Jsy-mk-333-nhatu-chikamu chakamisikidzwa kuyerwa module itatu-chikamu chakamisikidzwa kuyerwa module ine yakasununguka yakazvimirira kodzero yepfuma yezvivakwa yakagadziridzwa nekambani yedu ichishandisa microelectronic tekinoroji uye akakura-akakura akabatanidzwa maseketi, achishandisa tekinoroji yepamusoro senge digital sampling uye kugadzirisa tekinoroji. uye SMT maitiro.Iyo tekinoroji kuita kwe detector inosangana zvizere neakakodzera tekinoroji zvinodiwa zve 0.5s matatu-chikamu anoshanda watt awa mita muIEC 62053-21 yenyika standard, uye inogona zvakananga uye nemazvo kuyera voltage, ikozvino, simba, simba chinhu, huwandu hwemagetsi, huwandu. huwandu uye mamwe ma parameter emagetsi mune matatu-chikamu AC network ine yakayerwa frequency ye50Hz kana 60Hz.Iyo metering module ine 1-nzira RS485 yekutaurirana interface (inosarudzika), 1-nzira TTL interface uye MODBUS-RTU yekutaurirana protocol, iri nyore kubatanidza nemakomputa akasiyana-siyana.Iine hunhu hwekuvimbika kwakanaka, saizi diki, huremu huremu, kutaridzika kwakanaka, kuisirwa kuri nyore uye zvichingodaro.
1. Single phase AC input
1) Voltage range:3 * 220/380v matatu-chikamu mana waya hurongwa.
2) Nzvimbo yezvino:5A, 50a, 150A, 250A uye dzimwe sarudzo;Muenzaniso wekuvhura kwekunze ikozvino transformer inosarudzika.
3) Signal processing:yakakosha metering chip inogamuchirwa, uye 24 bit AD inogamuchirwa.
4) Kuwanda kwehuwandu:1.2 nguva huwandu hwakasimba;Pakarepo (<200ms) ikozvino inguva 5, voltage ndeye 1.2 nguva, uye huwandu hahuna kukuvara.
5) Input impedance:voltage chiteshi> 1k Ω /v, ikozvino chiteshi ≤ 100m Ω.
2. Kukurukurirana interface
1) Interface mhando:1-nzira RS-485 yekutaurirana interface, 1-nzira TTL interface.
2) Kukurukurirana protocol:MODBUS-RTU protocol.
3) Data format:software inogona kuseta "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
4) Kukurukurirana mwero:iyo baud rate yekure kure RS-485 yekutaurirana interface inogona kuiswa pa1200, 2400, 4800, 9600bps;Iyo baud rate yemunharaunda RS-485 yekutaurirana interface inogadziriswa pa9600bps, "n, 8,1" fomati.
5) Kukurukurirana data:voltage, ikozvino, simba, simba remagetsi uye mamwe magetsi parameters.
3. Kuyera kurongeka
Voltage, ikozvino uye simba:± 1.0%;Active kwh idanho 1.
4. Kuparadzaniswa kwemagetsi
Isolate iyo do/rs-485 interface kubva kuDC magetsi emagetsi, voltage kupinza uye ikozvino kupinza;Isolation inomira voltage 2000vac.
5. Simba rekupa
2) Kana dc3.3v simba rinopihwa, iyo peak voltage haingapfuuri 3.5V, uye yakajairika simba rekushandisa: ≤ 2W.
3) Kana dc5-24v simba rinopihwa, iyo peak voltage haifaniri kudarika 25V;Yakajairika simba rekushandisa: ≤ 2W.
6. Nzvimbo yekushanda
1) Kushanda tembiricha:-20~+70 ℃;Kuchengetedza tembiricha: -40~+85 ℃.
2) Hunyoro hunyoro:5 ~ 95%, hapana condensation (pa40 ℃).
3) Altitude:0 ~ 3000 mamita.
4) Zvakatipoteredza:inzvimbo isina kuputika, gasi rinoparadza uye guruva rinoita, uye pasina kuzunguzika kwakanyanya, kuzunguzika uye kukanganisa.
7. Tembiricha inodonha:≤100ppm/℃
8. Kuisa nzira:Embedded installation
9. Saizi yechigadzirwa:65*57*41mm
