The units dual asymmetric output voltages are 5V and 3.3V. The converter features an industry-standard quarter-brick size (2.3" x 1.5" x 0.5") coupled with 90% efficiency. These converters utilize Vx high density technology. This technology has been featured in our highly efficient VKP and VKA series now successfully in use OPTIONS Choice of Remote On/Off logic Configuration Heatsink Available for Extended Operation worldwide. The very high efficiency minimizes the requirement for heatsinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX40C 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 VSX40C series.
