· VFD Controlled Loads:

VFD output indicates how the motor

and attached load are operating.

· Switching Power Supplies and

Electronic Ballasts:

Note: ¹⁾For 4-20mA output model, no saturation output up to 23 mA.

True RMS sensing is the most

accurate way to measure power

supply or ballast input power.

Selecting the transducer

VFD (Variable Frequency Drive) and SCR (Semi Conductor Rectifier) output

waveforms are rough approximations of a sine wave. There are numerous spikes

and dips in each cycle. AKR transducers use a mathematical algorithm called

“True RMS,” which integrates the actual waveform over time. True RMS is the only

way to accurately measure distorted AC waveforms. Select AKR transducers for

nonlinear loads or in “noisy” power environments.
