Hioki VT1005 AC/DC High Voltage Divider

Overview

The Hioki VT1005 is an AC/DC high voltage divider that safely reduces voltages up to 5000V to levels compatible with power analyzers. With a 1000:1 divider ratio, it enables accurate measurement of high-voltage systems including inverters in rail and power applications. The device features excellent frequency flatness from DC to 4MHz, allowing precise measurement of both fundamental and switching frequency components.
