The IT9100 power meter offers a maximum input of 1000 Vrms and 50 Arms with a measurement bandwidth of 100 KHz. It easily measures voltage, current, power, frequency, harmonics, and more. Standard interfaces include USB, RS232, and LAN, along with USB for peripheral devices. Users can save measured parameters to external storage. The meter has a basic voltage and current accuracy of 0.1% and includes functions like active power measurement. It is widely used for testing motors, household appliances, UPS, and other devices.
Features
- 4.3-inch color LCD (TFT)
- Input range: 1000 Vrms / 50 Arms
- Harmonic Detection (Optional function for IT9121E)
- The accuracy of voltage and current measurement is up to 0.1%
- The voltage, current, power, harmonics, and other parameters can be measured at the same time
- The power meter has a harmonic measurement function and can measure up to the 50th harmonics
- The power meter has rich and powerful integrating functions, and can measure electric energy which is bought or sold
- Interfaces for USB-based peripheral devices are provided, and the user can save data to external storage
- Standard built-in USB, RS232, and Ethernet communication interfaces (For any GPIB interface option request , check with Welectron for availability.)
