Agilent/Keysight 6671A DC Power Supply

The Agilent/Keysight 6671A is a 2000 W DC power supply engineered for high-current applications requiring precision voltage and current regulation. Single output delivers 0 to 8 Vdc at 0 to 220 A, with programmable constant voltage (CV) and constant current (CC) operation modes. GPIB interface enables remote control and integration into automated test systems. The unit combines tight load regulation, low ripple performance, and comprehensive protection—including programmable overvoltage, overcurrent, and over-temperature safeguards—making it suitable for demanding industrial and laboratory environments.

– Technical Specifications

Output voltage ranges from 0 to 8 Vdc with output current from 0 to 220 A, delivering 1760 W actual output power. Programming accuracy (at 25°C ±5°C) specifies voltage to 0.04% + 8 mV and current to 0.1% + 125 mA. Load regulation holds voltage to 0.002% + 300 µV and current to 0.005% + 10 mA. Ripple and noise performance (20 Hz to 20 MHz) measures 650 µV rms and 7 mV peak-to-peak for voltage; current ripple reaches 200 mA rms. Readback accuracy (at 25°C ±5°C) provides voltage measurement to 0.05% + 12 mV and current to 0.1% + 150 mA. AC input operates from 191 to 250 Vac, 47–63 Hz.
