Typical Application Scenarios

The PF310A series is a high-precision multifunctional digital power meter with wide frequency range. It supports DC and 0.5Hz-100kHz wide-band testing, with a minimum measurable current of 25μA, making it ideal for standby power measurement. It also features multiple functions including harmonic analysis, ratio setting, averaging, data storage/recall, and electrical energy integration. Equipped with dedicated software, it enables quick configuration of measurement parameters, can display, store and recall measurement data, and display voltage and current waveforms as well as harmonic spectrum. The PF310A digital power meter meets the application requirements of AC/DC, variable frequency and standby power testing in production, testing, evaluation, scientific research and other fields, and is suitable for high-requirement scenarios such as universities & research institutions, testing & calibration, enterprise R&D, and quality inspection.

Main Features

1. Minimum measurement current of 25μA

With a minimum measurement current as low as 25μA and maximum power measurement resolution of 1µW, it is very suitable for standby power testing and complies with international standards (IEC62301, Energy Star, SPEC power).

2. Maximum test voltage 1500V, direct measurement current 50A

The PF310A-H supports 1500V/50A direct measurement, which meets the testing requirements of high-voltage and high-current scenarios; it also supports external current input range of 2.5mV~10V, making testing more convenient.

3. Automatic ranging for integration measurement

Integration accumulates active power (W) or current (A) over time to obtain energy consumption (Wh) or electricity consumption (Ah), which can get the power consumption of household appliances under various operating conditions. The PF310A series digital power meter can not only measure positive and negative watt-hours, but also ampere-hours and DC current, which can be used for measurement of battery charge and discharge energy, elevator lifting energy consumption and storage, etc. Usually, the measurement range needs to be fixed in integration mode. Once the input voltage or current exceeds the maximum value of the selected range, the measurement will fail, and the range needs to be increased for re-testing. The PF310A series digital power meter can automatically and quickly switch ranges in integration mode, ensuring the accuracy and continuity of measurement.

4. Wide frequency measurement range

The PF310A series supports DC and 0.5~100kHz frequency measurement range, and can measure the RMS value of distorted waveforms such as square waves, pulse waves or special waveforms with DC components. Through the average active power measurement function, it can accurately measure distorted waveforms without any special mode settings, providing accurate power consumption data for fluctuating power devices such as welding machines, HID power supplies and other pulse-type power equipment; When measuring sine waves, for example, when testing products with rich high-frequency harmonic components in input waveforms such as switching power supplies and variable frequency home appliances, if the measurement frequency range and bandwidth of the power meter are insufficient, the high-frequency harmonic components cannot be tested correctly. The PF310A series digital power meter can ensure accurate measurement of power and power factor when testing such products.
