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
