AN87500(F) multi-channel power analyzer is specially designed for multi-channel AC/DC power measurement, suitable for power measurement of most electrical appliances, power supplies, motors, inverters and other products. The product takes the high-speed DSP processor as the core, adopts 16-bit high-speed high-performance AD direct sampling method for data acquisition, and can realize multi-channel simultaneous measurement, covering: voltage, current, power, peak voltage, peak current, power factor, crest factor, frequency, electric energy, current integral, efficiency, harmonic content and 3-phase electrical parameters, with serial communication (RS232/RS485, GPIB), remote control, alarm parameter preset and so on, supporting 1P2W/1P3W/3P3W/3V3A/3P4W and other wiring methods, meeting testing requirements of various power supply.
Features:
Multi-channel: 1~6 channels, flexible configuration of 1~6 single-phase, three-phase three-wire Ã?? 2, three-phase four-wire Ã?? 2, four-phase (DC+ three-phase three-wire) and other modes, satisfy test requirements of varies load (air conditioner, converter, inverter, motor);
High accuracy: high-speed DSP processor, 16-bit high-speed high-accuracy AD converter, accuracy up to 0.1%, 100ms display cycle;
Wide power range: current up to 50A for a single channel (optional 20A, 10A, 5A, 2A, 1A etc. or combination), minimum 0.lmW power resolution, satisfy test requirements of standby power consumption and rated power;
Broadband: AC/DC signals, power measurement bandwidth: DC, 0.5Hz~100kHz, satisfy power test requirements of varies standard and non-standard sine wave load;
Multi harmonic analysis: simultaneous 6-channel harmonic analysis, maximum 50th harmonic measurement, distortion analysis, visual display of total harmonic contents and total contents;
Multi frequency measurement: simultaneous 6-channel frequency measurement;
Line filtering: 500Hz/5.5kHz low-pass filter to measure the fundamental PWM waveform, filter out the high-frequency interference of the switching power supply current;
Sensor: variable ratio, common I-I/V-V voltage/current transformers; I-V type current sensor with BNC interface, maximum input voltage 10V, optional high current sensor;
Efficiency calculation: measure the input/output energy consumption of the equipment at the same time, and calculate its efficiency;
Accumulation of electric energy: positive electric energy, reverse electric energy and integrated electric energy can be separately accumulated to measure the trading electric energy;
Threshold alarm: independent 10 groups of voltage, current, power, power factor and other thresholds and measurement threshold for each channel, automatic upper/lower limit judgment and alarm;
Chinese/English interface: Chinese or English operation and time/date display.
