PF330A Digital Power Meter
High precision, full function, three channels
Typical application scenarios
PF330A is a multifunction, wide band, 3 channel high accuracy digital power meter. It can measure DC, AC frequency range 0.5Hz-100kHz measurement.Besides, it can measure minimum 0.25μA current,It covers functions including harmonic analysis, integration, scaling, averaging, data/reviewing and communication, etc. Equipped with special software, quickly set measurement parameters, can display, store, call measurement data, can display voltage, current waveform and harmonic spectrum. Suitable for scientific research universities, testing and calibration, enterprise research and development, quality inspection and other high-demand occasions.
Main characteristics
1. Large current/voltage function
PF330A-H can realize 1500v/50A to directly measure the test occasions with large voltage and large current; it also has the current external input range of 2.5 mv ~ 10 v, making the test more convenient.
2. Integration measuring automatic range function
Integration is to accumulate the active power (W) or current (A) according to the time, to obtain the energy consumption (Wh) or power consumption (Ah), can obtain the power consumption of each operating state of household appliances. PF330A Not only can measure the positive and negative watt time, but also can measure the pere hour and DC current, can be used for battery charge and discharge energy, elevator lifting power consumption and storage measurement.
In integral mode, a fixed measurement range is required, and once the input voltage or current exceeds the maximum value of the selected range, the measurement will go wrong and the range needs to be increased. PF330A The range can be automatically and quickly switched in the integral mode, ensuring the accuracy and continuity of the measurement position.
3. Wide frequency measurement range
PF330A It has a frequency measurement range of DC, from 0.5 to 100 kHz. Measure the distortion waveform such as square wave, pulse wave or special waveform with DC components. Through the average active power measurement function, the distortion waveform can be accurately measured without any special mode setting, providing accurate power consumption data for the fluctuating power parts such as pulse wave, such as electric welding machine, HID power supply, etc.;
In the measurement of sine wave, such as testing the input waveform containing rich high frequency harmonic components, the measurement frequency range and bandwidth of the power meter is not enough, can not test the high frequency harmonic component, PF330A can ensure that the accurate measurement of power and power factors when testing such products.
4. Efficiency testing
PF330A With three measurement channels, a single instrument can measure the efficiency. Two channels use the "two-meter method" to measure the three-phase output signal of the inverter, and the other channel to measure the DC input of the inverter.
