AC Current transducer APR-B10

Split-core transducer for the electronic measurement AC currents (all waveforms), with galvanic isolation between the primary circuit (high power) and the secondary circuit (electronics). Switch selectable measuring ranges and true RMS 0-5V and 0-10V switch selectable voltage output.

特性 Features

• VFD and SCR waveforms current measurement

• True RMS output (average)

• Split-core type

• 0-5VDC & 0-10VDC switch selectable voltage output

• DIN rail or Panel mounting

• Switch selectable measuring ranges

• Isolated plastic case recognized according to UL94-V0.

Advantages

• Large aperture for cable up to Ø18mm

• High isolation between primary and secondary circuits

• Eliminates insertion loss

• Easy installation

Applications

• VFD Controlled Loads:

VFD output indicates how the motor and attached load are operating.

• SCR Controlled Loads:

Acurate measurement of phase angle fired or burst fired (time proportioned)

SCRs. Current measurement gives faster response than temperature measurement.

• Switching Power Supplies and Electronic Ballasts:

True RMS sensing is the most accurate way to measure power supply or ballast input power.
