Active Current Transformer Series Wdi

AC/DC Open loop current transformers

DESCRIPTION

The WDI current sensor is an open-loop current transformer designed for measuring direct and alternating currents. The primary current generates a magnetic flux and this is evaluated by means of a magnetic circuit and Hall sensor in the air gap. The signal from the Hall sensor is processed by an electronic circuit and an exact representation of the primary current is output as a voltage.

ADVANTAGES

• Measurement of direct and alternating currents
• Voltage output
• Low power consumption
• No additional losses in the measuring circuit
• High-quality UL-listed insulating materials (e.g. UL94-V0)
• Safe electrically isolated primary and secondary circuits
• Good price/performance ratio
• Low weight
• Robust housing designs (for horizontal/vertical mounting)
• Connections: clamps, plugs,
• flat-cable plugs or cables
• Wide range of housings with various push-through openings

TYPICAL APPLICATIONS

Industry, Renewable energy, Railway engineering, Energy, automation and building technology
