ARC/Short Circuit Are your supplies current protected? Why is the short circuit repetition rate of my load set-up important? What is the difference between instantaneous short circuit current and continuous short circuit current? Interfacing What kind of high voltage connector do you use on your supplies? Can I program your supplies with a computer? Safety What is a safe level of high voltage? Where can I obtain information on high voltage safety practices? What is an "external interlock"? Why should I use it? Technology/Terminology What is the difference between a modular supply and a rack supply? What is the difference between voltage mode and current mode? What is power control? When would it be used? What is floating ground? What is solid encapsulation? Why is oil insulation used? What is corona? What is a resonant inverter? What is a voltage multiplier? Usage/Application Positive polarity, negative polarity, reversible polarity; why is this important when I purchase a supply? Can I run your supplies at maximum voltage? Maximum current? How much should I de-rate your supplies? Can I get twice the current from your supply if I run it at half voltage? Why is the fall time of your supplies load dependent? How should I ground your supply? Can I float your supplies?
