Beckhoff’s SCT5564 universal ring-type current transformer meets EN/IEC 62020-1 standard.

Beckhoff introduced its SCT5564, a ring-type current transformer that offers a universal current-sensitive measurement system for AC and DC differential currents in conformance with the EN/IEC 62020-1 standard. The differential current transformer (type B/B+) can be used as a residual current monitor (RCM) and can measure DC and AC residual currents with up to 100 kHz frequency in the 0 to 2 A range. The transformer has an analog 4…20mA output that represents the real-time RMS value (TRMS) of the measured differential current. In addition, a potential-free relay output (NO/NC) with freely selectable residual current can be used for warning purposes or system shutdown if the TRMS value exceeds the preset value.
