Current Sensors
Instructions of use
1) When the test current passes through the sensors you can get the size of the output
voltage.(Warning: wrong connection may lead to sensors damage)
2) Based on user needs, the sensors output range can be appropriately regulated.
3) According to user needs, different rated input currents and output voltages of the sensors can be
customized.
