General

Introduce:

B1 series multi-range current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, AC or pulsed currents.

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.

Applications:

AC 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.
