The HP/Agilent 6680A is a 5000 W single-output system power supply engineered for high-current, precision voltage delivery in demanding test and burn-in applications. It delivers 0–5 V at up to 875 A with exceptional output stability: 1.5 mV RMS ripple and 10 mV peak-to-peak noise in constant voltage mode. Programming accuracy reaches 0.04% + 5 mV for voltage and 0.1% + 450 mA for current, supported by load and line regulation of 0.05% + 7.5 mV. Transient response recovers within 150 mV in less than 900 μs following full-range load steps. The unit accepts three-phase AC input at 180–235 Vac or 360–440 Vac (47–63 Hz) with optional configurations, drawing 7350 VA and 6000 W input power.
