Catalog excerpts

RTC50HR33 series multi-range current sensor is a closed loop device 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. 1.When the current will be measured goes through a sensor ,the voltage will be measured at the output end. 2.(Note: The false wiring may result in the damage of the sensor). 3. Custom design in the different rated input current and the output voltage available.
