The industry quarter-pak size of 2.3" x 1.5" x 0.5" coupled with 89% 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 89% efficiency minimizes the requirement for OPTIONS Choice of Remote On/Off logic Configuration Heatsink Available for Extended Operation 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 VSX40 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 VSX40 series.
