VFD Controlled Loads:
VFD and SCR waveforms current
SCR Controlled Loads:
Switching Power Supplies and
Panel mounting
High isolation between primary and
VFD output indicates how the motor
and attached load are operating.
Acurate measurement of phase
angle fired or burst fired (time
proportioned)
SCRs. Current measurement gives
faster response than temperature
measurement.
True RMS sensing is the most
accurate way to measure power
supply or ballast input power.
