It eliminates the problem of increased leakage current due to aging, preventing smoke and fire caused by it. 【Features】 - Achieves miniaturization by connecting MOV and GDT in series with a unique integrated composite structure. - At steady voltage, the GDT has high insulation resistance, allowing it to block the leakage current of the MOV. - Resolves the issue of increased leakage current due to aging, preventing smoke and fire. - Well-suited for AC power supplies that require high reliability, long-term stability, and space-saving design. 【Product Lineup (Excerpt)】 - IsoM3-175 - IsoM3-230 - IsoM3-250 - IsoM5-175 - IsoM5-230 - IsoM5-250 - IsoM8-250 - IsoM8-275 - IsoM8-300 *For more details, please refer to the PDF document or feel free to contact us.
