Remarks

•I S is positive when I P flows in the direction of the arrow.•Temperature of the primary conductor should not exceed

100°C.

•Dynamic performances (di/dt and response time) are best with a single bar completely filling the primary hole.

•This is a standard model. For different versions (supply voltages, turns ratios, unidirectional measurements...),please contact us.
