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

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
Frequency range::	40 Hz bis 5 kHz
Operating voltage:	600 V AC /  DC

Accuracy:
Current 50 Hz	100 mA - 10 A	>10 A - 20 A	>20 A
Accuracy	1,5% v. M	1% v. M	0,5% v. M
Angle error	0,5°	0,5°	0,5°

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
Operating voltage:	600 V AC / DC

Accuracy:
Current 50 Hz	>10 A - 40 A	>40 A - 100 A	>100 A - 200 A
Accuracy	<2 % v. M	<1,5 % v. M	<1 % v. M
Angle error	<2°	<1,5°	<1°
