Fua Fa'atekinisi
1. Vaega e tasi AC fa'aoga
Vaita'i va'aiga: 100V, 220V, 380V, ma isi.
Va'aiga o iai nei:5A, 50a, ma isi;O le fa'ata'ita'iga o le transformer tatala i fafo o le taimi nei e filifili.
Gaioiina o faailoilo:ua fa'aaogaina masini mita fa'apitoa, ma ua fa'aaogaina le 24 bit AD.
Ova le uta gafatia:1.2 taimi ole tele e mafai ona gafatia;O le vave (<20ms) o loʻo i ai nei e 5 taimi, o le voltage e 1.2 taimi, ma e le faʻaleagaina le laina.
Fa'alavelave fa'aofi:alavai eletise >1k Ω /v.
2. Feso'ota'iga feso'ota'iga
Ituaiga fa'aoga:1-ala RS-485 fesoʻotaʻiga fesoʻotaʻiga.
Feso'ota'iga feso'ota'iga:MODBUS-RTU protocol.
Fa'asologa o fa'amaumauga:polokalama e mafai ona seti "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
Feso'otaiga:e mafai ona seti le paud rate o le RS-485 fesoʻotaʻiga i le 9600, 19200, 38400bps;Ole fua ole baud e fa'aletonu ile 9600bps.
3. Su'ega fa'amaumauga o mea na maua
Voltage, taimi nei, malosi, malosi eletise ma isi mea eletise.
4. Sa'o le fua
Voltage, taimi nei ma le malosi:± 1.0%;Active kwh ole la'asaga 1.
5. Tu'ueseese eletise
RS-485 fa'afeso'ota'i e tu'u'ese'ese mai le tu'uina atu o le mana AC, fa'aulu eletise ma fa'aoga o lo'o iai nei;Tu'u'ese fa'asagatau voltage 2000vac.
6. Sapalai eletise
Faiga sapalai eletise:ole laina eletise ole ac85~265
