Adadin da sauran sigogin lantarki a cikin hanyar sadarwa ta AC mai hawa uku tare da ƙimar mitar 50Hz ko 60Hz.Na'urar aunawa tana sanye take da hanyar sadarwa ta RS485 mai lamba 1 (na zaɓi), 1-way TTL interface da tsarin sadarwa na MODBUS-RTU, wanda ya dace don haɗawa da kwamfutoci masu guntu iri-iri.Yana da halayen aminci mai kyau, ƙananan ƙananan, nauyin haske, kyakkyawan bayyanar, shigarwa mai dacewa da sauransu.
1. Single lokaci AC shigarwa
1) Wutar lantarki:3 * 220 / 380v uku-lokaci hudu tsarin waya.
2) Kewayon yanzu:5A, 50a, 150A, 250A da sauran zaɓuɓɓuka;Samfurin na'urar budewa ta waje na yanzu zaɓi ne.
3) sarrafa sigina:An karɓi guntu na musamman, kuma an karɓi 24 bit AD.
4) Ƙarfin lodi:1.2 sau kewayon yana da dorewa;A halin yanzu (<200ms) na yanzu shine sau 5, ƙarfin lantarki shine sau 1.2, kuma kewayon bai lalace ba.
5) Rashin shigar da bayanai:tashar wutar lantarki> 1k Ω / v, tashar ta yanzu ≤ 100m Ω.
2. Sadarwar sadarwa
1) Nau'in Interface:1-hanya RS-485 sadarwa dubawa, 1-hanyar TTL dubawa.
2) Ka'idar sadarwa:MODBUS-RTU yarjejeniya.
3) Tsarin bayanai:software na iya saita "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
4) Yawan sadarwa:Za a iya saita ƙimar baud na nesa na RS-485 sadarwa a 1200, 2400, 4800, 9600bps;Matsakaicin adadin baud na cibiyar sadarwar gida ta RS-485 an daidaita shi a 9600bps, "n, 8,1" tsari.
5) Bayanan sadarwa:wutar lantarki, halin yanzu, wuta, wutar lantarki da sauran sigogin lantarki.
3. daidaiton aunawa
Voltage, halin yanzu da iko:± 1.0%;kwh mai aiki shine matakin 1.
4. Keɓewar lantarki
Ware haɗin do/rs-485 daga wutar lantarki na DC, shigar da wutar lantarki da shigarwar yanzu;Warewa juriya irin ƙarfin lantarki 2000vac.
5. Wutar lantarki
2) Lokacin da aka ba da wutar lantarki dc3.3v, ƙarfin ƙarfin ƙarfin ba zai wuce 3.5V ba, kuma yawan wutar lantarki: ≤ 2W.
3) Lokacin da aka ba da wutar lantarki dc5-24v, ƙarfin ƙarfin ƙarfin ba zai wuce 25V ba;Yawan wutar lantarki: ≤ 2W.
