TSURUTA ELECTRIC CO., LTD. List of Products and Services

The OFGS® (OFF GRID SWITCH BOX) series from Tsuruta Electric is a transformer and control/protection integrated switching panel/transmission system developed to maximize the use of solar storage batteries during both normal and power outage conditions. The OFGS®-H series is a constant power supply system designed for hybrid storage battery systems. During power outages and restorations, it allows for seamless power supply and autonomous operation without the need for manual intervention, thanks to the automatic switching mechanism of the dedicated transformer. This system fully utilizes the capabilities of hybrid PCS without the need to switch between grid (GRID) and off-grid (Off GRID), enabling the realization of corporate renewable energy initiatives such as BCP measures, phase-free operations, and RE100, while addressing installation conditions related to grid connection. It facilitates the construction of a storage battery system that provides clean energy through natural energy (solar power) and off-grid (independent of the power grid) supply, regardless of normal or emergency situations. By packaging "three-phase transformers" + "Scott transformers (for specific single-phase loads)" + "protection devices" + "control devices" into an 'all-in-one package', installation and construction time can be significantly reduced.

The PPSC series of solar power generation allows for power procurement independently, even without electricity from the power company or fuel. It efficiently utilizes the solar energy generated. In the event of natural disasters such as earthquakes and floods, as well as conflicts, terrorism, or unexpected crises, it is not an exaggeration to say that preventing business shutdowns and quickly restoring operations to minimize the impact on the business is a lifeline for companies. Implementing BCP measures tailored to the company is crucial for protecting employees' lives during emergencies like natural disasters, reducing damage as much as possible, and quickly resuming business operations. It is important to prepare with awareness for securing power sources for disaster situations and restoring power within approximately one week. Not only does this facilitate early business resumption, but it also enables power sharing during disasters within the local community. By integrating "PPSC Transformer" + "Protection Devices" + "Control Devices," the self-consumption type solar power generation PPSC simplifies equipment installation and can build a self-consumption system according to installation space and purpose, even in harsh conditions such as salt damage.

■ Capable of manufacturing up to a maximum rated current class of 3000A. We propose optimal designs for the core (silicon steel sheets, Super E, amorphous, Finemet, powdered iron cores, ferrite) and coils tailored to the frequency range, including copper strips, litz wire, and single wire. (1) Considering the structure in terms of IP (Ingress Protection) ratings, we can also provide products that are resistant to harsh environments. (2) Compliance with international standards (IEC/EN/UL, etc.) is available. (3) Direct current superimposition characteristics will be measured. (4) Vibration testing evaluations will be conducted. (5) Slim design is possible. ■ Direct Current Superimposition Characteristics: When a direct current bias flows through an inductor, the permeability decreases as it approaches the saturation point of the magnetic material, resulting in a decrease in inductance value. This characteristic is referred to as direct current superimposition characteristics. The issue with this direct current superimposition current arises when a core with a higher permeability than air is used to achieve a small size with a large inductance. Since cores like iron have a permeability that is significantly greater than that of air, it is possible to achieve a small size with a large inductance.

It has the function of insulation and voltage boosting/reducing for single-phase circuits. Input and output can be connected not only through a terminal block but also through lead wires and connectors. The external shape is basically the same as WECA (vertical) / WECC (horizontal). ■Applicable standard: JEC-2200 ■Insulation class: B.H. ■Capacity: 100VA to 2.5kVA ■Voltage: Please specify the desired voltage for the primary side (P) Please specify the desired voltage for the secondary side (S) ● Explanation and precautions regarding inrush current ● WECC, WECA, and WT transformers use high-performance electromagnetic steel plates (0.2mm) and are designed with a significantly higher magnetic flux density compared to transformers using standard EI cores. On the other hand, the inrush current during excitation is larger, so when replacing with the current transformer, there is a possibility that the overcurrent protection device on the primary side may malfunction. If the protection device on the primary side is the same as the rated current, the likelihood of malfunction becomes very high, so it is necessary to either adopt a product designed to suppress inrush current or increase the rated interrupting current value of the protection device. Since measures against inrush current depend on the compatibility with the protection device, please contact our technical department for special designs and other inquiries.

By implementing DC current prevention functions, it enables clean power supply (202V) to the grid. Additionally, the S series (amorphous) transformers, which reduce standby power at night, are also available, allowing you to choose according to your needs. SPI® Transformers / SPI® Insulated Transformers for Solar Power Generation 【Features】 ■ Complete isolation between the power conditioner and the grid ■ Voltage conversion (converts the output voltage of the power conditioner PCS to a low-voltage wiring voltage of 200V) ■ DC current leakage prevention function ■ Lightning surge prevention function ■ High efficiency and low standby power *For more details, please download the PDF or feel free to contact us. ◇ In the event of a power conditioner failure, the SPI® transformer (DC current leakage prevention transformer) is crucial for addressing DC magnetization issues in pole-mounted transformers. If a failure in the reverse conversion device (power conditioner, inverter) causes DC components to superimpose on the AC current flowing into the grid, the pole-mounted transformer will become DC magnetized, adversely affecting the voltage for consumers other than those with distortion-dispersed power facilities.
