3 Phase CT Coil Module – 100A

It is a 3 Phase Current Transformer Module. This CT Coil can sense the current of 1 to 3 phase AC Supply. It is a non invasive CT Coil. The wire for which current measurement needs to be done should pass through any of the hole in the CT Coil. There are 3 different CT Coil in this module, so, 1 CT Coil for 1 phase. Each wire should pass through a different hole. It gives a combined output for all 3 phases’ current. The output is a analog DC voltage signal. The Voltage to Current Transfer Ratio of the CT Coil is 10:1. That is the CT Coil’s output is 1V @ 10 A current. Its also useful in measuring single phase current, by passing a single phase wire through any single hole only.

The output of the module is a analog signal, with voltage to current ratio of 10:1. It can be used with any device, by adding a voltage divider, and making the output voltage range in range of the device in which it is used.

The module has a metal casing, and has 2 holes for mounting it on any surface. It can be easily mounted on wood or panels.
