APR-B10_08 Datasheet, PDF (1/4 Pages) LEM – AC Current transducer
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.

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.
