Isolated (Floating) Output-Option RF

Units can be provided with the output capable of floating up to ±2kV from ground. All controls, programming and monitoring functions are normally referenced to ground. The high voltage output polarity with respect to the floating input terminal is reversible. Floating input connec­tor is Spellman P/N JDK. Mating connector is provided with each unit (Spellman P/N PDB, MHV type UG-932/U). Replace “R” suffix with “RF” for this option.
