This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
How it works
The power supply converts the single-phase AC mains supply into a three-phase, low-voltage, medium-frequency output to power the turbomolecular pump. A single-chip microcomputer generates the variable output frequency and controls the three-phase output voltage based on software and gas load conditions. The controller's internal components include a power transformer, a front panel with an LCD alphanumeric display and keyboard, a rear panel with input/output connectors, and printed circuit boards containing the power supply and three-phase output section, analog and input/output section, microprocessor and digital section, and display and keyboard circuits.[2]
Operation can be conducted via front-panel switches, remote signals through rear-panel connectors, or an RS-232, RS-485, or RS-422 serial link. The controller provides remote start/stop, pump status signals, forepump start/stop, and interlock control for external devices such as pressure switches or water flow switches. An internal EEPROM stores pump operating parameters and programmed input/output information.[2]
