HP 6675A System DC Power Supply

The HP 6675A is a single-output system DC power supply delivering 2160 W of regulated power for demanding test environments and production applications. This autoranging unIt has 0–120 VDC at 0–18 ADC with low-noise output (1.9 mV RMS, 16 mV peak-to-peak) and tight programming accuracy: voltage to 0.04% + 120 mV and current to 0.1% + 12 mA. Full programmability via front panel or GPIB/SCPI commands enables precise voltage and current control with 35 mV resolution, supported by integrated measurement capabilities and analog control inputs.

The supply incorporates overvoltage and overcurrent protection to safeguard connected devices.
