- 產品詳情
WRV系列轉換器采用了原始設計，具備高頻脈沖寬度調制(PWM)電流模式調節器，能夠支持極寬的輸入電壓范圍。這種設計使得WRV系列特別適合于非穩壓電源應用，例如電池和太陽能電池等，同時也適用于需要多種電源輸入的系統。由于不需要預調節器，這種設計不僅簡化了系統結構，還降低了成本。此外，WRV系列能夠實現嚴格的輸出電壓調節，并提供非常低的無脈沖紋波，溫度系數(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，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系列轉換器在多種電源環境中都能提供穩定可靠的電力轉換解決方案。
