The SVA is ideally suited for accepting a standard 4 – 20mA DC control signal and providing a higher (e.g. 20 – 160 mA DC) output, which will directly drive actuators used in Turbine, Speed Governor, and Vari-axial Fan control actuators.

The SVA is utilized to drive valve positioners/actuators utilized in some hydraulic equipment which require a 0 – 200 mA DC signal conversion from a standard DC signal level.
