Uchungechunge lwe-ZY2-40DC lungamadivayisi e-Class C Surge Protection, adizayinelwe ukuvikela kuma-voltage okuqhuma kombani kumanethiwekhi okunikezwa kwamandla e-photovoltaic.Lawa mayunithi kufanele afakwe ngokuhambisana kumanethiwekhi e-DC ukuze avikelwe futhi anikeze ukuvikelwa kwezindlela ezijwayelekile nezihlukile.Imikhiqizo yethu iyatholakala kuma-voltage amakhulu okusebenza ku-photovoltaic: 500,600,800,900 kanye no-1000 Vdc.
