ATR' transducers from NK Technologies combine a current transformer and a True RMS signal conditioner into a single package. The ATR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs and on linear loads in "noisy" power environments. Available in a solid or split core case.

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 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.

Features
True RMS Output
 
Jumper Selectable Ranges
Reduces inventory.
Eliminates zero and span pots.
Isolation
Output is magnetically isolated from the input for safety.
Eliminates insertion loss (voltage drop).
UL, CUL and CE Approval
Accepted worldwide.
