Flexible alternative to the current shunt or transformers for the isolated measurement of a.c. or d.c. currents. Both types have plastic Bayblend KU1468 UL94-VO cases.,High current types have current sensors based on the hall effect and null balance method. The output is the balancing current which is a perfect image of the primary current reduced by the number of secondary turns at any time. It can be expressed as a voltage by passing it through a resistor.,Multi-range types are similar devices but with a wider measuring range. Up to 36A is possible using 5 primary turns and up to 43A using 7 primary turns.
