AC Current transducer APR-B10

Split core transducer for the electronic measurement distorted AC

waveforms current, with galvanic isolation between the primary (High

power) and the secondary circuits (Electronic circuit). Switch selectable

ranges and True RMS 0-5V and 0-10V switch selectable voltage output.

I

030708/0

Features

• VFD and SCR waveforms current

measurement

• True RMS output

• Split core type

• 5V & 10V switch selectable voltage

output.

• DIN mounting & Panel mounting

• Eliminates insertion loss

• Switch selectable ranges

Advantages

• Large aperture for cable up to Ø18mm

• High isolation between primary and

secondary circuits

• Easy to mount

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.
