1. Latar Belakang Masalah: Anomali yang Disebabkan oleh Catu Daya Universal<\/strong><\/h4>\n\n\n\n

Selama penggunaan pengukur level ultrasonik seri KUS dengan catu daya universal 220 V hingga 24 V\/12 V, pelanggan menghadapi dua masalah utama:<\/p>\n\n\n\n

    \n
  1. Kegagalan komunikasi serial (gangguan komunikasi RS485);<\/li>\n\n\n\n
  2. Penyimpangan pengukuran (jarak aktual 3 m menunjukkan fluktuasi sekitar 1 m).
    Modul daya yang telah diuji:<\/li>\n<\/ol>\n\n\n\n
      \n
    • Modul 220 V AC ke 24 V DC<\/li>\n\n\n\n
    • Modul konversi 220 V AC ke 12 V DC<\/li>\n<\/ul>\n\n\n\n

      Tabel 1: Langkah-langkah dan Hasil Pengujian Modul Daya 12V<\/strong><\/p>\n\n\n\n

      Langkah Pengujian<\/th>Rincian Operasi<\/th>Hasil Uji<\/th><\/tr><\/thead>
      1. Pengukuran Gelombang<\/td>Probe osiloskop yang terhubung ke V+ dan V-, kopling AC, batas lebar pita 20 MHz<\/td>Ripple: gelombang segitiga 20\u201330 mV, sehingga dapat dikesampingkan bahwa ripple merupakan penyebab kesalahan pengukuran<\/td><\/tr>
      2. Uji Tanpa Pengardean<\/td>Modul daya tidak terhubung ke ground, sensor mengukur jarak aktual 3 m<\/td>Hasil pengukuran berfluktuasi di sekitar 1 m, penyesuaian ambang batas tidak valid; kembali normal setelah beralih ke catu daya meja<\/td><\/tr>
      3. Uji dengan Pengardean<\/td>Modul daya telah dihubungkan ke ground, kabel sensor dijauhkan dari kabel 220V<\/td>Pengukuran akurat (3 m); kesalahan muncul kembali saat kabel berada di dekat kabel bertegangan 220 V<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      3. Pengujian Modul Daya 24 V DC dan Analisis Kegagalan Komunikasi<\/strong><\/h4>\n\n\n\n

      Penyebab utama kegagalan komunikasi<\/strong>:<\/p>\n\n\n\n

        \n
      • Tegangan mengambang pada terminal V+ dan V- menimbulkan perbedaan potensial antara sinyal RS485 dan ground, sehingga menimbulkan gangguan.<\/li>\n\n\n\n
      • Solusi: Hubungkan GND ke V- untuk menghilangkan beda potensial (Gambar 4).<\/li>\n<\/ul>\n\n\n\n

        4. Empat Poin Utama dalam Adaptasi Daya Universal (Ringkasan)<\/strong><\/h4>\n\n\n\n
          \n
        1. Prioritas Grounding<\/strong>: Modul daya harus di-ground dengan baik agar tegangan V- sejajar dengan potensial bumi;<\/li>\n\n\n\n
        2. Tanah Sinyal Bersama<\/strong>: Hubungkan GND ke V- untuk menghilangkan perbedaan potensial pada RS485;<\/li>\n\n\n\n
        3. Isolasi Kabel<\/strong>: Jaga jarak \u226530 cm antara kabel sensor dan kabel listrik 220 V;<\/li>\n\n\n\n
        4. Peringatan Keselamatan<\/strong>: Pastikan kabel sensor tidak bersentuhan dengan tegangan tinggi 220 V untuk menghindari sengatan listrik.<\/li>\n<\/ol>\n\n\n\n

          5. Perbandingan Bentuk Gelombang dan Penekanan Gangguan<\/strong><\/h4>\n\n\n\n

          (1) Gangguan V+ ke ground (tanpa ground)<\/strong>: 42,8 V puncak-puncak, gangguan jaringan listrik 50 Hz ;<\/p>\n\n\n\n

          \"\"<\/figure>\n\n\n\n

          (2) Sinyal RS485 (terhubung ke ground)<\/strong>: Gangguan telah diatasi, stabilitas komunikasi 100%. .<\/p>\n\n\n\n
