Video review of ITECH IT9121 reference electrical power and energy meter

Watch this short video presentation of the electrical power and energy reference meter ITECH IT9121. It shows the functional and design features of this device and briefly lists its main advantages and strengths.

DETAILED DESCRIPTION

Electrical power meter ITECH IT9121 can carry out measurements in the range up to 600 V (RMS) for voltage and up to 20 A (RMS) for current, while the frequency band is up to 100 kHz. This device can measure: voltage, current, electric power, active energy, frequency, harmonics and other parameters. For visual observation of distortions of input signals, operation is provided in the oscilloscope mode along the voltage and current channel. In the standard configuration, the device contains all the necessary interfaces for integrating it into automated systems: USB, Ethernet, IEEE-488.2 (GPIB), RS-232. It also supports the connection of USB flash drives, on which you can save the measurement results. The basic accuracy for voltage and current is 0.1%, and for power 0.2%. In addition, the IT9121 electrical power meter contains many other useful features and functions,

The ITECH IT9121 meter measures all the main parameters of a single-phase network

To the main screen of the electrical power meter ITECH IT9121 you can display all the main parameters that characterize a single-phase AC network. In addition, the list of displayed parameters can be configured in any combination, at the request of the user. For example, you can display active power, RMS voltage and current on the screen, or you can add to them the mains frequency, peak voltage and current values, and any other parameters from the list of possible ones.

ITECH IT9121 meter measures up to 50 voltage and current harmonics

Distortions (deviations from the sinusoidal form) of the voltage and current of a single-phase network are an important component of assessing the quality of such a network. To provide the user with comprehensive information about the distortion of the measured signals, the ITECH IT9121 device provides a measuring band in the voltage and current channels equal to 100 kHz. Such a wide bandwidth allows accurate measurement of up to 50 harmonics of the fundamental frequency of the network. The device screen displays a graphical representation of the level of each harmonic and numerical results: the level of each harmonic in Volts or Amps, frequencies, harmonic distortion, etc.

ITECH IT9121 electrical power and energy meter oscilloscope mode

Power meter ITECH IT9121 can work in the oscilloscope mode, showing the results of digitization of input voltage and current signals. The voltage waveform can be displayed on the instrument screen simultaneously with the current waveform. This mode of operation greatly simplifies and reduces the cost of measurements and the search for the causes of distortions of a single-phase network, as it allows you to do without the use of a separate oscilloscope with galvanically isolated inputs. There is also no need for separate high-voltage voltage dividers and current transformers.

The design of the reference meter ITECH IT9121

Meter ITECH IT9121 made in a compact laboratory case, equipped with a 10.9 cm color screen (with a resolution of 480 x 272). The device comes standard with interfaces: USB, Ethernet, IEEE-488.2 (GPIB), RS-232. The mass of the device is 2.6 kg, overall dimensions: 255 x 108 x 388 mm. Working temperature: from +5°С to +40°С. Warm-up time: 30 minutes. The photo below shows a view of the rear panel of the ITECH IT9121. Powerful current signal connection terminals are located at the bottom left.

IT-E185 - device for connecting the measurement object to the ITECH IT9121 meter

If it is necessary to measure the consumption or generation parameters of a particular device, such as an uninterruptible power supply, then it is more convenient to connect it to the ITECH IT9121 meter through a special device: ITECH IT-E185. The ITECH IT-E185 device is connected "into the gap" between a single-phase network and the IT9121 reference meter. Using the IT-E185 greatly simplifies and makes the connection safe, since all the necessary patch wires are hidden inside its case.
