C漏电传感COB (Ior-COB)

C漏电传感COB(Ior-COB)主要用于防止漏电断路模块因电容漏电流(Ioc)而动作。

· Low Power Consumption (Pd=5mW, 220V)
· Input High Frequency Noise Filter
· Internal Blanking Circuit
· High Gain Differential Amplifier
· Minimum 100㎂ Output Current to Trigger SCR
· Extremely Minimized External Part Counts
· Built-in thyristor ( MCR100-8 )
· High noise immunity, Large surge margin
· 5P HIC package by FR4

阻性漏电流 [Ior] : 因线路接地故障而引起的漏电流
电容漏电流 [Ioc] : 即使无线路接地故障,也通过对地电容(自电容)始终流过的漏电流
合成漏电流 [Io] : Ior + Ioc 的求和电流

现有的漏电断路器由复合漏电流[Io]值动作(工作),因此,最近通过LED灯/计算机电源/逆变器等流过的Ioc导致断路器自动断路(切断)的现象经常发生。

从设计结构上,C漏电传感COB(Ior-COB)不得在低于3倍的Ioc电流环境中动作(工作),无自动脱扣现象。

C漏电传感COB (Ior-COB)工作电流 : Ior = 25mA / Ioc = 3 X Ior = 75mA
