These products are often tested with resistive load banks, but this approach does not simulate real-world conditions such as switching DC/AC converters found in many AC powered products.
As a result, using resistive load banks does not fully exercise the equipment under test (EUT) under worst case operating conditions. High peak currents and low power factor loads can significantly impact the operating characteristics of a UPS or AC power product.
A better way to test these products is with an AC electronic load, such as the California Instruments 3091LD AC eLoad. An AC electronic load can simulate high crest factor and variable power factor load conditions in addition to providing a purely resistive load, effectively simulating real-world conditions and significantly increasing product reliability. Product defects that result in costly field returns are detected well before a unit reaches a customer site.
An AC electronic load should have the following modes:
