I-RMNF22TB30 i-3-phase control relay, Harmony Control Relays 8A 2CO overfrequency and underfrequency 208-480V AC

Lokhu kudluliselwa kokulawula kwezigaba ezi-3 kungokwebanga le-Schneider Electric Harmony Control. Lokhu kudluliswa kokulawula kwezigaba ezi-3 kuhlanganiswe nobuchwepheshe be-NFC obuletha ukusebenza kwedijithali esikhundleni sokusebenza kwe-analog. Lena i-8A multifunction 3-phase control relay eqapha isigaba se-3 noma isigaba se-3 ngenethiwekhi ye-Neutral futhi inokubambezeleka kwesikhathi okulungiswayo okungu-0.1s kuya ku-60min. Nge-Harmony NFC App, ama-alamu ahlukene angahlanganiswa kusetshenziswa ingqondo KANYE, NOMA futhi HHAYI ukwenza inhlanganisela yokuqapha ehlukile kokuphumayo okubili kokudluliselwa okulungisekayo ngakunye. I-NFC 3-phase control relay iyireferensi eyodwa esekela imisebenzi engu-7 okungukuthi ukulahleka kwesigaba, ukulandelana kwesigaba, i-Asymmetry, i-Undervoltage, i-Overvoltage, i-Under-frequency, kanye ne-Over-frequency. I-relay yokulawula yezigaba ezi-3 i-IP20 (amatheminali), i-IP40 (izindlu), kanye ne-IP40(iphaneli yangaphambili) ivikelwe. Ngaphezu kwalokho, iphasiwedi enezinhlamvu ezi-4 ithuthukisa ukuvikeleka ngokuvimbela ushintsho olungagunyaziwe lwezilungiselelo.
