AcuAMP ACTH Series AC Current Transducer Manual

This document details the AcuAMP ACTH Series AC current transducers, which are 1-phase, split-core devices designed for monitoring current from zero-crossing burst-fired SCR controllers, particularly for electrical heaters. They feature an innovative time integration adaptive True RMS measurement method, a 4–20 mA output, and selectable sensing ranges (0–2/0–5 A or 0–10/0–20/0–50 A), with specifications including a 24 VAC/DC power supply, 400 ms response time, and cULus/CE certifications.
