The HP 6626A is a four-output DC power supply designed for automated testing and R&D applications requiring precision, isolation, and low noise. Each output operates independently with dual-range capability, delivering 25 W or 50 W per channel. The instrument integrates GPIB control with simple SCPI programming, 14-bit voltage and current resolution, and VXIPlug&Play drivers for rapid system integration. Outputs can be connected in series or parallel to extend voltage or current capacity.
