Description
Description
Introduce

B201 series 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.

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
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.
