The BK Precision 5335C Single-Phase AC/DC Power Meter is for measuring and analyzing power consumption and power quality parameters quickly and accurately. It supports power measurements up to 600 Vrms and 20 Arms, with a bandwidth up to of 100 kHz. The 5335C measures all AC and DC parameters, including power, current, voltage, power factor, frequency, and phase. Additionally, this meter features a powerful integration function, the ability to perform harmonic measurements to the 50th order, and an oscilloscope mode. The front panel features an intuitive user interface with a large 4.3 inch color LCD screen capable of displaying measurement results in numeric or graphical format, dedicated function keys for 4 main measurement modes, and a USB host port. The meter measures all AC and DC parameters including power, current, voltage, power factor, frequency, and phase difference. Additionally, the 5335C features a powerful integration function which is useful for analyzing energy produced and consumed. It can also be used to evaluate total harmonic distortion (THD) to the 50th order and it can display voltage and current readings in the time domain with the oscilloscope function. The meter is optimized for pre-compliance testing according to international standards such as IEC/EN 62000-3-2 / 4-7. The meter is also equipped with standard USB, RS232 and LAN interfaces for remote control, data logging and data analysis.
