Remarks

•I

S is positive when IP flows in the direction of the arrow.

•Temperature of the primary conductor should not exceed

90°C.

•Dynamic performances (di/dt and response time) are best

with a single bar completely filling the primary hole.

•In order to achieve the best magnetic coupling, the primary

windings have to be wound over the top edge of the device.

•This is a standard model. For different versions (supply

voltages, turns ratios, unidirectional measurements...),

please contact us.
