Switchboard for Industrial Storage Battery Systems OFGS(R) Series
Switchboard for industrial storage battery systems suitable for medium-sized enterprises/small and medium-sized 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 integrated control and protection switchboard developed to maximize the use of solar and industrial storage batteries during both normal and power outage conditions, ensuring the protection of solar power generation equipment and enabling a safe electricity supply. This product, specifically designed for industrial storage battery systems, simplifies design and construction by packaging "three-phase transformers" + "Scott transformers (dry-type Scott transformers)" + "protection devices" + "control devices" into an "all-in-one package." It completely isolates the power conditioner (PCS) and cubicle (system/power), protecting power generation facilities and factory lines, while also improving power generation efficiency. Additionally, options such as compliance with fire prevention regulations and measures against salt damage are available. During power outages, users can choose between two types of switching to off-grid mode: "manual switching" or "semi-automatic switching."
basic information
Industrial Storage Battery System Switchboard Transformer OFGSⓇ (OFF GRID SWITCH BOX) Series ■ Simplification of facility construction through the packaging of three-phase transformers + Scott transformers + protective devices + control devices. ■ Off-grid (self-sufficient power) system compatible: During power outages, switching to off-grid mode (disconnected from the power grid) can be selected from two options: manual or semi-automatic switching. ■ Compatible with various major battery manufacturers. ■ Prevention of leakage current through the function of isolation transformers. ■ Voltage conversion (output voltage converted to 210V). ■ Equipped with lightning surge protection. ■ High efficiency and low standby power. ■ Capable of accommodating various combinations of PCS (power conditioning systems). ■ Installation of power analyzers (optimal for solar power self-consumption, detecting load and generation in real-time to control generation). ■ Adoption of a unique complete insulation method to prevent solar power systems from becoming inoperable due to leakage alarms, ensuring safe electricity supply. ■ Compliant with fire prevention regulations (FR option) available. ■ Salt-resistant and heavy salt-resistant specifications (ST option) available.
