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 proportional) SCR's. Current measurement gives faster response than temperature measurement

-Application Domain

Energy and Automation
