Current Transducer
Closed loop current sensor based on the principle of Hall-effect. It can be used formeasuring AC,DC,pulsed and mixed.
For the electronic measurement of currents : DC, AC, pulsed... with a galvanic isolation between the primary circuit ( high power ) and the secondary circuit ( electronic circuit ) .
Applications
* AC variable speed drives and servo motor drives
* Static converters for DC motor drives
* Battery supplied applications
* Uninterruptible power supplies (UPS)
* Switched mode power supplies ( SMPS )
* Power supplies for welding applications
