APPLICATIONS
Distributed Power Architectures Workstations EDP Equipment Telecommunications
The VSX60 Series are dual output converters with 18-36V and 36-75V input models with 3.3Vdc and 5Vdc outputs. The industry quarter-pak size of 2.3" x 1.5" x 0.5" coupled with 90% efficiency is an industry high-density breakthrough. These converters utilize Vx high density technology. This technology has been featured in our highly efficient VKP and VKA series now successfully in use worldwide. The very high 90%
OPTIONS
Choice of Remote On/Off Logic Configuration Heatsink Available for Extended Operation
efficiency minimizes the requirement for heat-sinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX60 series feature virtually all of the options required by design engineers but not at the competition's typical additional price for each option. This multitude of features are standard on the VSX60 series.
