Keysight / Agilent / HP 6622A 80 W High Voltage Dual Output Linear DC Power Supply

The Keysight/Agilent/HP 6622A is an 80 W dual-output linear DC power supply engineered for precision measurement and test applications requiring low-noise, independently isolated outputs. Each output operates across dual voltage and current ranges—0 to 20 V at 0 to 4 A, or 0 to 50 V at 0 to 2 A—with automatic range selection and the ability to connect outputs in series or parallel for extended capabilities. The instrument delivers voltage ripple of 500 µV rms (3 mV peak-to-peak) and current ripple of 1 mA rms across the 20 Hz to 20 MHz bandwidth, making it suitable for sensitive analog circuits and precision component testing.
