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 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:
ST60P24
This would be an ST with a 60kV, positive polarity, providing 24kW’s of power (2 chassis)

Arc Intervention
Spellman’s ST power supplies have an arc intervention feature that senses arc currents via a fast acting current sense transformer. The purpose of the arc intervention circuitry is to prevent power supply damage from continuous, long term arcing. The factory default configuration will trip off the unit with an Arc Fault if 4 arcs occur in a 10 second time period. Customers can change basic arc intervention parameters (Arc Count, Arc Quench, Reramp Time, and Window Time) within preset limits via the digital interface; customized units can be provided for unique arc prone environments, contact Spellman for details.

Electronic Component (Power Source)
ST series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The ST series is not intended to be operated by end users as a stand-alone device. The ST series power supply can only be fully assessed when installed within a system, and as a component part within that system.

*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 units are limited to a maximum output of 10kW’s
NOTE: ST225 units cannot be paralled!
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.
