LEM APR200-B420L Ac current transducer apr-b420l Datasheet

AC Current transducer APR-B420L
IPN = 10 .. 400 A
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.

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

• Switching Power Supplies and
Electronic Ballasts:
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
Notes : Installation and maintenance should be done with power supply disconnected.
