ITECH IT9121 AC/DC Power Meter 600 Vrms/20Arms

Manufacturer: ITECH Electronic Co
Product Number: IT9121

Product Description

The IT9121 power meter can have maximum input of 600Vrms and 20Arms with measurement bandwidth of 100KHZ, and can be easily used for measuring the voltage, current, power, frequency, harmonics and other parameters. The standard configuration includes USB, GPIB, RS232 and LAN communication interfaces and also interfaces for USB-based peripheral devices. The user can save the measured parameters into the external storage medium. The basic voltage and current accuracy is 0.1%. Moreover, the power meter has rich integrating functions, such as the active power. It is widely applied in test of motors, household appliances, UPS, etc.
