K3NT Type Current Sensor

K3NT Type Current Sensor

Description

Description

Introduce

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, AC or pulsed currents.

Applications

Variable speed drives

Static converters for DC motor drives

Battery supplied applications

Uninterruptible Power Supplies (UPS)

Switched Mode Power Supplies (SMPS)

Power supplies for welding applications

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.
