Sensors and limit switches

The CurrentWatch EACR Series current sensor family combines a current sensor and a “true rms” signal into a single package.

The EACR Series provides true rms output on distorted waveforms found on variable frequency drives or silicon-controlled rectifier outputs, and on linear loads in “noisy” power environments.

Available in solid- or split-core housings.

Overview Configure Resources Support

EACR series CurrentWatch RMS current sensors core features

True rms output—true rms technology is accurate on distorted waveforms like VFD or SCR outputs
Jumper-selectable ranges—reduces inventory and eliminates zero and span

Isolation—output is magnetically isolated from the input for safety and elimination of insertion loss (voltage drop)

Application in which the EACR series current sensors excel

VFD controlled loads—monitoring Vdc 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, with faster current measurement than temperature sensors
Switching power supplies and electronic ballasts—true rms sensing is the most accurate way to measure power supply or ballast input power
