Applications
VFD Controlled Loads:
VFD output indicates how the motor and attached load are operating
SCR Controlled Loads:
Accurate 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.
