Digital Interface

The STA 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 STA that allows the customer to both cus­tomize operational features of the STA while also providing basic power supply operational features. Details of the STA’s digital interface capability are described in the STA manual, downloadable via the link on the first page of this data sheet.

Arc Intervention

Spellman’s STA 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.
