GMW Hall-effect current sensor CPC-2000-27-BP2 clamp-on AC/DC probe 27 mm aperture 0-2000A

PROBEMART offers the GMW CPCO/CPC clamp-on (split-core) Hall-effect current sensor, which can measure AC/DC current from DC to 50 kHz and 0–16000 A with an overall measurement accuracy of 1%; it is mainly used for current testing of electric vehicles, motors, PV inverters, variable-frequency drives, battery charging/discharging, electromagnetic actuators, etc.It can usually be used with various power analyzers, recorders, data acquisition units, and oscilloscopes for testing.

The Hall-effect current transformer measures the DC component based on the magnetic-balance Hall effect principle and the AC component based on the magnetic induction principle: when a current C is passed through the control-current terminals of the Hall element and a magnetic field with magnetic flux density B is applied along the normal to the plane of the Hall element, a potential VH is generated in the direction perpendicular to both the current and the magnetic field (i.e., between the Hall output terminals); this is called the Hall potential, and its magnitude is proportional to the control current. Hall-effect current probes are particularly suitable for high-precision AC+DC measurement scenarios.
