Type 20 A | 200 A | 500 A | 1.000 A
The CSM Current Clamp is a ready-to-connect solution for current measurements up to ±1,000 A. With the integrated supply module, the current clamp can be installed quickly and easily.
The CSM Current Clamps are suitable for high-precision measurements of currents up to ±1,000 A with signal frequencies up to 1 MHz.
The current clamp can be quickly and easily attached to the power cables to be measured. The integrated supply module contains the cables for the necessary supply voltage. This allows the CSM Current Clamp to be used quickly and flexibly.
Up to four CSM Current Clamps are connected to one measurement module of the CSM AD4 ECAT MiniModule series.
The current clamp ensures galvanic isolation between test setup and measurement technology. This makes the CSM Current Clamps also suitable for applications in 48 V electrical systems and HV environments.

The CSM Current Clamp is suitable for fast and uncomplicated current measurements, both in 12 V / 48 V vehicle electrical systems and in HV environments.
If the voltage is additionally measured with measurement modules of the CSM AD4 ECAT MiniModule series, power calculations can also be performed with the Vector CSM E-Mobility Measurement System.
