纳米晶高矩形比漏电流互感器磁芯 Nanocrystalline High Rectangular Ratio Leakage Current Transformer Cores

钴基非晶高矩形比磁传感器磁芯具有中低饱和磁感应强度（钴基非晶0.58T, 铁基纳米晶1.2T)。低矫顽力，低耗损，出色的抗磨损和耐腐蚀能力，对温度依赖性低。具有非常高的矩形比，在很小的电流下就可以达到饱和，可用于漏电保护。

Fe-based Nanocrystalline & Co-based Amorphous High Rectangular Ratio Magnetic Cores possess a mid and low saturation magnetic induction(Co-based Amorphous 0.58T; Fe-based Nanocrystalline 1.2T), low coercivity, low loss, excellent wear and corrosion resistance, low dependence on temperature

经典应用 Typical Application:

磁放大器

Magnetic Amplifier(MagAmp)

漏电流互感器

Leakage Current Transformer

磁传感器

Magnetic Sensor

尖峰抑制器

Spike Suppressor
