HP / Agilent 6622A System Power Supply, 80W, 2 outputs

The HP/Agilent 6622A is an 80 W dual-output DC power supply engineered for automated test equipment and benchtop system integration. It delivers two independently controlled, isolated outputs with dual-range capability—0 to 20 V at 0 to 4 A, or 0 to 50 V at 0 to 2 A per channel. The unit supports SCPI programming via GPIB with VXIplug&play drivers, enabling rapid test system deployment. An active down-programmer sinks full rated current during fast voltage descent, minimizing test cycle time. Voltage ripple measures 500 µV RMS with 3 mV peak-to-peak noise across 20 Hz to 20 MHz. Programming accuracy reaches 0.06% + 50 mV for voltage and 0.16% + 40 mA for current. Load regulation holds voltage to 0.5 mV, while cross-regulation between outputs maintains 0.25 mV. Programmable over-voltage and over-current protection safeguard connected devices. Remote sensing compensates up to 1 V drop per load lead. The 3U form factor measures 425.5 mm × 132.6 mm × 497.8 mm and weighs 17.4 kg. Peak input power consumption is 550 W at 720 VA maximum.
