詳細(xì)介紹
力士樂比放大器內(nèi)部全部采用貼片工藝生產(chǎn),進(jìn)口元器件,增強(qiáng)了抗干擾性能;集成度高,體積小巧,結(jié)構(gòu)緊湊,除了調(diào)節(jié)元件,其它均不外露,避免金屬件脫落造成短路;內(nèi)部采用特殊功率器件、優(yōu)化的電路設(shè)計(jì),溫升低,摒棄了笨重的散熱片;標(biāo)準(zhǔn)導(dǎo)軌放大器為標(biāo)準(zhǔn)導(dǎo)軌安裝式,用于驅(qū)動(dòng)兩個(gè)電磁鐵比例閥。放大器對(duì)電磁比例閥提供所需電流以校準(zhǔn)閥的調(diào)整量,使之與輸入信號(hào)相對(duì)應(yīng)。該放大器用于開環(huán)控制系統(tǒng)。放大器通過對(duì)電磁鐵提供一切換電流,使閥的調(diào)整與輸入信號(hào)(電壓或電流)成比例。為保證閥的調(diào)整精度,可用放大器上的電位器調(diào)整增益和偏流。供給放大器的輸入信號(hào)通常是由外界電位器或PLC控制單元提供。放大器由斜坡發(fā)生器、偏流調(diào)整、增益調(diào)整、PWM調(diào)制、使能控制以及保護(hù)電路組成,電流調(diào)節(jié)范圍0-3安,負(fù)載阻抗2-45Ω。安裝,拆裝方便;
