This Digital Interface system uses a proprietary bus structure to provide a very low noise, highly stable control for up to 64 of our Precision High Voltage power supply modules, both unipolar, and reversible, via a single USB port.
A simple ribbon cable connection scheme to a master interface and a 24V power supply enables a safe, flexible, multichannel high voltage system to be quickly and easily configured, and reconfigured, for such applications as Mass Spectrometers, Electron Microscopes, & Surface Science Equipment.
A fibre-optic data path is also available for high voltage isolation, for Electron Gun and Ion Gun applications, where control of a group of power supplies elevated to many kV is easily configured.
Safety is paramount: power is removed from a module, the moment its comms path is broken. |
