Description
The Agilent 6681A model is part of the 6680 series of power supplies have been designed to provide performance needed for critical applications. These switching power supplies can be used in many noise sensitive applications where linear supplies were once the only solution. The low noise has been achieved while still preserving the efficiency and compactness of a switching supply. The 6680 series also provides a variety of protection features for both the load and the power supply.
Reliable dc power for manufacturing test and long-term burn-in This series of 5000 watt dc power supplies 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 VXIPlug&Play drivers. The output voltage and current can also be controlled with analog signals. This is helpful for certain types of noisy environments, and also immediate reactions to process changes.
The 6681A Series 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.
