Description
Description
Introduce

K3 series hall effect current sensor is an open loop device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, AC or pulsed currents.

Applications
Variable speed drives
Welding machine
Battery supplied applications
Uninterruptible Power Supplies (UPS)
Electrochemical
Directions for use
When the current will be measured goes through a sensor, the current will be measured at the output end. (Note: The false wiring may result in the damage of the sensor)
Custom design in the different rated input current and the output current are available.
