Milesight CT101 – Smart Current Transformer (LoRaWAN, CT10x Series)
Overview
Trafo arus pintar nirkabel berdesain split-core yang dapat dilepas, dipasang menjepit pada kabel tanpa memutus sirkuit. Menghasilkan daya dari arus kabel yang diukur, sehingga tanpa baterai. CT101 mengukur sampai 100 A; seri CT10x juga mencakup CT103 (250 A) dan CT105 (500 A).
Fitur Utama
- Dipasang tanpa mematikan sirkuit dan tanpa mengubah kabel
- Tanpa baterai : daya dari arus yang diukur; arus minimum pelaporan 1,4–1,5 A
- Pengambilan sampel 3,3 kHz menangkap lonjakan arus singkat
- Pelaporan energi kumulatif (Ah, atau kWh bila tegangan dan faktor daya diatur)
- Empat jenis alarm : arus, over-current, suhu, dan tegangan rendah
- Sensor suhu kabel eksternal dan antena dapat dipilih (termasuk magnetik untuk panel logam)
- Modul nirkabel terpisah supaya sinyal tidak terhalang panel logam
- Pembaruan jarak jauh (FUOTA) dan integrasi BMS lewat gateway
Sederhananya: perangkat ini cocok untuk memantau arus per sirkuit (AC, pompa, penerangan, panel distribusi) tanpa menghentikan operasional.
