SISTEM BATTERY CHARGER INDUSTRIAL
Battery Charger PMI dikendalikan oleh thyristor, sepenuhnya digital, statis. Penyearah AC/DC dengan karakteristik tegangan konstan/arus konstan. Isolasi galvanik disediakan dengan input transformator. Battery Charger dilengakapi dengan fasilitas komunikasi dengan system SCADA melalui terminal free contact dan berbagai fitur komunikasi (protokol Modbus; RS-485 atau port TCP/IP).
Battery Charger PMI banyak digunakan di berbagai industri seperti Pembangkit Tenaga Listrik, Distribusi Tenaga Listrik, Transmisi Tenaga Listrik, Manufaktur, Transportasi, Pertambangan, Minyak & Gas dengan berbagai aplikasi yang berbeda seperti Alarm, Kontrol, Sinyal dan Pasokan Pemutus Arus DC pada Pembangkit Listrik, Gardu Induk, Switchgear, Kereta Api, dan serta Pabrik Lepas Pantai
