The new Micro~flex ACP 1003_3 is a 3 Phase AC current
clamp utilising the Rogowski principle. It can be used to
measure currents up to 1000 Amps from very low
frequencies to 10kHz. The flexible and lightweight
measuring head allows quick and easy installation in hard to
reach areas and with large conductors.
