ISOBLOCK I-ST-1C (90A 10V)

Current Sensors Overview

The Verivolt ISOBLOCK I-ST-1C (90A 10V) is a high-performance current sensor designed for accurate measurement of currents up to 90 Amperes. It utilizes a shunt-based isolation method, providing 1500V continuous and 5000V peak isolation between primary and secondary circuits. The device features a bandwidth from DC to 100kHz and delivers an output signal of ±10V. Powered by a 9 to 28VDC supply, it offers a response time of 2.8µs with an accuracy of ±0.2%. The unit is housed in a DIN rail mountable enclosure with spring terminals.

Current Sensors Procurement Notes

Verify the specific model suffix against official Verivolt documentation to confirm input range and output scaling. Ensure the required supply voltage matches the 9-28VDC specification. Confirm that the 1500V working isolation rating meets safety requirements for the intended application environment before finalizing procurement.

Current Sensors Selection Notes

Select this component when precise measurement of high-amplitude AC or DC currents is required within a noisy electrical environment. The shunt-based technology ensures linearity, while the high isolation voltage protects downstream electronics. Consider the ±10V output compatibility with existing analog input modules and verify that the DIN rail form factor fits the available panel space.

Current Sensors Part Context

This sensor belongs to the IsoBlock I-ST series, which specializes in robust current isolation. Unlike Hall-effect sensors, this model uses a low-impedance shunt resistor to sense current, offering superior stability and bandwidth. It is part of Verivolt's portfolio aimed at simplifying integration into complex industrial monitoring systems through standardized mounting and signaling.
