Description

Introduce

D-K3NT 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 currents.

Applications

Variable speed drives

Static converters for DC motor drives

Battery supplied applications

Uninterruptible Power Supplies (UPS)

Electrochemical

Directions for use

1.When the current will be measured goes through a Sensor, the voltage will be measured at the output end.(Note: The false wiring may result in the damage of the Sensor)

2. The output amplitude of the Sensor can be adjusted according to users’ requirements.

3. Custom design in the different rated input current and the output voltage are Sensor.
