The Agilent Varian V550 rack-mount controllers can power the Turbo-V 551 turbo molecular pumps, its cooling fan, and its vent valve. These Agilent Varian V550 rack-mount turbo pump controllers can operate on 100, 120, 220, or 240 volts AC input power. A manually operated input voltage selector is integrated into the rack mount controller power supply input (see photo below). A flat-head screwdriver can be used to pop out the voltage selector box, rotate the voltage selector to the desired input voltage, and re-insert. The Agilent Varian V550 Navigator rack-mount turbo pump controllers also incorporate auxiliary power connectors (1 Amp max output) for powering the cooling fan and vent valve devices. These auxiliary connectors are located in the upper right-hand corner on back side of controller (see figure below).
