AC Non-Invasive Current Sensor – 30A 交流電非侵入式電流感測器模組 SparkFun 原裝進口

Non-Invasive Current Sensor – 30A 這種非侵入式電流傳感器（也稱為“分體式電流互感器”）可以夾在電氣負載的電源線上，告訴您有多少電流通過它。它通過充當電感並響應載流導體周圍的磁場來實現這一點。通過讀取線圈產生的電流量，可以計算導體中流過多少電流。

這款特殊的電流傳感器可以測量高達30安培的負載，這非常適合構建自己的能量監測器，以降低功耗，甚至為交流負載構建過流保護器件。該傳感器沒有內置負載電阻，所以在大多數情況下，需要在輸出端放置一個電阻，將線圈的感應電流轉換為非常小的可測量電壓。

Non-Invasive Current Sensor – 30A

This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.

This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage.
