Large Wireless Current Transducer SCT-200W by Magnelab

Product Description

Magnelab’s Large Wireless Current Transducer, the SCT-200W split-core current sensors transform an AC input current up to 800 Amps to an output of 0.333V RMS or 1.0V RMS. Split-core transformers are ideal for installation on existing electrical wiring by snapping around the conductor. The SCT series have a self-locking mechanism.

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 5A.

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.

If you’re interested in a wireless product that has a smaller opening and can measure lower amperages, see the SCT-125W.

The controller can be DIN rail mounted.
