2 AT Series True MS AC Current Transducers VFD Controlled oads VFD output indicates how the motor and attached load are operating. SC Controlled oads Accurate measurement of phase angle fired or burst fired (time proportioned) SCs. Current measurement gives faster response than temperature measurement. Switching Power Supplies and lectronic Ballasts True MS sensing is the most accurate way to measure power supply or ballast input power A 54.7Hz VFD Two Wire nstallation is Fast and asy True MS even on VFDs or SCs True MS AC Current Transducers AT Series PAG 2 AT transducers from K Technologies combine a current transformer and a True MS signal conditioner into a single package. The AT Series provides True MS output on distorted waveforms found on VFD or SC outputs and on linear loads in noisy power environments. Available in a solid or split core case. Field Selectable anges M Selecting the right transducer: VFD and SC output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. AT transducers use a mathematical algorithm called True MS, which integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True MS is the only way to accurately measure distorted AC waveforms. Select AT transducers for nonlinear loads or in noisy power environments. The current waveform of a typical linear load is a pure sine wave. AT transducers measure the peaks of these sine waves, then calculate the average amperage. This works well on constant speed linear loads in a clean power environment. Select AT transducers for strictly linear loads on clean power. True MS True MS technology is accurate on distorted waveforms like VFD or SC outputs.

OAD AG Series sensors from K Technologies protect people, products and processes from ground faults by monitoring all current-carrying wires in grounded single or 3- phase systems. Operating Principal: Under normal conditions, the current in the hot leg of a two-wire load is equal in strength but opposite in sign to the current in the neutral leg. These two currents create magnetic fields that are also equal but opposite. When the wires are next to each other, the fields cancel, producing a Zero Sum Current. f any current leaks to ground from one wire (Ground Fault), the two currents become imbalanced and the result is a net magnetic flux or field. AG Series ground fault sensors monitor this field and alarm when leakage rises above setpoint. This concept applies to grounded 3-phase delta and wye systems.
