Technical Parameter
1. Single phase AC input
Voltage range: 100V, 220V, 380V, nezvimwewo.
Nzvimbo iripo:5A, 50a, nezvimwewo;Muenzaniso wekuvhura kwekunze ikozvino transformer inosarudzika.
Signal processing:yakakosha metering chip inogamuchirwa, uye 24 bit AD inogamuchirwa.
Overload kugona:1.2 nguva huwandu hwakasimba;Pakarepo (<20ms) ikozvino inguva 5, magetsi ndeye 1.2 nguva, uye mararamiro haana kukuvara.
Input impedance:voltage chiteshi > 1k Ω / v.
2. Kukurukurirana interface
Interface type:1-nzira RS-485 kutaurirana interface.
Communication protocol:MODBUS-RTU protocol.
Data format:software inogona kuseta "n, 8,1", "E, 8,1", "O, 8,1", "n, 8,2".
Chiyero chekukurukurirana:iyo baud rate yeRS-485 yekutaurirana interface inogona kuiswa ku9600, 19200, 38400bps;Chiyero chebaud chinokanganisa kusvika ku9600bps.
3. Muedzo wakabuda data
Voltage, ikozvino, simba, simba remagetsi uye mamwe magetsi parameters.
4. Kuyera kurongeka
Voltage, ikozvino uye simba:± 1.0%;Active kwh idanho 1.
5. Kuparadzaniswa kwemagetsi
RS-485 interface yakaparadzaniswa kubva kune AC magetsi emagetsi, voltage kupinza uye ikozvino kupinza;Isolation inomira voltage 2000vac.
6. Simba rekupa
Power supply mode:voltage renji iac85 ~ 265
Mashandisiro emagetsi chaiwo:≤ 1W.
7. Nzvimbo yekushanda
Kushanda tembiricha: -20~+70 ℃;Kuchengetedza tembiricha: -40~+85 ℃.
Hunyoro hwehukama:5 ~ 95%, hapana condensation (pa40 ℃).
Altitude:0 ~ 3000 metres.
Environment:nzvimbo isina kuputika, gasi rinoparadza uye guruva rinoita, uye pasina kuzungunuswa kwakakosha, kuzunguzika uye kukanganisa.
8. Tembiricha inodonha:≤100ppm/℃.
9. Saizi yechigadzirwa:90mm*40mm.
