- 產(chǎn)品詳情
WRV系列轉(zhuǎn)換器采用了原始設(shè)計(jì)，具備高頻脈沖寬度調(diào)制(PWM)電流模式調(diào)節(jié)器，能夠支持極寬的輸入電壓范圍。這種設(shè)計(jì)使得WRV系列特別適合于非穩(wěn)壓電源應(yīng)用，例如電池和太陽(yáng)能電池等，同時(shí)也適用于需要多種電源輸入的系統(tǒng)。由于不需要預(yù)調(diào)節(jié)器，這種設(shè)計(jì)不僅簡(jiǎn)化了系統(tǒng)結(jié)構(gòu)，還降低了成本。此外，WRV系列能夠?qū)崿F(xiàn)嚴(yán)格的輸出電壓調(diào)節(jié)，并提供非常低的無(wú)脈沖紋波，溫度系數(shù)(TC)低于50 ppm/°C。
WRV系列提供三種輸出電壓范圍：0至2kV、2.5kV或3kV。同時(shí)，它支持三種輸入電壓范圍：3.6至10Vdc、6至15Vdc以及1.5至26Vdc，輸出功率為1W。這些特性使得WRV系列轉(zhuǎn)換器在多種電源環(huán)境中都能提供穩(wěn)定可靠的電力轉(zhuǎn)換解決方案。
