電壓失壓計(jì)時(shí)器/計(jì)時(shí)儀  CD36-JSY-3B/BS 

計(jì)時(shí)范圍:D01h-9999h（小時(shí)）
計(jì)時(shí)誤差:≤s/24h(小時(shí)）
CT二次側(cè)回路阻抗:≤O.01Ω
5A 3x100V的
整機(jī)功耗:≤3,5VA
動(dòng)作電壓:當(dāng)PT任意一相電壓低于78±2V時(shí),則該相失壓并計(jì)時(shí),當(dāng)PT任意一相電壓返回到的85±2V以上時(shí),則該相恢復(fù)正常。
動(dòng)作電流:當(dāng)PT某一相失壓且接入儀器的CT電流大于25mA±5mA時(shí),儀器該相計(jì)數(shù)器開始計(jì)時(shí)并報(bào)警
