Clarke-Hess 610 and 650 current shunts

The Clarke-Hess 610 and 650 current shunts are specifically designed to work with the Clarke-Hess 6000A Precision Phase Meter and Power analysers. These current shunts are frequency-optimised and offer a negligible phase shift of less than ±5 mº at 50/60 Hz. Thanks to their wide frequency range and high accuracy, the 610 and 650 shunts are suitable for power tests, phase angle measurements and calibration of power meters and analysers.

High accuracy and minimal phase shift

The Clarke-Hess 610 and 650 shunts are frequency-tuned, providing exceptionally stable performance:

• > Model 610: Current range 1A – 10A, frequency range 5 Hz – 100 kHz
  • * <5 mº phase shift up to 1 kHz
  • * 5mº + 50mº (f-1) above 1 kHz
• > Model 650: Current range 10A – 50A, frequency range 5 Hz – 1 kHz
  • * <5 mº phase shift up to 100 Hz
  • * <10 mº phase shift up to 500 Hz
  • * 50 mº phase shift above 500 Hz

Optimised for laboratory and industrial applications

The 610 and 650 models provide high-precision current measurement without significant phase errors, which is crucial for:

> Power measurements in power frequency and high frequency applications
> Calibration of current transformers and precision ammeters
> Research and development in power electronics and power quality testing
> Compatibility with the Clarke-Hess 6000A for accurate phase angle measurements
