Charge your 24V batteries using your existing 12V charging source
Yes, it is a DC/DC Boost Converter and DC to DC Battery Charger designed to charge a 24V battery bank from a 12V source (or sources).
Many boats need a 24VDC battery charger that runs off of their 12VDC system. It is becoming more common to have 24VDC batteries running bow thrusters, windlasses, trolling motors, or other large current-draw devices, as well as a 12VDC battery bank supplying the boat's other loads. This DC-DC Marine Battery Charger solves this problem. It also replaces Scheiber and Dolphin Boost Converters used on Jeanneau boats.
It features a user configurable 5-Stage adjustable charge regulation similar to a shore-power charger, so it is compatible with all marine battery types, including AGM, Flooded, VRLA, Calcium, Lithium, etc.
This is also a great refit solution for those wanting to install powerful thrusters or windlasses that must be powered by 24V. Now it is possible to maintain the boat's original 12VDC system while charging the batteries supplying the high current devices via a separate 24VDC battery-powered system.
Rated for marine-duty this step-up DC/DC Converter for boats has galvanically isolated inputs and output, as well as special EMI filtering to eliminate radio frequency noise issues. It is suitable for marine, industrial, military, telecom, and mobile applications. Very high-quality, Made in France.
Most marine-grade DC/DC Converters are very expensive, very heavy and use very old technology. Cristec* solves both problems by using the latest in high-quality power-electronics.
