2. Key Features & Ayyuka
1. Mai Sarrafa Mai Kula da Ayyuka
EGC tana haɗa cikakken mai sarrafa filin yanzu mai aiki don yanayin sarrafa hannu, mai ikon ɗaukar sarrafa tsarin idan babban mai sarrafawa ya gaza. Wannan mai sarrafa yana da ƙirƙirar saiti mai zaman kanta, sayan martani, da ƙarfin fitarwar bugun jini, yana tabbatar da ingantaccen tsarin aiki yayin gaggawa.
2. Sashin Kula da Ƙofa mai zaman kansa
Ba kamar naúrar sarrafa ƙofa a cikin COB ba, EGC tana goyan bayan kewayon mitar mai faɗi, wanda ya dace da tsarin wutar lantarki daban-daban kamar 16⅔ Hz, 50 Hz, da 60 Hz. Wannan sassauci yana ba da damar yin amfani da tsarin UNITROL 5000 a cikin samar da wutar lantarki da sauran aikace-aikacen mitar masana'antu na musamman.
3. Ayyukan Kariya da Kulawa
ECG yana haɗa ayyukan kariya da yawa, gami da:
Kariya na Juyin Juya Lokaci, mai bin ANSI 51.
Kariya ta wuce gona da iri, mai bin ANSI 50.
Gano Gajerun Da'irar DC da Iyakanta.

Ƙirƙirar sarkar bugun bugun jini mai girma.
Waɗannan ayyuka suna tabbatar da tsarin zai iya amsawa da sauri zuwa ga kurakurai masu mahimmanci ko da a yanayin ajiya.
4. Samar da wutar lantarki mai zaman kanta
Ana amfani da EGC ta hanyar tushen VDC 24 mai zaman kanta, daban da tsarin wutar lantarki na COB ko MUB. Wannan yana ƙara haɓaka rayuwar sa da 'yancin kai na aiki yayin babban gazawar tsarin.
3. Ƙa'idar Aiki & Haɗin Tsarin
1. Sarrafa Tsarin Gine-gine
A matsayin madadin ga COB, EGC yana fasalta kayan masarufi masu zaman kansu da ƙirar software. Yana haɗi zuwa na'urori kamar COB da MUB ta igiyoyin ribbon, karɓar siginar matsayi daga babban tsarin. Yana iya canzawa ta atomatik ko da hannu zuwa yanayin ajiya akan gano babban gazawar tsarin.
2. Ka'idodin Aiki na Regulator
A cikin yanayin ajiya, mai sarrafa EGC na yanzu yana ɗaukar tsarin sarrafawa Proportal-Integral (PI). Za a iya daidaita ribar daidaitattun sa (KCR) da na yau da kullun (TCR) a matakai da yawa ta hanyar sauya kayan aiki. Masu amfani za su iya zaɓar sigogin da suka dace dangane da ainihin halayen tsarin (misali, tsayin lokaci na jujjuyawar filin, halayen kaya) don tabbatar da ingantaccen tsarin aiki.
3. Fitar Pulse Generation
Babban injin bugun bugun jini na EGC na ciki yana samar da sarkar bugun bugun jini mai karfin 62 kHz. Waɗannan nau'ikan bugun jini ana keɓe su kuma ana aika su zuwa GDI don haɓaka ƙarfi, a ƙarshe suna tuƙi gadar thyristor. Kewayon sarrafa lokaci mai faɗin bugun jini yana goyan bayan yanayin aiki mai gyarawa da inverter, yana mai da shi dacewa da tsarin aiki huɗu huɗu.
4. Dabarun Kariya da Aiki
Ayyukan kariya na EGC sun kasance masu zaman kansu gaba ɗaya daga COB. Kariyar ta da ta wuce kima ta kasu kashi biyu:
Ana iya saita ayyukan kariya don ƙararrawa ko tafiya da fasalin daidaitacce jinkirin lokaci don hana lalacewa.
