美国皮尔森 PEARSON 2877 200MHZ 高精度电流探头 原装进口
产品简介：
美国皮尔逊（Pearson Electronics）1958年变开始设计和生产监测变压器 经过几十年的发展,产品广泛应用于美国军工、医疗、航空等领域,一直服役于极其复杂的瞬间信号和一些频率周期性信号环境下.奠定了它,高品质的要求。 电流测试环，国内也称电流互感器或电流传感器，电流互感器的运行情况相当于2次侧短路的变压器，忽略励磁电流，安匝数相等I1N1=I2N2 ，电流互感器一次绕组电流I1与二次绕组I2的电流比，叫实际电流比I1/I2=N2/N1=k。
Since 1955, Pearson Electronics has been manufacturing current transformer products. Our website is designed to simplify the selection of the right current probe to fit your application. Our current sensors feature pulse-current monitoring down to less than 1ns, making these high frequency current transformers ideal for a world of applications.
