* It is based on the measuring principle of the hall effect and null balance method, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, AC or pulsed currents.             


Advantages
* High accuracy
* Very good linearity
* Low temperature drift
* Low power consumption
* Can be customized
* Optimized response time, no insertion losses
* High immunity to external interference

Applications

* AC variable speed drives
* Static converters for DC motor drives
* Battery supplied applications
* Switched Mode Power Supplies (SMPS)
* Power supplies for welding applications
