16px;">（2）環(huán)境組別：屬GB6287.1-86《電子測量儀器環(huán)境試驗總綱》中的Ⅲ組儀器（即可在室外環(huán) </span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> 境使用）。</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （3）輸入電壓： AC220V ±10% </span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （4）功率：10KVA </span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （5）AC 0～2000A 無級可調(diào)、面板帶數(shù)顯電流表</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （6）輸出電壓：5V</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （7）輸出波形：輸出電流是標準正弦波，毛刺微小，優(yōu)于電力系統(tǒng)要求指標標準，紋波系數(shù)小 </span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> 于 0.3%。標準正弦波。</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （8）測量精度：（采用0.2S級材料）實際在0.1左右；各電流均可平滑平穩(wěn)連續(xù)可調(diào)，精度高</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> 于0.1級.電流電壓表顯示為真有效數(shù)值，精度高、穩(wěn)定度高。</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （9）輸出電流方式：真有效值連續(xù)可調(diào)；</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （10）電流穩(wěn)定度：0.2%</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （11）結(jié)構(gòu)形式: 一體 </span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （12）接線方式：根據(jù)要求</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> （13）保護設(shè)置：過流、過壓；</span></p><p><span style="font-family: 宋體, SimSun; font-size: 16px;"> </span></p><p
