Typical Application Scenarios
PF310A series is a multi-function digital power meter with wide frequency and high accuracy, which can realize DC and 0.5Hz-100kHz wide frequency test, and the minimum current can be measured 25μA, which is very suitable for standby power consumption measurement. At the same time with harmonic analysis function, ratio function, averaging function, data storage / transfer function, electric energy integration and other functions. Equipped with special software to quickly set measurement parameters, display, store and recall measurement data, and display voltage, current waveforms and harmonic spectra, the PF310A Digital Power Meter is suitable for AC/DC, inverter, and standby power consumption testing, as well as production, testing, evaluation, and scientific research and other areas of application needs. It is suitable for scientific research and universities, testing and calibration, enterprise research and development, quality inspection and other demanding occasions.
Main features
I. Minimum measurement current 25μA
Minimum measurement currents as low as 25µA and maximum power measurement resolution of 1µW are ideally suited for standby power testing in accordance with international standards (IEC62301, Energy Star, SPEC power).
Second, the highest test voltage 1500V, direct current 50A
PF310A-H can realize 1500v/50A direct measurement to meet the large voltage, large current test occasions; also has a current external input range of 2.5mv~10v, making the test more convenient.
III. Integral measurement auto range function
Integration is the accumulation of active power (W) or current (A) by time to obtain the energy consumption (Wh) or power consumption (Ah), which can be used to obtain the power consumption of household appliances in various operating states.PF310A series digital power meter can not only measure the positive and negative watt-hours, but also measure the ampere-hours and DC current, which can be used for battery charging and discharging, elevator lifting and power consumption and storage measurements, etc. Usually, it is necessary to fix the measurement range in the integration mode, once the input voltage or current exceeds the maximum selected range, the measurement will be wrong. The PF310A series of digital power meters can automatically and quickly switch between ranges in integral mode to ensure accuracy and continuity of the measurement.
Wide frequency measurement range
The PF310A series has a DC, 0.5 to 100kHz frequency measurement range. The PF310A series is capable of measuring the RMS value of distorted waveforms such as square waves, pulse waves, or special waveforms containing DC components. Through the average active power measurement function, it can accurately measure the distorted waveforms without any special mode settings, and provide accurate power consumption data for pulse wave and other fluctuating power components such as welding machines, HID power supplies, etc.; When measuring sine waves, such as testing switching power supplies, inverter appliances, etc., which contain rich high-frequency harmonics in the input waveforms, the power meter's frequency range and bandwidth are not sufficient to test the high-frequency harmonic components, PF series has a DC, 0.5~100kHz frequency measurement range. When measuring sinusoidal waveforms, such as switching power supplies and inverter appliances, where the input waveform is rich in high-frequency harmonics, the power meter's measurement frequency range and bandwidth are insufficient to test the high-frequency harmonic components.
