The HP/Agilent 6269B is a 2000 W DC power supply delivering 0–40 V and 0–50 A output with excellent regulation, low ripple (25 mA RMS), and fast transient recovery (≤50 μs). It operates in constant voltage and constant current modes with automatic crossover, dual coarse/fine controls, large analog panel meters, and adjustable overvoltage protection with crowbar circuitry. The supply supports analog programming (voltage, current, or both via options 020, 021, 022), remote sensing, and multi-unit configurations—series, parallel, or tracking operation for up to three units. Auto-ranging thermal management and rear-panel connectivity enable flexible system integration. Input power is 208 VAC, 18 A standard (230 VAC available); optional 50 Hz, single-phase, and alternative voltage inputs are selectable. Full-rack width package, approximately 89 lbs net, ships without line cord.

– Compatibility & Integration
Auto-series, auto-parallel, and auto-tracking modes simplify multi-supply setups. Rear-panel terminals support AC input, remote voltage sensing, and analog control/programming connections. Optional modules (020, 021, 022) enable external voltage and current programming. Alternative AC input frequencies and voltages (options 005, 027, 028) accommodate different power infrastructure.
