Applications
* VFD Controlled Loads: VFD output indicates how the motor and attached load are operating. * SCR Controlled Loads: Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement. * Switching Power Supplies and
