Tushuntish
Asosiy Texnik Parametrlar
NG7-17.5 seriyasi klyuch modul bo'lib butunlay yoqilg'an va butunlay yoqilg'an ortacha boshqaruv tarmog'i uchun sheberga mo'ljallangan tarmoq klyuchi dir. U ichki va tashqi foydalanishda mumkin. Ichki foydalanishda ko'p komponentlar ichki ochish va yopish joylari uchun zavoddan chiqarilganda maxsus asboblar bilan o'rnatilishi mumkin. Klyuchning quvvat qismi IP67 darajadagi himoyaga ega. Tashqi foydalanishda kutinin himoya darajasi IP54 bo'lib asosan ortacha boshqaruv tarmog'i uchun mo'ljallangan. Jismoniy ta'sir sifatida yuqori balandlik, kondensatsiya, to'nos, kichik hayvonlar va kimyoviy vositalar ga moslashadi. Kichik hajmda bo'lib servisga yoqtirilmaydi, shahar savdo markazlari, sanoat yig'ilish joylari, aeroflottar, avtomobil yo'llari va boshqa tarmoq tizimlari da keng foydalaniladi. Bu bir qatorli tarmoq uchun moslashuvchan foydalanishga hamda dual energiya ta'minotining o'zini ta'minlashiga moslashgan holda energiya ta'minotining niqobxonligini ta'minlashga moslashgan. Yuborishdan oldin barcha bizning modullar zavodda sinovdan o'tkaziladi.
