Sine wave inverter unikezelo lwamandla
1. Iimpawu eziphambili ze-sine wave inverter unikezelo lwamandla
■ Ukusebenzisa ulawulo lwe-CPU, isekethe ilula kwaye ithembekile;
■ Ukusebenzisa iteknoloji yokumodareyitha ububanzi be-SPWM pulse, igalelo liza liso lesine eligudileyo elinomoya ozinzileyo kunye nolawulo lombane, ukuhluza ingxolo kunye nokuphazamiseka okuphantsi;
■ Iswitshi ejiyiweyo eyakhelwe-ngaphakathi, ukutshintsha ngokukhawuleza phakathi kweendonga eziphambili kunye ne-inverter;
■ Uhlobo lombane olungundoqo kunye nohlobo lonikezelo olungundoqo lwebhetri:
A) Uhlobo lonikezelo lwamandla ombane: xa kukho umbane oyintloko, ikwimveliso engundoqo, kwaye itshintshela ngokuzenzekelayo kwimveliso ye-inverter xa igalelo elingundoqo lingaphumeleli;
B) Uhlobo oluphambili lonikezelo lwebhetri: Imveliso ye-inverter xa kukho amandla amakhulu, ngokuzenzekelayo xa igalelo le-DC lingaphumeleli
■ ukutshintshela kwimveliso engundoqo;
Kuvunyelwe ukunqumla i-DC kumandla ombane, kwaye utshintshe ngokuzenzekelayo kwi-bypass ehamba phambili, ngaphandle kokuchaphazela ukunikezelwa kwamandla komthwalo, kwaye kukulungele ukugcina nokutshintsha ibhetri;
■ Ukuba amandla ombane ebhetri aphezulu kakhulu okanye aphantsi kakhulu, umbane oguquliweyo uya kuyicima imveliso.Ukuba i-voltage yebhetri ibuyela kwisiqhelo, ukunikezelwa kwamandla kuya kuphuma ngokuzenzekelayo;
■ Xa umthwalo ugcwele kakhulu, unikezelo lwamandla ombane oluguquguqukayo luya kucima imveliso.Emva kwemizuzwana engama-50 yokuphelisa ukugcwala, unikezelo lwamandla luya kuphinda luqalise ngokuzenzekelayo imveliso.Lo msebenzi ulungele ngokukodwa izikhululo zonxibelelwano ezingajongwanga;
■ Umsebenzi wonxibelelwano lwenkxaso, ubonelele nge-RS232 interface (PIN2, 3, 5), sebenzisa isoftware yokubeka iliso ukuqonda imeko yokusebenza yobonelelo lwamandla ngexesha langempela;(Qaphela: Iimodeli ze500VA kolu ngcelele azinawo lo msebenzi okwangoku)
■Bonelela ngeseti ezimbini zeenodi ezomileyo zokwenziwa kwempazamo kwi-DC input fault (RS232PIN6, 7) kunye ne-AC output fault alarm (RS232PIN8, 9)
■ Ixhasa i-no-DC yokusebenza kwamandla, kwaye inokubaleka ngamandla amakhulu kuphela.Lo msebenzi uvumela unikezelo lwamandla ombane ukuba lusetyenziswe kuqala, emva koko ibhetri ifakwe.(Qaphela: Iimodeli ze500VA kolu ngcelele azinawo lo msebenzi okwangoku)
