W750DC系列SCR直流控制器
一 產(chǎn)品特點
1.單一規(guī)格設計，主電源於200-480VAC範圍內(nèi)皆可使用。
2.無電源相序接線的問題。
3.具多重異常指示及檢出功能(欠相、過電流、過熱、過電壓、零電壓…等)。
4.內(nèi)建隔離式電壓迴授。
5.控制訊號端子臺，採用歐式可分離式端子臺，更換時控制迴路可免重新配線。
二 DC4Q控制原理
1.本控制利用SCR閥流體組成的橋式整流器，兩組作逆向並聯(lián)。
2.當SCR1導通時，控制器正輸出，即A為正，H為負，電壓、電流為正，工作於第一象限。
3.當SCR1截止SCR2導通時，控制器會先將負載上之剩餘能量釋放回電源側(cè)(回生放電)，此時A為正、H為負，電壓為正，電流為負，工作於第四象限。
4.當剩餘能量釋放完畢時，控制器負輸出，此時A為負、H為正，電壓、電流為負，工作於第三象限，依此類推即為第四象限控制原理。
