OFGS® Series Switchboard for Industrial Storage Battery Systems
OFGS® Series Off-Grid Switch Box (OFGS is a registered trademark of Tsuruta Electric Co., Ltd.)
Switchboard for industrial storage battery systems optimal for medium-sized enterprises/small and medium factories (three-phase Scott transformer + controller + protector), flexible response to major battery manufacturers.
The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a transformer and control/protection integrated switchboard developed to maximize the use of solar/industrial storage batteries during both normal and power outage conditions, ensuring the protection of solar power generation equipment and enabling safe electricity supply. This product, specifically designed for industrial storage battery systems, simplifies design and construction by packaging "three-phase transformer" + "Scott transformer (dry-type Scott transformer)" + "protection devices" + "control devices" into an "all-in-one package." It completely isolates the power converter (PCS) and cubicle (system/power), protecting power generation facilities and factory lines, while also improving generation efficiency. Additionally, options such as fire prevention regulation compliance products and salt damage countermeasures are available. During a power outage, users can choose between two types of switching to off-grid mode: "manual switching" or "semi-automatic switching."
