APR-B10_1 Datasheet, PDF (1/2 Pages) LEM – AC Current transducer
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.

LEM Components
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.
