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.

I

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.

Application domain

• Energy and Automation
