YCRP-C ceev ceev Device

General
Cov khoom siv-theem ceev ceev kaw lub thawv PLC yog cov cuab yeej uas koom tes nrog cov khoom siv hluav taws xob nrawm nrawm los tsim lub photovoltaic DC sab nrawm kaw qhov system, thiab cov cuab yeej ua raws li American National Hluav Taws Xob Code NEC2017 & NEC2020 690.12 rau kev kaw sai ntawm photovoltaic chaw nres tsheb fais fab. Cov lus qhia tshwj xeeb xav kom lub tshuab hluav taws xob photovoltaic ntawm txhua lub tsev, thiab lub voj voog dhau 1 ko taw (305 mm) los ntawm photovoltaic module array, yuav tsum poob qis dua 30 V hauv 30 vib nas this tom qab pib kaw sai; Lub Circuit Court nyob rau hauv 1 ko taw (305 mm) los ntawm PV module array yuav tsum poob mus rau hauv qab 80V nyob rau hauv 30 vib nas this tom qab lub ceev shutdown pib. Circuit Court nyob rau hauv 1 ko taw (305 mm) los ntawm PV module array yuav tsum poob mus rau hauv qab 80V nyob rau hauv 30 vib nas this tom qab lub ceev ceev pib.
Cov tivthaiv-theem hluav taws kub ceev kaw qhov system muaj tsis siv neeg lub hwj chim tawm thiab rov qab ua haujlwm. Raws li lub hauv paus ntawm kev ua kom tau raws li qhov xav tau ntawm kev kaw nrawm nrawm ntawm NEC2017 & NEC2020 690.12, nws tuaj yeem ua kom lub zog tsim hluav taws xob ntau tshaj plaws ntawm lub tshuab hluav taws xob photovoltaic thiab txhim kho lub zog tsim hluav taws xob. Thaum lub zog tseem ceeb yog qhov qub thiab tsis muaj qhov xav tau thaum muaj xwm txheej ceev, lub module theem ceev kaw PLC tswj lub thawv yuav xa cov lus txib kaw mus rau lub kaw lus ceev ceev los ntawm cov kab hluav taws xob photovoltaic txuas rau txhua lub vaj huam sib luag photovoltaic; Thaum lub zog hluav taws xob raug txiav tawm lossis pib nres thaum muaj xwm txheej ceev, cov khoom siv-theem ceev ceev PLC tswj lub thawv yuav xa cov lus txib txuas mus rau lub kaw lus ceev ceev los ntawm cov kab hluav taws xob photovoltaic kom txiav tawm txhua lub vaj huam sib luag photovoltaic.
