Charging system for underwater drone operations, expandable up to 12,800W in a 19-inch rack 1U.
In marine development and underwater drone operations, a stable power supply is required to support long hours of investigation and work. Particularly, the reliability of the system and space-saving design are extremely important for operations in limited onboard space and for battery charging that requires high output. Power supply troubles can lead to interruptions in investigations and risks of equipment damage, making the establishment of a charging environment with redundancy and stability essential. The DBR Series features a slim 1U design for 19-inch racks, yet can expand output up to 12,800W through parallel connections, and is designed to minimize the impact on the entire system even if some units encounter problems, thanks to the built-in OR-ing FET. 【Usage Scenarios】 - Installation in the limited rack space of research and work vessels - Efficient charging of large-capacity batteries for underwater drones - Stable power operation during long-term marine investigations 【Benefits of Implementation】 - The 1U slim design allows for effective use of limited onboard space - Flexible output expansion through parallel connections enables system construction tailored to equipment configurations - The built-in OR-ing FET maintains system operation even in the event of unit failure.
