Description

The Magnelab SCT-1250 series is one of the most popular and frequently used split core current sensing transformers on the market. It is designed to transform up to 800 amperes of AC input current into a 0.333 volt output. This type of AC current sensors is used in existing electrical wiring installations. This is because they can simply and safely be snapped around the conductor that is already installed. The SCT-1250 series comes with a self locking mechanism for added safety. It is most commonly used in recording, data logging, energy management, power monitoring and cost allocation.

As a split core current transformer manufacturer, Magnelab has created a number of other transformers, including the SCT-075H split core current transformer, which is similar to the SCT-1250 but has a rated current of only up to 200 amperes. Each is unique and has its own features, however. As such, the SCT-1250 has a maximum of 800 Amps rated input and a 0.333 Volt output. Its linearity accuracy is impressive at 1% either way and this accuracy is at 10 percent to 130 percent of the rated current. The phase angle is less than 2 degrees. It operates within the frequency range of 50 Hz and 400 Hz. It comes with a twisted pair lead measuring 8 foot in length. On a bare conductor, its maximum voltage is 600 volts. The device is also fully UL recognized, as well as being compliant with both CE and RoHS standards. Finally, it also comes with a 10 year warranty as standard to guarantee its quality.
