D7 Type Current Sensor

Introduce:

The D7 Series current sensor is a closed loop device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit, the size of primary doesn’t affect test precision, no matter the location of primary in the hole of current sensor. It can really measure resolution 1000:1, it uses for precision measurement of DC, AC and pulse current.

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:

  • Variable speed drives
  • Welding machine
  • Battery supplied applications
  • Uninterruptible Power Supplies (UPS).
  • Electrochemical
