Description

Product information U8974 - High Voltage Unit

The U8974 High Voltage Unit is a 2-channel voltage measurement module for high-voltage signals for the memory recorders MR6000, MR6000-01, MR8848, MR8827, MR8740, MR8741 and MR8740T. It supports DC and RMS voltage measurement with selectable modes and enables direct input of high-voltage signals. The module provides measurement ranges from 200 mV/div to 50 V/div (DC) and 500 mV/div to 50 V/div (RMS) with a maximum input voltage of 1000 V DC and 700 V AC. Simultaneous sampling of both channels is performed at up to 1 MS/s with 16-bit A/D conversion. A frequency characteristic from DC to 100 kHz and integrated RMS measurement functions support analysis of voltage signals. 

Typical applications include measurement of high-voltage signals in power electronics, monitoring of power supply systems, and analysis of voltage waveforms in electrical systems.
