The ONWA KRP-150DC is a regulated marine power supply unit. It is designed to provide stable DC power to sensitive onboard electronics, such as radar antennas and chartplotters, ensuring they are protected from the voltage fluctuations common in a vessel’s electrical system.

The KRP-150DC acts as an essential “clean power” source for high-draw marine equipment. It is frequently bundled with or required for ONWA Radar Antennas (like the KRA-3002 or KRA-4001 open-array series) to convert and regulate the ship’s battery power into a steady, filtered voltage.

• Voltage Regulation: Maintains a precise output even as the engine starts or other heavy loads (like winches) cause the house battery voltage to dip or spike.

• Protection Circuitry: Features built-in safeguards against over-voltage, short circuits, and reverse polarity, which are critical for protecting expensive navigation processors.

• Marine-Grade Build: Housed in a durable, heat-dissipating casing designed for the high-temperature and high-vibration environment of a typical engine room or helm console.
