HP 6681A System Power Supply

The HP 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 HP 6680 series also provides a variety of protection features for both the load and the power supply.
