12kW High Voltage Power Supplies
Spellman’s ST Series of 12kW high voltage power supplies are available in positive or negative polarities in 20 different models with outputs ranging from 1kV to 225kV. A full featured front panel allows easy local control, while an extensive analog interface provides comprehensive remote capability. The standard Ethernet and RS-232 digital interfaces simplify integrating the ST into your system design.
The ST’s robust IGBT inverter is inherently fault tolerant and is ideal for demanding applications like semiconductor processing and vacuum deposition. Many operational features can be configured by the user to suit their particular requirements. Power >100kW’s can be provided by configuring additional chassis in parallel.
Parallel Capability
The ST series is designed to offer additional power capability by adding a chassis in parallel to create a main/secondary configuration providing up to and beyond 100kW’s. The main chassis is the point of connection for customer interfacing; this multichassis system effectively functions as a single power supply. The main unit retains the full featured front panel, while secondary units have a Blank Front Panel. To configure an orderable model number, simply use Spellman’s applicable base ST model number and increment the power denominator in 12kW steps as required.
as required.
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.
Parallel operation
Additional power can be provided in increments of 12kW’s by connecting chassis in parallel via the use of the ST’s main/secondary configuration.
Use the applicable base ST model number and increment the power denominated in 12kW steps as required.

*Substitute “P” for positive polarity and “N” for negative polarity. Polarity must be specified at time of order. 1-10kV units are inherently reversible by design requiring an internal wiring change to swap polarities. Intermediate voltage units are available by special order. 150kV and 225kV units are limited to a maximum output of 10kW’s
NOTE: ST225 units cannot be paralled!
