4600 Series AC Load

Source: NH Research
4600 Series AC Electronic Loads are intended for applications that require the entire range of non-linear loading
  • Programmable power-factor & crest-factor
  • 3KW/30A and 6KW/60A power ratings
  • Built-in, high-accuracy measurements
  • Graphical user interface and LabVIEWtm driver

    • 4600 Series AC Electronic Loads are intended for applications that require the entire range of non-linear loading to thoroughly test AC-output power conversion products such as uninterruptible power supplies (UPS) and inverters. The benefits of such a wide range of loading control is to assure product performance under every possible "real world" operating condition.

    Non-Linear Loading
    The advantage of testing with a programmable, non-linear (i.e., any power-factor and crest-factor) load are substantial. The most significant being the ability to rapidly test products at every possible loading condition that could ever be encountered in the field. The other major benefit is the ability to instantly switch over to a different set of loading conditions as product needs dictate. With such versatility, a higher level of product quality is assured and manufacturing test throughput is increased.

    Broad Operating Envelope
    To cover the most common UPSs and inverters, the 4600 Series is offered in two power ranges, 3000W and 6000W. Higher power levels can be acheived by utilizing additional units in parallel. All units operate from 50 to 350VAC and in several emulation modes such as Constant-Current, Voltage, Resistance, Power as well as Short-Circuit.

    A "One Box" Test Solution
    With a PC controller, everything needed to test most AC-output products is contained within the 4600 Series instruments. In addition to the flexible load control, twelve high-accuracy measurements include voltage, current, peak-current, frequency, crest-factor, power-factor, and true power. Even the real-time voltage, current and power waveforms are displayed on the PC soft-panel. This ability to make all measurements internally eliminates multiple, external measurement instruments plus associated signal matrixing and interconnect wiring. In this manner the 4600 Series provides for a more compact, less costly and considerably faster test solution.
