AC/DC CURRENT CLAMP (switchable)

The current clamp makes it possible to measure direct and alternating current.
Therefore, it is suitable for measurements of battery charge and intermediate direct current circuits.

60 A measuring range

Measuring range: 200 mA to 60 A RMS
Output voltage: 10 mV / A
Frequency range: DC bis 10 kHz
Accuracy:
Current 0-65 Hz 0,5...40 A 40...60 A (only for DC)
Deviation <1,5 % + 5 mV <1,5 %
Current 45...65 Hz 10...20 A 20...40 A
Phase errors <3° <2,2°
600 A measuring range
Current range: 600 A AC/DC RMS
Measuring range: >0,5mA to 600 A RMS
Output voltage: 1mV / A
Frequency range: DC bis 10kHz

ADAPTER SET FOR EXTERNAL CURRENT CLAMPS

The free adapter set can be used to connect any other current clamps.


SWITCHABLE MINI CURRENT CLAMP 20/200A

The current clamp is particularly suitable for measurement at secondary converters in medium voltage or high voltage networks.
It offers high accuracy as well as small angle error.

 

20 A measuring range

Current range: 20 A AC RMS
Measuring range: 100 mA to 20 A RMS
Output voltage: 10 mV / A

200 A measuring range

This measuring range has to be forwarded to the network analyzer. The box is preset for the 20A measuring range of the mini current clamps. All values deviating from this ratio have to be corrected with the conversion factor of the measuring device. For the 200 A measuring range, adjust the factor x10 in the network analyzer.

Current range: 200 A AC RMS
Measuring range: 5 A to 200 A RMS
Output voltage: 1 mV / A
Frequency range: 40 Hz to 10 kHz
