Overview

The IsoCap I-ST-1c is a sensor designed for high-quality isolated current measurements up to 100 Amperes. The IsoCap I-ST-1c module provides 1500VAC primary-to-secondary sustained isolation, which allows users to monitor a miscellaneous of currents at different potentials. IsoCap I-ST-1c uses shunt methodology to measure the current flowing through the input conductor. In essence, this technique works by placing a high performance low impedance resistor along the current path (primary), while a galvanic isolation separates primary and secondary sides.
The compact form factor of the IsoCap I-ST-1c module allows users to setup high channel density monitoring systems, making it ideal for deployed and portable systems.
