The Keysight E3643A is a 50 W single-output, dual-range programmable DC power supply engineered for R&D, design verification, and production test environments. It delivers clean, stable power across two selectable ranges: 0–35 Vdc at 0–1.4 A, or 0–60 Vdc at 0–0.8 A. Programming accuracy reaches ±(0.05% + 10 mV) for voltage and ±(0.2% + 10 mA) for current. Line and load regulation both measure 0.01%, while output ripple remains below 8 mV peak-to-peak and 1 mVrms in the normal mode. Transient response recovers in under 50 µs following half/full load transitions, with voltage settling within 90 ms across any load condition.
