AC Current transducer APR-B420L

I_PN= 10 .. 400 A

Split core transducer for the electronic measurement distorted AC

waveforms current, with galvanic isolation between the primary circuit

(power) and the secondary circuit (measurement). Switch selectable

ranges and True RMS 4-20mA current output.

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
