Kufanele Abathengi Basilungise Kanjani Isiteshi Samandla Esiphathekayo Se-5000W Sine Wave? 

Isilinganiso sokuphumayo esingu-5000W sichaza ukuthi isiteshi samandla esiphathekayo esingase sikusekele kangakanani; ayisho ukuthi umthwalo uzohamba isikhathi esingakanani. Ukucushwa kuqala ngemibuzo emibili ehlukene: ingabe isiguquli singanikezela ngesidingo esiqhubekayo nesiqalayo, futhi ingabe ibhethri lingagcina amandla anele asebenzisekayo ngesikhathi esidingekayo sokusebenza? Abathengi kufanele-ke baqinisekise i-voltage ne-frequency, i-interface ephumayo, indlela yokushaja, imikhawulo yemvelo, ukuhamba, ukuvikelwa, imibhalo kanye nobufakazi obusetshenziswa ukwamukela iyunithi eqediwe. Ukukhetha kuphela ngo-“5000W” kungakhiqiza i-inverter egcwele kakhulu noma isistimu ehlangabezana nesidingo samandla kodwa ephelelwa amandla maduzane.

Yakha iphrofayili yomthwalo olinganisiwe ngaphambi kokukhetha umthamo

Faka kuhlu zonke izisetshenziswa ezingase zisebenze kusukela esiteshini samandla futhi urekhode amandla akhona okufaka angashintshi. Hlukanisa imithwalo kanyekanye kumadivayisi angasebenzi ndawonye. Okokusebenza kwe-elekthronikhi, sebenzisa okokufaka okulinganiselwe lapho kusebenza khona kunokuba ucabangele ukuthi ilebula ichaza umsebenzi wangempela. Kumamotho, ama-compressor, amaphampu nama-transformer, qopha indlela yokuqala kanye nesidingo esiphezulu esilindelwe sesikhashana.

Iphrofayela ewumphumela idinga okungenani amanani amathathu: ama-watts aqhubekayo avamile, ama-watts amaningi ngesikhathi esisodwa kanye nesenzakalo esikhulu kunazo zonke sokuqala noma sokuhlinzwa. Ubude besikhathi bubalulekile futhi. Umthamo ongu-3 kW osebenza imizuzu eyishumi unesidingo samandla esihluke kakhulu kumthwalo ongu-1 kW osebenza amahora ayisishiyagalombili. Uma iphrojekthi inezinhlobo ezimbalwa zokusebenza, bala imodi ngayinye ngokuzimela futhi uhlonze ukulandelana okukholakala okubi kakhulu.

Abathengi abaqhathanisa ne uhla lomkhiqizo webhange lamandla aphathekayo kufanele igcine la manani enamathiselwe ku-RFQ. Umphakeli angabese ehlola uhlelo lokusebenza esikhundleni sokukhetha kulebula yokukhipha amanzi iyodwa.

Amandla, ukukhuphuka namandla yimikhawulo emithathu ehlukene
