概要（Overview）

The Keysight 6684A is a high-performance DC power supply with a single output and a capacity of 5000W. It offers adjustable voltage from 0 to 40 V and current from 0 to 128 A. Its programming accuracy is 0.04% + 40 mV for voltage and 0.1% + 65 mA for current at 25 ± 5°C. The device ensures low ripple and noise with voltage rms at 1.0 mV and peak-to-peak at 10 mV, in the frequency range from 20 Hz to 20 MHz. Designed for test optimization, it features selectable compensation for inductive loads, analog control of output voltage and current, and controlled fan speed for reduced acoustic noise. The 5120W, GPIB-compatible 6684A model is known for its stability, reliability, and integration ease in manufacturing tests, along with extensive protection features.
