The ultra-wide output voltage trim range offers major advantages to users who

select the SMT40C series. It is no longer necessary to purchase a variety of

modules in order to cover different output voltages. The output voltage can be

trimmed in a range of 0.9 Vdc to 5.0 Vdc. When the SMT40C series converter

leaves the factory the output has been adjusted to the default voltage of 0.9 V.
