AC Current transducer APR-B420L
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 4-20mA current output.

Features
VFD and SCR waveforms current
measurement
True RMS output
Split core type
Loop powered 4-20mA current output
DIN mounting & Panel mounting
Eliminates insertion loss
Switch selectable ranges
Advantages
Large aperture for cable up to 18mm
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.
