Jsy-mk-339 magawo atatu voteji ndi wotolera wamakono ndi gawo atatu watt ola mita yokhala ndi ufulu wodziyimira pawokha waluntha lopangidwa ndi kampani yathu pogwiritsa ntchito ukadaulo wa microelectronic ndi mabwalo apadera ophatikizika akuluakulu, pogwiritsa ntchito umisiri wapamwamba kwambiri monga kusanja kwa digito ndi kukonza. teknoloji ndi ndondomeko ya SMT.Mayendedwe aukadaulo a tester amakwaniritsa zofunikira zaukadaulo wa kalasi 1 magawo atatu amphamvu a watt ola mita mu IEC 62053-21 mulingo wadziko lonse, ndipo amatha kuyeza molunjika komanso molondola voteji, panopa, mphamvu, mphamvu, kuchuluka kwa magetsi, okwana. kuchuluka ndi magawo ena amagetsi mugawo lachitatu la AC network yokhala ndi ma frequency a 50Hz kapena 60Hz.Chowunikiracho chili ndi gawo lolumikizirana la 4G, mawonekedwe olankhulirana a RS485, mawonedwe a dot matrix LCD, ndi protocol yolumikizirana ya MODBUS-RTU, yomwe ndiyosavuta kulumikizana ndi machitidwe osiyanasiyana a AMR.Zili ndi makhalidwe odalirika abwino, kukula kochepa, kulemera kwa thupi, maonekedwe okongola, kukhazikitsa kosavuta ndi zina zotero.
1. Kulowetsa kwa AC magawo atatu
1) Mphamvu yamagetsi:100V, 220V, 380V, ndi zina;
2) Mtundu wamakono:5A, 20a, 50a, 100A, 200A ndi zosankha zina;Chitsanzo cha thiransifoma wakunja wotsegulira pano ndichosankha;
3) Signal processing:chipangizo chapadera choyezera ndi 24 bit AD sampuli;
4) Kuchulukirachulukira:1.2 nthawi zosiyanasiyanazo ndizokhazikika;Nthawi za 5 za nthawi yomweyo (<200ms) zamakono ndi nthawi za 2 zamtundu wamagetsi popanda kuwonongeka;Kusokoneza kolowetsa: njira yamagetsi > 1 K Ω /v;Njira yamakono ≤ 100m Ω.
2. Kulankhulana mawonekedwe
1) Mtundu wa mawonekedwe:1-njira RS-485 kulumikizana mawonekedwe.
2) Njira yolumikizirana:MODBUS-RTU protocol.
3) Mtundu wa data:mapulogalamu akhoza kukhazikitsa "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
4) Mtengo wolumikizana:mlingo wa baud wa RS-485 kulankhulana mawonekedwe akhoza kukhazikitsidwa pa 1200, 2400, 4800, 9600bps;Mlingo wa baud umasinthidwa kukhala 9600bps.
5) Njira yolumikizirana opanda zingwe:4G, CAT1, yothandizira lte-tdd ndi lte-fdd
3. Data linanena bungwe
Voltage, panopa, mphamvu, mphamvu yamagetsi ndi zina zamagetsi.
4. Muyeso wolondola
Voltage, panopa ndi mphamvu:≤ 1.0%;Muyezo wa mphamvu yogwira ntchito 1.0
5. Mphamvu zamagetsi
Wide voteji magetsi;220VAC magetsi;Kugwiritsa ntchito mphamvu: 50mA.
6. Malo ogwirira ntchito
1) Kutentha kwa ntchito:-20 ~ + 70 ℃;Kutentha kosungira: -40 ~ +85 ℃.
2) Chinyezi chachibale:5 ~ 95%, palibe condensation (pa 40 ℃).
3) Utali:0-3000 mamita.
4) Chilengedwe:malo opanda kuphulika, mpweya wowononga ndi fumbi loyendetsa, komanso opanda kugwedezeka kwakukulu, kugwedezeka ndi kukhudzidwa.
7. Kutentha kwa mpweya
≤100ppm/℃
8. Njira yoyika
Standard 4P kalozera njanji kukhazikitsa
