B9 Type Current Sensor

B9 Type Current Sensor

Description

Description

Introduce

B9 series current sensor is a closed loop device based on the 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.
