🧰 Features & Applications
-
Conditioned & calibrated output directly interfaceable to analog input modules without further signal conditioning. Output is average sensing but RMS‑calibrated. Burden impedance must be ≥ 1 MΩ to maintain ±0.5% accuracy.
-
Fully isolated and reverse‑polarity protected, making it safe for industrial control, energy monitoring, motor operation tracking, or OEM instrumentation.
-
Self‑powered—no external power required.
