NewMar DC to DC Converters

NewMar DC to DC Converters: Precision Voltage Conversion for Demanding Environments

When onboard electronics depend on clean, regulated power, the DC to DC converter sitting between your battery bank and your navigation or communication gear becomes one of the most critical components on a vessel. NewMar has spent more than 50 years engineering DC power products with the kind of reliability that mission-critical applications demand — and their DC to DC converters stand as one of the clearest expressions of that engineering philosophy.

Three Focused Product Lines

NewMar approaches DC-to-DC voltage conversion through three distinct series, each tailored to a specific application profile:

• Standard Series — NewMar's Standard Series DC to DC converters accept a wide 20–50 VDC input and deliver a regulated 12 or 24 VDC negative-ground output at 3 to 50 amps, making them well suited for powering communication and navigation equipment on negative-ground systems.
• Isolated Series — Designed for positive-ground applications or installations where electrical isolation is essential, the Isolated Series can step the voltage up, down, or maintain it at the same level. Output voltage is held within 1% under all line and load conditions within rating — a level of stability that voice, data, and navigation transceivers depend on.
• 12V to 24V Step-Up Converters — These "up" converters produce 24 volts from a 12-volt system, making them ideal for managing dual-voltage applications aboard vessels and vehicles without the expense and complexity of installing a separate 24-volt battery bank and charging system.

Built for the Marine Environment

What separates a NewMar converter from a generic off-the-shelf unit is the attention to environmental hardening. Units in the Isolated Series, for example, feature polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum cases with heavy-duty shock mounts — details that matter on a working boat exposed to salt air, vibration, and moisture. Large heat-sink fins maximize air contact for cooler operation, extending component life over the long run.

Protection circuitry is equally thorough: current limiting, automatic thermal shutdown, short-circuit protection, and reverse polarity and overvoltage protection are all built in. Even if the input voltage fluctuates — as it naturally does with a charging or discharging battery — the output remains stable, keeping sensitive electronics operating correctly.

A Manufacturer with Real Engineering Depth

NewMar is part of Mission Critical Electronics and operates out of a 30,000-square-foot facility where in-house metal fabrication, CNC machining, and assembly allow tight quality control over every unit produced. The brand serves marine, telecommunications, public safety, land mobile, and industrial automation sectors — meaning the converter designs are validated across some of the most demanding duty cycles in the power electronics industry. For boaters, that cross-industry engineering heritage translates directly into products that hold up watch after watch, season after season.
