480B High-precision Power Meter
♦ Kakaretso
Haeba e hokahane le analyzer e kopantsoeng ea mocheso, meter ea matla a mojaro e ka fana ka lintlha tse fapaneng tsa voltage, hona joale, matla le mocheso ka nako e le 'ngoe bakeng sa tlhahlobo e felletseng, joalo ka kamano lipakeng tsa mocheso le matla a likarolo, maemo a futhumatsang tlas'a li-voltages tse fapaneng. nakong ea tlhahlobo ea lisebelisoa tsa mocheso, joalo-joalo.
Dianyang Technology e qetile mosebetsi oa ho lokisa, 'me e khona ho fana ka 480B High-precision Power Meter le Dingyang DC Load Analyzer.
Moralo oa 480B o nka processor e tsoetseng pele ea 32-bit ea lebelo le phahameng le converter ea dual-loop 24 bit AD, e nang le litšoaneleho tsa ho nepahala ho holimo, mefuta e mengata e matla, hammoho le sebopeho se kopaneng le se bonojoana. Ke sesebelisoa sa "touch screen" sa moloko o mocha oa digital power analyzer. RS232/485 ea eona, USB, Ethernet le likhokahano tse ling li ka khotsofatsa litlhoko tse fapaneng tsa basebelisi bakeng sa tlhahlobo ea puisano.
♦ Matšoao a mantlha a tekheniki:
| Lipontšo tsa tekheniki | Litekanyetso tsa tekheniki |
| Bophahamo ba motlakase | DC: (0.5 - 1) KHz |
| Mokhoa oa ho kenya | Kenyelletso e phaphametseng e amoheloa bakeng sa motlakase le hona joale |
| Hlahisa ntlafatso | Potoloho ea ntlafatso e ka beoa lipakeng tsa 0.1 le 5 metsotsoana |
| Sefa mola | Khafetsa e khaotsoeng ea 500Hz |
| Phetoho ea A/D | Nako ea sampole e ka bang 70μS, 24 bit; sampole ea nako e le 'ngoe ea motlakase le ea hona joale e tšehetsoa |
| Kenyelletso ea ho kenya | Phetoho ea ho kenya motlakase ke hoo e ka bang 2MΩ, phepelo ea hona joale ea ho kenya e ka ba 0.5Ω boemong bo tlaase le hoo e ka bang 4MΩ boemong bo phahameng. Phetoho ea ho kenya letsoho ea "terminal input" ea sensor ea kantle e fetoha ka matla a ho kenya. Ka mohlala, ha motlakase oa ho kenya e le 10V, impedance ea ho kenya e ka ba 100kΩ; 'me ha motlakase oa ho kenya e le 2V, impedance ea ho kenya e ka ba 20kΩ. |
| Mokhoa oa ho lekanya lefela | E tla lekanya ho zero neng kapa neng ha sebaka sa ho metha se fetoloa kapa mokhoa oa ho metha o fetoloa. |
| Mokhoa oa ho lekanya | RMS ea 'nete, moelelo oa motlakase, AC, DC |
| Tšebeliso ea matla ka kakaretso | <10VA |
| Phepelo ea motlakase e sebetsang | AC: 100V - 240V 45-440Hz; DC: 100V - 300V |
| Khokahano ea puisano | USB (e tloaelehileng), RS-232/485 (e tloaelehileng), Ethernet (boikhethelo) |
♦ Mekhahlelo ea ho nepahala:
