AC/DC Hall sensor Current clamp

The current clamp meter enables the measurement of direct and alternating current.
It is therefore suitable for measuring battery storage systems and DC links.

Electrical properties
Measuring ranges	60 / 600 A DC 40 / 400 A AC (600 A AC_peak)
Output voltage	10 / 1 mV/A
Frequency range	DC up to 20 kHz

Phase error	< 2°

Measures
Inner diameter	32 mm
Connection	1.5 m signal cables with 2 x 4 mm banana plugs
Temperature range (operation)	0° C to +50° C

Cable connection set for current clamps

The free cable connection set must be used to connect other current clamps.

Switchable mini current clamp 20/200 A

The clamp is especially suitable for measurements on secondary transformers in MV or HV networks.
It offers very high accuracy and a small angular error.

20 A Measuring range
power range:	20 A AC RMS
Measuring range:	100 mA to 20 A RMS
Output voltage:	10 mV / A
Frequency range:	40 Hz to 5 kHz
Working voltage:	600 V AC / DC

Accuracy:

Accuracy	1.5% of M	1% v. M	0.5% of M
Angular error	0,5°	0,5°	0,5°

200 A Measuring range
This measuring range must be communicated to the network analyzer. The box is preset for the 20A measuring range of the mini current clamps. All values that deviate from this ratio must be corrected with the transformer factor in the measuring device. For the 200 A measuring range, the factor x10 must be set in the network analyzer.
power range:	200 A AC RMS
Measuring range:	5 A to 200 A RMS
Output voltage:	1 mV / A
