The MCT-0024 by Magnelab was previously sold under the name MAG-J24M420. The device is a split core current sensor with a 24mm opening. It is able to transform up to 250 Amps of AC current input into an output of between 4 and 20 mA DC current. As a current transformer with 4-20 ma output, it is the perfect device for converting AC current to DC current, usually for measuring or monitoring purposes. The device comes with a self-locking mechanism. This means that it can easily, and most of all safely, snap around an existing conductor and get to work.
The device is frequently used as a power monitor for pumps and HVAC systems, but also in refrigeration. In fact, it is regularly used in small industrial motors. It also has suitable applications for lighting and fans.
The device has a rated input of 250 Amp and a standard 4 to 20 mA DC output. One of the things that makes this device so powerful is that, like the MCT-0016 AC current sensor, it has an accuracy of 2% either up and down, and that the ripple is 2% of the output voltage. At continuous usage, its maximum allowable current is 120% of the rated value. For a duration of one minute, the maximum allowable current is 150% of rated. The frequency range for the device is between 50 and 60 Hz. It comes with two M3 screw terminals and follows installation category CAT III. The MCT-0024is UL recognized and compliant with RoHS and CE. It also comes with a 10 year warranty.
