MEASUREMENT AND CALIBRATION INSTRUMENTS High Voltage DC Power Supplies

Spellman's 12 kW ST high-voltage power supplies are available in positive or negative polarity in 20 different models with outputs in the range of 1 kV to 225 kV. A full-featured front panel allows easy local control, while a full analog interface provides extensive remote functions. Standard Ethernet and RS-232 digital interfaces simplify the integration of the ST series into your system design.

The robust ST series IGBT inverter is inherently fault tolerant and ideal for demanding applications such as semiconductor processing and vacuum deposition. The user can configure many operating features to suit their particular requirements. More than 100 kW of power can be provided by setting up an additional chassis in parallel.

Typical applications:

    Ion Ray Implantation
    Semiconductor processing
    Electron beam welding
    Capacitor charging
    High Power RF Transmitters
    Electrostatic precipitators
    X-ray systems

Digital Interface 

The ST features a standard RS-232 and Ethernet digital interface. Utilizing these standard digital interfaces can dramatically simplify power supply interfacing require­ments saving the user both time and money, while enhan­cing functionality and overall capability. Spellman pro­vides a GUI with the ST that allows the customer to both customize operational features of the ST while also pro­viding basic power supply operational features. Details of the ST’s digital interface capability are described in detail in the ST manual, downloadable via the link on the first page of this data sheet.
