コイルボビン式巻鉄心変圧器『NCWトランス』。

狭いスペースにトランスを設置可能！省スペース・軽量・高効率を実現

『NCWトランス』は、“ロ”の字型のコイルボビンに巻線がされ、 コイルボビンの両端に帯状の珪素鋼板が巻き付けられた巻鉄心変圧器。 優れた鉄心素材をムダなく活用しているため、装置重量の大幅削減、作業効率の大幅アップが期待されます。 さらに、1次コイルと2次コイルが完全に独立しているため、高い絶縁性能を実現しました。 ダウンロード資料では、NCWトランス　高効率編・省スペース編・軽量編の3資料にて具体的な数値を用いた資料もご用意しております。 ※詳しくはPDF資料をご覧いただくかお気軽にお問い合わせ下さい。 イプロス未登録の方のお問い合わせは 本文下にある関連リンク 【日幸電機株式会社問い合わせフォーム(※イプロス未登録の方はこちらからお問い合わせください)】 よりお問い合わせください。 ☆★☆★↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓☆★↓↓↓↓↓↓↓↓☆★ ☆★☆★↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓☆★↓↓↓↓↓↓↓↓☆★ ☆★☆★↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓☆★↓↓↓↓↓↓↓↓☆★
