BECKHOFF EL3443 — aniq 3 fazali quvvat o‘lchovi va tarmoq tahliliga optimallashtirilgan, 3 kanalli analog kirishli EtherCAT terminali. 480 V AC/DC gacha bo‘lgan kuchlanishlar va 1 A AC/DC gacha bo‘lgan toklarni bevosita yoki o‘lchash transformatorlari orqali qabul qila oladi hamda 24 bitli aniqlikda ma’lumotlarni yig‘ishni ta’minlaydi. Ushbu terminal energiya sarfini monitoring qilish, elektr ko‘rsatkichlarini hisoblash va elektr tarmog‘ining umumiy sifatini baholash uchun kompleks vosita vazifasini bajaradi.

Asosiy tok va kuchlanish o‘lchovlaridan tashqari, BECKHOFF EL3443 aktiv, reaktiv va to‘liq quvvatni, shuningdek aktiv, reaktiv va to‘liq energiyani hisoblaydi. Qo‘shimcha diagnostika qiymatlariga faza burchagi (cos phi), chastota, umumiy garmonik buzilish (THD) hamda 40-garmonikagacha bo‘lgan alohida garmonikalar kiradi. Ushbu integratsiyalangan imkoniyatlar yordamchi o‘lchash asboblarisiz tarmoq va yuklamani to‘liq kuzatish imkonini beradi.

Tizim xavfsizligi va aloqa yaxlitligini ta’minlash uchun terminal maydon tomondagi o‘lchash zanjirlari bilan ichki E-bus o‘rtasida 2500 V elektr izolyatsiyasiga ega. Integratsiyalangan monitoring funksiyalari fazalar ketma-ketligi, faza yo‘qolishi, fazalar asimmetriyasi hamda sozlanadigan past yoki ortiqcha kuchlanish chegaralarini qamrab oladi. Aniq nol kuchlanish kesishuvini aniqlash ham aniq sinxronlashtirish talab etiladigan qo‘llanilishlar uchun mavjud.
