CDS4000 family Compact AMR current sensors with overcurrent detection

The CDS4000 current sensor family is designed for the electronic measurement of alternating and direct currents and also offers a safe isolation of the measurement signal and the evaluation circuit.

The sensors offer

  • A measurement range of up to 3 times the rated current
  • Galvanic isolation
  • Unipolar 5 V supply voltage 
  • Various variants for different measurement ranges

This product family has eight sensor variants for you to choose from.

  • CDS4006 for 6 A rated current
  • CDS4010 for 10 A rated current
  • CDS4015 for 15 A rated current
  • CDS4025 for 25 A rated current
  • CDS4050 for 50 A rated current
  • CDS4100 for 100 A rated current
  • CDS4125 for 125 A rated current
  • CDS4150 for 150 A rated current

Advantages:

  • High signal-to-noise ratio
  • Excellent accuracy
  • A low temperature drift
  • A low primary inductivity

The CDS400 in the THT housing and unipolar 5 V voltage supply is ideally suited for low-noise measurement tasks due to the particularly high output voltages, such as: 

  • Measurement technology
  • Solar/frequency inverters
  • Switching power supplies
  • Uninterruptible power supply

General information MagnetoResistive current sensors

The CDS4000 current sensor family was designed for highly dynamic, electronic measurement of alternating and direct currents and also offers a safe isolation of the measurement signal and the evaluation circuit. 

The MR technology enables an excellent dynamic response time and is not afflicted with a hysteresis, as is often the case in iron core-based current sensors. The CDS4000 current sensor family offers sensors for PCB mounting for a rated current range of 6 A to 150 A and are ideally suited for measurement tasks in the field of power electronics.

CDS4000 family

The sensors primarily differ in the different current ranges. There are two different sizes – a slightly more compact version for small current ranges of up to 50 A and a slightly larger housing for currents of over 50 A.

The current sensors are perfectly calibrated to the usage current range during production.
