The Keysight E3634A is a 200 W single-output, dual-range programmable DC power supply engineered for benchtop and system-level test applications. Its dual voltage/current ranges—0 to 25 VDC at 0 to 7 A, or 0 to 50 VDC at 0 to 4 A—deliver flexibility for diverse load requirements. Programming accuracy of ±(0.05% + 10 mV) on voltage and ±(0.2% + 10 mA) on current, combined with load and line regulation better than 0.01% + 250 µA, ensures stable, repeatable power delivery for R&D, production testing, and quality assurance workflows.
