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
The APR 50 B10 is a None current transducer from LEM.
Typical applications include 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 and Switching Power Supplies and Electronic Ballasts: True rms sensing is the most accurate way to measure power supply or ballast input power.
Key characteristics from the official datasheet: linearity error ±0.5 %; operating temperature −20 … +60 °C.
