The Cerus X-Drive is a variable frequency drive that offers an extensive range of amperage and configuration options, making it versatile enough for nearly any constant or variable torque application. Industry standard application settings are pre-configured for submersible or centrifugal pumps, supply or exhaust fans, cooling towers, vacuum pumps, and constant torque and permanent magnet motors. In addition, many input/output and control options are available for application specific features,
such as PID speed control, pressure control, temperature or level controls.
