Izilawuli zamandla zochungechunge lwe-GS40aklanyelwe ukuhlukanisa amandla kagesi nokumelanakanye ne-inductiveimithwalo, njengamahhavini, iziko,ama-transformer,ama-heat sealer, njll. Izilawuli ziqukethe ama-semi-conductors wamandla (SCRs), osinki osayizi ofanele wokushisa, i-trigger circuit.Isilawuli samandla samukela okukhiphayo okungu-4 kuya ku-20 mA dc kusuka kusilawuli sezinga lokushisa noma singahlinzekwa ngenketho eyenziwa ngesandla kusetshenziswa i- potentiometer ekude.
Izilawuli ze-GS40 Series zinikeza izindlela ezimbili zokulawula ngokulinganayo: I-Zero crossing switched kanye ne-Phase angled exoshiwe.
Ngemodi eshintshiwe ye-Zero crossing, isilawuli sishintsha imijikelezo ephelele yevolthi ye-ac.I-trigger circuit idizayinelwe ukuvula ama-SCR ngokuseduze ngangokunokwenzeka endaweni lapho igagasi le-AC sine linqamula ku-zero.Empeleni, i-voltage yolayini ivuliwe futhi ivaliwe futhi isetshenziswe kuma-heater emijikelezweni yonke.Ngokufaka okungu-4 kuya ku-20 mA, okukhiphayo kuzocishwa ngaphansi kuka-4 mA futhi kugcwale ku-20 mA.
Isenzo sokulinganisa sitholwa ngokushintsha inani lemijikelezo enanini lemijikelezo evaliwe.Okukhiphayo kuzohluka ukusuka kumjikelezo owodwa kuye phambili kanye nemijikelezo eyisishiyagalolunye yephulwe ekufakweni okuphansi, kuye kuyo yonke imijikelezo ekufakweni okuphezulu.Lokhu okukhiphayo kuhlanganiswe ama-heaters akhiqiza ukushisa okulingana ngokushelelayo okuhluka ngokuqondile nesignali yokufaka.Kule modi yokulawula, i-waveform ye-voltage ephumayo iyigagasi le-sine elihlanzekile, ngakho-ke akudingeki ukhathazeke ngesizukulwane se-harmonic.
Ngemodi yokudubula i-engeli yeSigaba, amandla omthwalo alawulwa ngokulawula indawo yokuvula (ukudubula) yomjikelezo ngamunye wesigamu we-AC sine wave egcwele.Kule modi yokulawula, i-waveform ye-voltage ephumayo ayiyona into ehlanzekile. i-sine wave, enokufakwa kwesignali engu-4-20mA, i-voltage chopper ephumayo, izokhiqiza inani elithile lama-harmonics, lapho ukukhishwa kwamandla okugcwele, okukhiphayo kuzoba yi-sine wave.
Izici zeIzilawuli zamandla ze-GS40 scrnjengoba ngezansi:
1.I-microcontroller eyakhelwe ngaphakathi yokusebenza okuphezulu.
2.Low ukusetshenziswa kwamandla design.
3.I-Wide main voltage input(AC110–440V).
4.Umklamo ohlangene, ubukhulu obuncane.
5.Sekela okokufaka kwe-analogue engu-4-20mA,0-10v.
I-6.Ukuvikela okuphelele: Isigaba silahlekelwa, sishisa kakhulu, sidlula, silahlekelwa umthwalo.
7.Ukuxhumana kwe-Modbus.
