Feature
1. PP Box-type, qhuav resin infusion;
2. Cov txiv ntoo tooj liab / cov ntsia hlau ua rau, cov yas npog uas muaj rwb thaiv tsev, kev teeb tsa yooj yim;
3. Muaj peev xwm loj, me me;
4. Kev tiv thaiv rau qhov hluav taws xob siab, nrog rau kev kho tus kheej;
5. Tam sim no muaj zog heev, muaj peev xwm tiv taus dv / dt siab.
Ib yam li lwm cov khoom CRE, cov koob capacitor muaj daim ntawv pov thawj UL thiab 100% hlawv-hauv kev sim.
Daim Ntawv Thov
1. Siv dav hauv DC-Link circuit rau kev lim dej cia zog;
2. Hloov tau cov electrolytic capacitors, ua tau zoo dua thiab siv tau ntev dua.
3. Pv inverter, cua fais fab converter; Txhua yam ntawm zaus converter thiab inverter fais fab mov; Tsheb fais fab ntshiab thiab hybrid; SVG, SVC cov khoom siv thiab lwm yam kev tswj hwm lub zog zoo.

Daim duab qhia txog
Qhov kev thov kom txuag hluav taws xob thiab cov khoom siv rov ua dua tshiab txhawb kom muaj kev tsim cov khoom xws li tsheb fais fab, PV converters, thiab cov tshuab hluav taws xob cua. Cov khoom no xav tau DC rau AC inverter kom ua tiav lub operating system. Cov lim dej thiab DC-link capacitors yog cov khoom tseem ceeb rau lub zog fais fab uas muab kev txhawb nqa rau qhov xav tau ntawm kev nce zog nrog cov hluav taws xob siab thiab cov dej ntws ripple.
Ua ib lub tuam txhab thev naus laus zis tshiab, CRE muaj pab pawg R&D thiab tsim khoom rau cov khoom siv hluav taws xob, thiab tsim cov chaw tsim khoom siv hluav taws xob R&D nrog cov koom haum tshawb fawb nto moo thoob ntiaj teb. Txog tam sim no, CRE muaj ntau dua 40 qhov kev tsim kho tshiab thiab cov qauv siv hluav taws xob thiab koom nrog kev tsim 10 lub teb chaws thiab kev lag luam tus qauv, tau ntawv pov thawj nrog ISO-9001, IATF16949, ISO14001/45001, thiab UL. Peb mob siab rau kev tsim ntau tus khub lag luam rau kev tsav tsheb tsim kho tshiab.
Cov khoom nrov ntawm CRE:
① DC-txuas capacitor
② AC lim capacitor
③ Kev khaws cia zog / Lub zog ntim hluav taws xob
④ IGBT snubber
⑤ Lub zog rov qab los
⑥ Lub capacitor txias dej
