Ipharamitha yezobuchwepheshe
1. Okokufaka kwe-AC kwesigaba esisodwa
Ibanga lamandla kagesi: 100V, 220V, 380V, njll.
Ibanga lamanje:5A, 50a, njll;Imodeli ye-transformer yamanje yokuvula yangaphandle iyakhethwa.
Ukucutshungulwa kwesignali:I-chip ye-metering ekhethekile iyamukelwa, futhi i-24 bit AD yamukelwa.
Umthamo wokulayisha ngokweqile:1.2 izikhathi ububanzi busimama;I-current (<20ms) yamanje izikhathi ezingu-5, i-voltage iyizikhathi ezingu-1.2, futhi ububanzi awonakali.
I-impedance yokokufaka:isiteshi sikagesi >1k Ω /v.
2. Isixhumi esibonakalayo sokuxhumana
Uhlobo lwesixhumi esibonakalayo:1-indlela RS-485 ukuxhumana esibonakalayo.
Iphrothokholi yokuxhumana:Iphrothokholi ye-MODBUS-RTU.
Ifomethi yedatha:isofthiwe ingasetha okuthi "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
Izinga lokuxhumana:izinga le-baud lokuxhumana kwe-RS-485 lingasethwa ku-9600, 19200, 38400bps;Izinga le-baud lizenzakalelayo libe ngu-9600bps.
3. Hlola idatha yokuphumayo
I-voltage, yamanje, amandla, amandla kagesi kanye nezinye imingcele kagesi.
4. Ukunemba kokulinganisa
I-Voltage, yamanje namandla:± 1.0%;I-kwh esebenzayo ileveli 1.
5. Ukuhlukaniswa kukagesi
Isixhumi esibonakalayo se-RS-485 sihlukanisiwe nokunikezwa kwamandla e-AC, okokufaka kagesi kanye nokokufaka kwamanje;Isolation ukumelana ne-voltage 2000vac.
6. Ukunikezwa kwamandla
Imodi yokunikeza amandla:ububanzi be-voltage yi-ac85 ~ 265
Ukusetshenziswa kwamandla okujwayelekile:≤ 1W.
7. Indawo yokusebenza
Izinga lokushisa lokusebenza: -20~+70 ℃;Izinga lokushisa lesitoreji: -40~+85 ℃.
Umswakama ohlobene:5~95%, akukho ukufingqa (ku-40 ℃).
Ukuphakama:0 ~ 3000 amamitha.
Imvelo:indawo engenakho ukuqhuma, igesi ebolayo kanye nothuli olubambayo, futhi ngaphandle kokuzamazama okubalulekile, ukudlidliza nomthelela.
8. Ukwehla kwezinga lokushisa:≤100ppm/℃.
9. Usayizi womkhiqizo:90mm*40mm.
