6620A Series Multiple-Output,
40-105 W DC Power Supplies, GPIB
Speed and accuracy for test optimization
– Up to four fully isolated power supplies
in a 3U package
– Dual-range outputs
– Fast, low-noise outputs
– Built-in measurements and advanced
programmable features
– Protection features to ensure DUT safety
Data Sheet
Two, three, or four isolated outputs are integrated into one package, conserving rack space
and GPIB addresses. Most of the outputs also provide dual ranges, for more current at
lower voltage levels. The outputs can be connected in parallel or series to further increase
the flexibility that these products offer the system designer.
Programming is done using industry standard SCPI commands. Test system integration can
be further simplified by using the VXIplug&play drivers. These power supplies help reduce
test time with fast up and down programming, enhanced by an active downprogrammer which
can sink the full rated current.
