DC-CT® Industrial Smart Series with Wide Opening¶
Preliminary Product, available in 2026Q4 - 2027Q1
This series is an industrial, galvanically isolated, precision, closed-loop Smart current transducer based on ISOTEL’s DC-CT® proprietary technology and the patented Platiše Flux Sensor. It integrates IEEE 1451.4 TEDS for plug-and-play self-identification and self-description, ISOTEL I-Wire diagnostic interface, and a fail-safe range/fault signal bringing smart sensor capability to industrial current measurement.
Key features
Platiše Flux Sensor Closed-Loop Transducer
10x Performance Compared to Competing Products
Excellent temperature stability
Standard industrial connection (3 or 4 wire, bipolar supply)
ISOTEL I-Wire for Identification, Description, Diagnostic and Fast Primary Tracking Fault
