California Instruments or Pacific Power agile power supplies. 480VAC 60hz input, variable output. If >250V l-l is needed, add a step-up transformer to the output. Pacific Power 3060MS cabinets can be paralleled to significant output levels. I assembled a lab with about half a megawatt of output power available from a seven cabinet system.
