Current Measurement up to 100A
The IsoBlock I-ST is a sensor designed for high-quality isolated current measurements up to 100 Amperes. The IsoBlock I-ST module provides 1500V primary-to-secondary sustained isolation, which allows users to monitor a miscellaneous of currents at different potentials. The IsoBlock I-ST uses an anti-aliasing filter and a conditioning stage to output a ±10V signal.
Shunt Methodology
The IsoBlock I-ST 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 input current is then obtained by amplifying the voltage induced across the shunt resistor.
Compact Form Factor
The compact form factor of the IsoBlock I-ST module allows users to setup high channel density monitoring systems, making it ideal for deployed and portable systems.
FAQ
The IsoBlock I-ST-1c is an isolated shunt that measures AC or DC, it will scale down or up the input signal according to the input/output ratio, outputting an instantaneous measurement in volts, which is ideal for most off-the-shelf data acquisition devices.
No, the IsoBlock I-ST-1c outputs and instantaneous measurement, when connected to an AC signal , the output signal will mirror the input with the same characteristics scaling it down or up depending on the Input/Output ratio.
In the event of an overcurrent at the input, the module will saturate the reading at the maximum output value. The IsoBlock I-ST-1c can withstand some level of overcurrent without being damaged or being degraded, if you believe this feature is of importance please get in touch with our technical sales team at sales@verivolt.com.
While the off-the-shelf sensor offered does not have an overcurrent protection feature, Verivolt does provide customized units prepared for specific needs, if you believe you would benefit from overcurrent protection, please get in touch with our technical sales team for a discussion at sales@verivolt.com
For the IsoBlock I-ST modules, the scaling ratio is fixed, which means that it can't be manually modified by the customer. The scaling ratio is defined during the assembly and calibration of the module.
