0.333 Vac Output 1.25 inch SCT Opening The SCT-125W Split-Core 3-Phase Wireless Current Sensor series by Magnelab is a small split core wireless AC current sensor system ideal for simplifying installation on existing electrical wiring by snapping around the conductor without additional wires or connections. It transforms up to 800 amps of AC input current to a 0.333 Volt or 1.0V RMS output voltage. Each CT contains a radio frequency link powered by the measured current, which will link up with the Controller (PT Unit) for any current above 5 A. Contents include 3 AC Wireless split-core current sensors and one Controller (PT unit). The controller provides three outputs that correspond to the three remote CTs in both amplitude and phase. Typical Uses This type of device is usually used in recording, data logging, energy management, power monitoring and cost allocation. All SCT devices come with a self-locking mechanism. Additionally, it is possible to DIN Rail mount the controller. Options and General Specifications If you need a transformer that handles more amps, we also carry the SCT-200W wireless current transformer, which can handle up to 1500 amperes. The current transformer ratio of the SCT-125W takes an input current of up to 800 amperes and provides an output of 0.333 volts. Linearity accuracy is 1% either way from 10 percent to 130 percent of rated current. The phase angle at rated current is less than 1 degree. The operating and measurement frequency of the SCT-125W is 60 Hz (50 Hz upon request for Europe and other regions) with a range of 10 meters. While each wireless CT needs no external power, the controller requires 120 or 240 volts AC.
