12V-48V DC Power Supplies

Keep Radios, Navigation, and Control Gear on Stable DC Power

When communications, chartplotters, and safety electronics must stay online, a cheap adapter is not enough. These DC power supplies convert 115/230V AC shore or generator power into tightly regulated 12V and 24V DC so sensitive gear runs quietly, holds voltage through load swings, and lasts longer in salt air and vibration.

Choose rugged Newmar linear marine supplies from compact 8-amp units through high-capacity 35-amp CD models, Power-Pac systems with built-in battery backup, and VMAX 12V chargers that double as compact DC power supplies.

Protect Electronics from Dirty Power

Linear circuitry delivers noise-free output with extremely low ripple so VHF, AIS, and nav electronics hear clean signals instead of hash. Tight 1% line-and-load regulation holds voltage steady as loads change, which means fewer resets and longer life for expensive equipment.

• Noise-Free Output – Keep radios and displays free of ripple and switching interference.
• 1% Regulation – Hold voltage within one percent under rated line and load so instruments stay locked and stable.
• Built-In Protection – Overvoltage, current limit, thermal overload, and input/output fusing guard both the supply and the load.

Match Voltage and Amperage to the Job

Select 12V or 24V output and size amperage to the radios, plotters, and control gear you need to support. Compact units handle a dedicated comms circuit. High-capacity CD models with cooling fans deliver continuous current for larger electronics suites on commercial vessels, workboats, and yachts.

• 12V and 24V Banks – Power common marine and industrial DC systems from the same trusted platform.
• 8A to 35A Output – Scale from a single transceiver to a full navigation suite.
• 115/230V Input – Switch shore or generator voltage at the panel and stay ready in any port.

Stay Online When Shore Power Drops

Power-Pac supplies float and charge an onboard backup battery while AC is present, then take over automatically the instant shore or generator power disappears. A 7Ah pack can run a 25-watt transceiver for hours on a typical duty cycle; step up to 14Ah when you need more reserve. Low-battery alarms and disconnect protect the pack, with an override for true emergencies.

Specific VMAX 12V Chargers double as DC Power Sources

Need a clean 12V source in the shop or a dedicated lithium maintainer at the dock? VMAX 5A to 20A chargers and maintainers keep AGM and LiFePO4 batteries at the right voltage and give you a portable DC supply for testing, commissioning, and everyday use.

Specify Gear Built for Salt, Shock, and the Long Watch

Conformal-coated boards, powder-coated aluminum heat-sink cases, and integral shock mounts survive the marine environment. Heat-sink fins and thermally activated fans on CD models keep output stable during continuous duty. Browse the full range, match voltage and amperage to your load, and put clean DC on the bus before the next voyage.
