Chroma 63802 AC/DC Electronic Load

Overview

The Chroma 63802 is a programmable AC/DC electronic load designed for testing power supplies, inverters, and other electronic equipment under various operating conditions. Using state-of-the-art DSP technology, it simulates a wide range of load conditions including non-linear rectified loads with high crest factors and varying power factors. The load provides real-time compensation to accurately simulate real-world scenarios even with distorted voltage waveforms, preventing overstressing of the device under test and ensuring reliable, unbiased results.
