TZ2L9 Zero Phase Current Transformer 30A (25mV) - (AD53623)

Description:

This invasive current sensor (also known as a "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 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, making it ideal for building your own power monitor to keep energy usage low, or even building an overcurrent protection device for an AC load. This sensor does not have a built-in load resistor, so in most cases, a resistor will need to be placed across the output to convert the coil's induced current into a very small measurable voltage.
