Hioki U8974 - High Voltage Unit

U8974 High Voltage Unit for MR8847A
Directly input up to 1000 V DC or 700 V AC
For use with Hioki Memory Hicorder series
High-speed sampling up to 1MS/s

The Hioki U8974 input module features direct high –voltage input of up to 1000 V DC and 700 V AC without using a differential probe. This is ideal for primary and secondary measurements of UPS power supplies and commercial power supply transformers, for recording the primary and secondary waveforms of inverters, and for measuring high-voltage power supply lines, such as 380 V and 480 V systems used in many countries.
