The Philips PM2811 is a single-output programmable DC power supply delivering 0–30 V at 0–10 A (60 W) for precision bench-top and automated test applications. Built with GPIB/SCPI control, the PM2811 combines high output accuracy (±0.04% + 10 mV voltage; ±0.1% + 50 mA current) with fast programming response and comprehensive protection. Its autoranging architecture and internal memory support flexible voltage/current configurations within rated power limits.
