I
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.
