Programmable AC Loads
Chroma 63800 Series
Chroma 63800 programmable AC electronic loads simulate a wide range of real-world load profiles, including high crest factor, varying power factor, rectified, and inrush-current conditions. Real-time compensation maintains accurate loading even when the input voltage waveform is distorted, helping prevent unintended overstress and producing consistent, unbiased test results.
Available operating modes support comprehensive testing of conventional and nonlinear power devices. Engineers can program load conditions, capture measurements, automate test sequences, and reproduce operating scenarios that are difficult to achieve with fixed resistive load banks.
- 63802 Programmable AC Load 1800W / 18A / 350V
- 63803 Programmable AC Load 3600W / 36A / 350V
- 63804 Programmable AC Load 4500W / 45A / 350V
Regenerative AC Loads
Chroma 63800R Series
For higher-power applications, Chroma regenerative AC electronic loads return absorbed energy to the facility instead of dissipating it primarily as heat. This reduces power consumption, cooling requirements, and operating costs during extended-duration or repetitive testing.
The Chroma 63800R Series provides power ratings from 9 kVA to 15 kVA in a compact, high-density platform. Multiple units can be operated in parallel for applications requiring greater load capacity, making the system suitable for development, validation, qualification, and production testing.
Regenerative AC loads are especially valuable for continuous testing of high-power equipment where energy efficiency, laboratory heat management, and system scalability are important.
