CSN Series CSNS300 Closed loop current sensors DESCRIPTION This new series of closed loop current sensor offers a flexible The sensors are closed loop devices and based on the solution to measuring currents up to ± 600 A. The sensors are principle of Hall effect and null balance method. The output small and have a large primary through hole to accept either a from the current sensor is the balancing current that is the cable or a variety of different busbar sizes. The sensors can perfect image of the primary current reduced by the number be mounted vertically or horizontally and come with of secondary turns at any time. The current can be expressed connection options of integral Molex type connector or a flying as a voltage by passing it through a load resistor. lead.
