The Keysight E3648A is a 100 W dual-output, dual-range programmable DC power supply engineered for R&D, production, and quality assurance environments. It delivers precise, low-noise power across two independent channels with selectable voltage ranges: 0–8 V at 0–5 A, or 0–20 V at 0–2.5 A per output. Load and line regulation of ±0.01% of output plus offset ensures stable operation for sensitive analog and digital circuits.
