Beskrivelse
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.
Key Features
- Input unit capable of DCV and ACV high voltage input
- Isolated 2 channel input
- Maximum rated voltage to ground: 1000 V AC or DC (CAT III), 600 V AC or DC (CAT IV)
- Directly input up to 1000 V DC or 700 V AC
- High-speed sampling of up to 1MS/s
Direct, high-voltage input without differential probes
The U8974 is ideal for measuring the primary and secondary sides of UPS power supplies and commercial power supply transformers. It can measure high-voltage power lines, including 380 V and 480 V circuits found in many countries. With high-speed sampling at up to 1 MS/s and 16-bit resolution, it can also be used in load rejection testing and switch testing.
Analyze correlations between phenomena, including voltage levels before and after generator disconnection, RPM fluctuation rates, governor servo operating status, and voltage governor switching timing.
