Fiber Optic Isolation Kev Sib Txuas Lus, Ua tiav kev sib cais ntawm High & Tsawg VoltageFiber optic kev sib txuas lus txuas qhov sib txawv zaus lub hwj chim txee thiab tswj lub thawv, tag nrho cais qhov siab -voltage circuit los ntawm qis-voltage control circuit. Nws tiv thaiv kev pheej hmoo rau cov neeg ua haujlwm thiab cov cuab yeej siv los ntawm qhov muaj zog hluav taws xob nkag mus rau hauv cov chaw tswj xyuas. Cov neeg ua haujlwm tuaj yeem tswj cov khoom siv nyob deb, txhim kho kev nyab xeeb rau ntawm - qhov chaw sim.
Dav Nruam Adjustable Range, sib xws nrog ntau yam khoom kuajCov zis zaus: tsis tu ncua adjustable ntawm 30Hz mus rau 300Hz, zaus stability Tsawg dua los yog sib npaug rau 0.05%; Cov zis voltage: tsis tu ncua adjustable ntawm 0 mus rau 350V, voltage stability Tsawg dua los yog sib npaug rau 1.0%. Nws yoog raws cov khoom siv ntsuas capacitive thiab inductive kom ua tiav resonance tuning, induced withstand voltage thiab lwm yam kev xeem scenarios.
Tag Nrho -Hardware Protection for Secure TestingKev koom ua ke nrog overvoltage, overcurrent, luv-circuit, flashover, xoom-pib, choj caj npab txhaum, kev tiv thaiv hluav taws xob nkhaus, kiv cua cuam tshuam kev tiv thaiv, kev tiv thaiv theem poob thiab ntau tshaj 10 kev tiv thaiv mechanisms. Nyob rau hauv cov ntaub ntawv ntawm anomalies xws li kuaj cov khoom puas, luv luv- Circuit Court los yog overload, cov cuab yeej txiav tawm sai sai los tiv thaiv cov neeg ua haujlwm kuaj, DUT thiab tag nrho cov cuab yeej kho vajtse.
Compact Structure, Muaj zog ntawm -site AdaptabilityAdopts modular tsim thiab yuam cua txias. Cov qauv txee ruaj khov haum rau ob qho tib si kev siv hauv chav kuaj thiab kev sim mobile. Kev ywj pheej aluminium alloy tswj lub thawv nta intuitive tib neeg- tshuab interface, coarse/fine hloov hloov thiab yooj yim phau ntawv resonance tuning. Piv nrog cov txheej txheem tsim hluav taws xob ib txwm muaj, nws txhawb nqa ntawm - qhov chaw ua haujlwm tau zoo los ntawm 50%.
Khoom Qhia
Cov cuab yeej no ua raws li lub zog hluav taws xob rau kev sim ua tiav. Nws tuaj yeem sib phim nrog excitation transformers, reactors, capacitive voltage dividers thiab ib feem tso tawm detectors los tsim ib lub platform tag nrho.Siv tau Scenarios
