480B High-precision Fais Fab Meter
♦ Txheej txheem cej luam
Yog tias txuas nrog kev sib xyaw ua ke thermal analyzer, lub ntsuas hluav taws xob muaj peev xwm muab tau cov ntaub ntawv ntau qhov hluav taws xob, tam sim no, lub zog thiab qhov kub thiab txias tib lub sijhawm rau kev tsom xam, xws li kev sib raug zoo ntawm qhov kub thiab lub zog ntawm cov khoom, cov cua kub hauv qhov sib txawv voltages. thaum ntsuas cov khoom siv cua sov, thiab lwm yam.
Dianyang Technology tau ua tiav cov haujlwm sib dhos, thiab muaj peev xwm muab 480B High-precision Power Meter thiab Dingyang DC Load Analyzer.
Tus tsim ntawm 480B tau txais kev ua haujlwm siab tshaj 32-ntsis high-speed processor thiab dual-loop 24-ntsis AD converter, nrog rau cov yam ntxwv ntawm siab precision, dav dynamic ntau yam, nrog rau cov qauv compact thiab dexterous. Nws yog ib tug tshiab-tiam kov screen digital hwj chim analyzer. Nws RS232/485, USB, Ethernet thiab lwm yam kev sib txuas tuaj yeem ua tau raws li qhov xav tau sib txawv ntawm cov neeg siv rau kev sib txuas lus.
♦ Cov cim qhia kev qhia:
| Technical ntsuas | Technical parameters |
| Bandwidth | DC: (0.5 - 1) KHz |
| Hom tswv yim | Floating input yog saws rau ob qho tib si voltage thiab tam sim no |
| Zaub hloov tshiab | Lub voj voog hloov tshiab tuaj yeem teem caij nruab nrab ntawm 0.1 thiab 5 vib nas this |
| Kab lim | Txiav tawm zaus ntawm 500Hz |
| A/D conversion | Lub sijhawm ua piv txwv yog li 70μS, 24 ntsis; ib txhij sampling ntawm voltage thiab tam sim no yog txaus siab |
| Input impedance | Qhov voltage input impedance yog hais txog 2MΩ, tam sim no input impedance yog hais txog 0.5Ω ntawm qib qis thiab txog 4MΩ ntawm qib siab. Lub input impedance ntawm lub teeb liab input davhlau ya nyob twg ntawm sab nraud sensor hloov nrog lub input voltage. Piv txwv li, thaum lub input voltage yog 10V, input impedance yog hais txog 100kΩ; thiab thaum lub input voltage yog 2V, input impedance yog hais txog 20kΩ. |
| Zero calibration method | Nws yuav calibrate rau xoom thaum twg qhov ntsuas qhov ntau hloov pauv lossis ntsuas hom hloov. |
| Kev ntsuas hom | Muaj tseeb RMS, voltage txhais tau tias, AC, DC |
| Kev siv hluav taws xob tag nrho | <10 VA |
| Ua haujlwm fais fab | AC: 100V - 240V 45-440Hz; Lub hwj chim: 100-300V DC |
| Kev sib txuas lus interface | USB (tus qauv), RS-232/485 (tus qauv), Ethernet (yeem) |
