Datasheet Accessory Kit

This Single-Output, 5000 W, GPIB Keysight 6681A dc power suppy has the exceptional, proven reliability that test system engineers look for. It also has the features needed for easy test system integration.

Programming of the DC output and the extensive protection features can be done either from the front panel or using industry standard SCPI commands, via the GPIB. Using the serial link, up to 16 power supplies can be connected through one GPIB address. Test system integration can be further simplified by using the VXI Plug&Play drivers. The output voltage and currentcan also be controlled with analog signals. This is helpful for certain types of noisy environments, and also immediate reactions to process changes.

The Keysight 6681A DC Power Supply has extremely low ripple and noise for a 5000 watt dc power supply. This helps the built-in measurement system make extremely accurate current and voltage measurements. Selectable compensation is provided for problem-free powering of inductive loads.
