Instructions of use
1
When the test current passes through the sensor, you can get the size of the output current. (Warning: wrong
connection may lead to sensors damage.)
2
I
s
is positive when I
p
flows in the direction of the arrow.
3
In order to achieve the best magnetic coupling, the primary windings have to be wound over the top edge of the
device.
4
According to user needs, different rated input currents and output currents of the sensors can be customized.
