Regulator Tegangan Digital Cat (DVR, Digital Voltage Regulator Cat)

------ BERBAHAYA! ------

Regulator Tegangan Digital Cat dapat menimbulkan bahaya tersengat listrik. Bahaya ini akan menyebabkan cedera serius atau kematian.

Hanya percayakan servis kepada personel yang terlatih.

Terminal dan peredam panas menyala (live) pada tegangan yang berbahaya saat daya diberikan dan selama hingga 8 menit setelah daya dihilangkan.

DVR Cat adalah regulator tegangan berbasis mikroprosesor. Daya kontrol untuk DVR Cat disuplai dari sumber eksternal 24 VDC. Tingkat daya dari Cat DVR diperoleh dari generator dengan magnet permanen frekuensi tinggi multi-kutub. Generator dengan magnet permanen frekuensi tinggi multi-kutub dipasang pada ujung poros generator. Koneksi ke DVR Cat dibuat melalui tiga konektor. Komunikasi antara DVR Cat dan peralatan servis dilakukan dengan menggunakan protokol CANBUS.

DVR Cat memiliki fitur berikut:

  • Tiga mode kontrol:

  1. Pengaturan tegangan otomatis (AVR, Automatic Voltage Regulation)

  2. Pengaturan faktor daya (PF, Power Factor)

  3. Pengaturan daya reaktif (VAR, Volt Ampere Reactive)

  • Setelan kestabilan yang dapat diprogram

  • Kontrol soft start dengan setelan waktu yang dapat disesuaikan dalam mode AVR

  • Karakteristik tegangan terhadap frekuensi (V/Hz) dual slope (dua kemiringan)

  • Sensor tegangan tiga fasa atau satu fasa

  • Sensor arus satu fasa

  • Sensor arus medan dan sensor tegangan medan

  • Sepuluh fungsi perlindungan

Menyetel DVR Cat

Untuk melihat dan mengonfigurasikan parameter DVRCat, PC dengan perangkat lunak DVRCat diperlukan.
