G. Von VOLTAGE SETTINGS

Von Voltage指(zhi)負載(zai)開(kai)始吸(xi)(xi)(xi)取電(dian)流時的(de)電(dian)壓。Von Voltage共有兩種操作模式：Von Latched 開(kai) 及 Von Latched 關 。當(dang)Von Latched開(kai)，當(dang)電(dian)壓值(zhi)達(da)到(dao)Von電(dian)壓時，負載(zai)開(kai)始吸(xi)(xi)(xi)入(ru)電(dian)流，且電(dian)壓低(di)于(yu)Von電(dian)壓時，仍然持續吸(xi)(xi)(xi)入(ru)電(dian)流。Von Latched 關，電(dian)壓值(zhi)達(da)到(dao)Von電(dian)壓時，開(kai)始吸(xi)(xi)(xi)入(ru)電(dian)流，但當(dang)電(dian)壓值(zhi)低(di)于(yu)Von電(dian)壓時，停(ting)止吸(xi)(xi)(xi)入(ru)電(dian)流。如圖：Von Latched被設置為關閉時，若Von-Voltage限(xian)(xian)制已超過，負載(zai)模塊將開(kai)始吸(xi)(xi)(xi)入(ru)電(dian)流，直至輸出電(dian)壓下(xia)降于(yu)Von-Voltage限(xian)(xian)制時，才會停(ting)止吸(xi)(xi)(xi)收電(dian)流。
