Description

Product information U8977 - 3ch Current Unit

The U8977 3ch Current Unit is a 3-channel current measurement module for the memory recorders MR6000, MR6000-01, MR8740T, MR8847A, and MR8848. It enables current measurement with optional Hioki current sensors. The module supports direct connection of compatible current sensors as well as connection via the optional CT9920 Conversion Cable. It also supports automatic recognition of directly connectable sensor models for automatic scaling setup and supplies sensor power directly from the current unit. Typical applications include 3-phase current measurement, inverter testing, and wideband current waveform acquisition in power electronics evaluation.
