Can I float your high voltage power supplies?

Spellman's standard products are for the most part, designed and intended for use as ground referenced power supplies. That is, only one high voltage output connection is provided, while the current return path is made via the customer-provided ground referenced load return wiring. This load return must be connected to a reliable earth ground connection for proper operation and transient protection.

Many applications do exist, like ion beam implantation, which require supplies to operate at reference voltages other than earth ground. A supply of this nature is said to "float" at some other reference potential. If your application requires a floating power supply, please contact our Sales Department to review your requirement.
