- N69200 series is a high performance high power programmable DC electronic load with high reliability, high precision and multi-function. N69200 series has three voltage specifications: 150V, 600V, and 1200V. A standard 19”3U chassis can be up to 6kW. It supports parallel control and can realize power expansion through master+master and master+slave. N69200 supports three ranges of voltage, current, power and resistance, and provides high-precision measurement, which makes the test range wider of a single unit.
