We will have 6 days holiday from 1st-6th Oct 2020(GMT+8) for the Mid-autumn Festival and Chinese National Holiday. Orders after 30th Sep will proceed on 7th Oct.

Non-invasive AC Current Sensor-100A

-15% Non-invasive AC Current Sensor-100A
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.
