Прецизне претварачи струје

Precizni strujni transformatori

Precizni strujni transformatori su namenjeni za elektronska merenja struje, kako naizmenične, tako i jednosmerne, u opsegu od 12,5 A do čak 24 kA. Zahvaljujući izvanrednoj linearnosti i visokoj tačnosti, ovi transformatori se koriste u industrijskim i energetskim aplikacijama, uključujući laboratorije, medicinska istraživanja, sisteme industrijske automatizacije i nadzor parametara mreže. Dostupni su u verzijama za montažu na PCB, sa otvorom za kabl, kao i sa galvanskom izolacijom, što omogućava bezbednu integraciju u analogne i digitalne sklopove.

Precizni strujni transformator - šta treba da znate?

Izlazi transformatora mogu biti standardni 0–10 V, strujni ili digitalni sa RS-485 interfejsom i Modbus protokolom, što omogućava jednostavnu integraciju sa sistemima kontrole i nadzora. Ovi transformatori generišu signal proporcionalan RMS vrednosti struje, omogućavajući precizno merenje struje u aplikacijama snage elektronike, elektro mrežama i automatizovanim sistemima.

U našoj ponudi nalazi se precizni strujni transformator prilagođen različitim potrebama – srdačno vas pozivamo!

Notes:
ⁱ⁾ Linearity measured at DC
^j)Bandwidth is measured under small signal conditions - amplitude of 0.5% I _PN (DC)
^k) All ppm figures refer to V_OUT or I_OUT@ I_PN(DC) except for ITL 900-T where it refers to I_OUT = 600 mA
^l)Electrical offset current + self magnetization + effect of earth magnetic field @ T_A +25 °C
^m) Small signal 5% of I_PN(DC), 32 A_RMS
ⁿ⁾ Small signal40A _RMS
^o) Bandwidth is measured under small signal conditions - amplitude of 1% I_PN(DC)
