Nauti-Tech Systems proudly introduces the SPM V-Series © (previously known as the Nauti-Combine V-Series), our all-in-one power management distribution system. With over 20 years in the yacht industry, our power combiner was designed with the end-user's convenience and safety in mind.
The NC-V Series features unique capabilities, including Shore Power combining, single or dual load bus, plus full generator control with Seamless transfer. Seamless transfer prevents inconvenient blackouts and downtime when switching from shore power to generator, or between generators. Important values such as voltage, current, and frequency are monitored and metered to assist in making important decisions like a safe disconnect.
Combined with smart load balancing, load shedding, appliance prioritization, and reverse polarity correction, the NC-V-Series easily meets all power demand requirements and more. To provide a complete solution, our NC-V Series is also fully compatible with the Nauti-Boost & Hubbell controllers, including all other isolation or boost transformers. To complete this package, our entire system can be paired with our HMI daisy-chainable display for quick and easy access and can be integrated to your systems via Canbus, Modbus or TCP/IP.
