溫度漂移：環(huán)境溫度的改動(dòng)影響元器材的參數(shù)的改動(dòng)，然后致使穩(wěn)壓器輸出電壓改動(dòng)。常用溫度系數(shù)標(biāo)明溫度漂移的大小。
必定溫度系數(shù)：溫度改動(dòng)1攝氏度致使輸出電壓值的改動(dòng)△UoT，單位是V/℃或毫伏每攝氏度。
相對(duì)溫度系數(shù)：溫度改動(dòng)1攝氏度致使輸出電壓相對(duì)改動(dòng)△UoT/Uo，單位是V/℃。
靜電噪聲。指在額外輸入條件下，外加到電源框體的任意有些時(shí)，全輸出電路能堅(jiān)持正常工作情況的一種重復(fù)脈沖狀的靜電。通常保證5——10KV以內(nèi)。
電源構(gòu)造的安全懇求。
空間懇求。UL、CSA、VDE安全標(biāo)準(zhǔn)側(cè)重了在帶電有些之間和帶電有些與非帶電金屬有些之間的表面、空間的距離懇求。 UL、CSA懇求：極間電壓大于等于250VAC的高壓導(dǎo)體之間，以及高壓導(dǎo)體與非帶電金屬有些之間（這兒不包括導(dǎo)線間），不管在表面間仍是在空間，均應(yīng)有0.1英寸的距離；VDE懇求交流線之間有3mm的徐變或2mm的凈空位；IEC懇求：交流線間有3mm的凈空空地及在交流線與接地導(dǎo)體間的4mm的凈空空地。其他，VDE、IEC懇求在電源的輸出和輸入之間，至少有8mm的空間距離。
