VFD and SCR waveforms current

measurement

True RMS output

4-20 mA current output

Panel mounting

Eliminates insertion loss

Isolated plastic case recognized

according to UL94-V0

Large aperture for cable up to

Ø32mm

High isolation between primary

and secondary circuits

Easy installation

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.
