Applications

-AC Power Supplies or Motors

True RMS sensing - the most accurate way to monitor power supply or input power

-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 proportional) SCR's and switch mode rectifiers. Current measurement gives faster response than temperature measurement.

-Renewable Energy Installations or Backup Batteries

Continuous condition monitoring allowing automatic failure detection and prediction

-Application Domain
