ACTIVE CURRENT TRANSFORMER WDI SERIES

AC/DC Direct-Imaging Current Transformers (Open-Loop Converters) Description Direct-imaging current transformer (Open-Loop Converter) The WDI current sensor is a direct-imaging current transformer designed for measuring DC and AC currents. The primary current flow generates a magnetic flux, which is evaluated in the air gap by means of a magnetic circuit and Hall sensor. An electronic circuit processes the signal from the Hall sensor and outputs an exact image of the primary current with a voltage at the output. Advantages (Electrical) Measurement of DC and AC currents Voltage output low power consumption no additional losses in the measuring circuit high-quality insulation materials listed according to UL safe, electrically isolated primary and secondary circuits good value for money Advantages (Mechanical) low weight robust housing designs (horizontal/vertical mounting) Connections: terminals, plugs, flat connectors or cables versatile range of housings with different push-through openings Typical applications Industry, renewable energies, railway technology, energy, automation and building technology Technical data Type 25 150 300 Primary current [A] ÎPN Peak 25 150 300 Max.
