You can find a sample here: http://tinyurl.com/648p67 These are 600A 1200V modules. They are way overengineered for the application which is going to be 144V with a max amperage of 350-400A in short pulses. Ebay folks seem to have a ton of them available for a reasonable price. Enough to purchase a couple of hot spares if necessary. BAJ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
