as battery chargers or fitted with a transfer relay so an external bank takes over if AC fails.
