B203 Type Current Sensor

Introduce:

B203 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.

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.
