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.

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.
