The "SST Lightning Resistant Transformer" is a power transformer for low-voltage circuits that reduces induced lightning to 1/1000 of its voltage. Our lightning-resistant transformer determines the winding and shielding methods through computer-aided electric field distribution analysis, allowing for miniaturization while still reducing surge voltage to below 1/1000, thus protecting loads from the threat of lightning surges. 【Features】 ■ Adoption of a new type of Surge Protective Device (SPD) - Achieves miniaturization ■ Elimination of conventional insulator terminals and rationalization of terminal blocks - Makes wiring work smarter ■ Significant increase in surge reduction rate (-60dB) ■ Improvements in shielding methods, winding methods, and insulation methods ■ Compliant with RoHS directives For more details, please refer to the catalog or feel free to contact us.

The "ECL21, ECL41, ECL42 series" is a single-phase dual-winding standard transformer that achieves a maximum reduction of 33% in capacity-to-weight ratio compared to conventional products (50VA to 3kVA), resulting in a compact and lightweight design. By reducing the weight of the transformer, it contributes to the reduction of the weight of equipment and control panels, as well as lowering initial costs. It is designed based on JEM1333-1976 (Japan Electrical Manufacturers' Association) and JEC-2200-1995 (Standards Committee of the Institute of Electrical Engineers of Japan) and complies with domestic regulations. 【Features】 ■ Easy installation and maintenance due to the use of original fittings (Dharma holes) ■ New terminal blocks allow for free wiring from both directions ■ Installation dimensions are almost unchanged from conventional products, making replacement easy ■ RoHS compliant products For more details, please refer to the catalog or feel free to contact us.

The "NS Series" is a noise countermeasure transformer that achieves noise attenuation characteristics, high efficiency, compact size, and lightweight design. With a three-tap specification on the input side, it combines the functions of a power transformer and a noise filter in one unit. It offers four models for the 100V series (100VA to 1kVA) and eight models for the 200V series (100VA to 1kVA). 【Features】 ■ Suppresses power noise and control circuit noise ■ Noise attenuation effects are obtained in both the primary and secondary circuits ■ Effective in suppressing surge voltages generated during ON-OFF switching of motors, etc. ■ The attenuation rate for both normal mode and common mode is below -60dB from 300kHz to 1MHz For more details, please refer to the catalog or feel free to contact us.

The insulation performance has been further upgraded due to the reinforcement of the terminal box and the expansion of the creepage distance (compared to our conventional products).

This trans system is equipped with arresters (lightning protectors) in its primary (input) and secondary (output) circuits. The arrester effectively acts against induced lightning surges or internal lightning phenomena; however, it may not be able to protect the equipment being safeguarded if it encounters impulses beyond its performance or direct lightning surges. The main component of this system, the power transformer, uses high-quality insulating materials at key points to function safely against lightning surges and has an extremely high insulation resistance.
