Derek, As long as you are not looking for a programmable supply that will do the actual transients for you, I would go with an unregulated stiff supply, so that when you inject transients and ripple, the supply doesn't fight you. Make sure ripple is low enough you don't need to provide external filtering, those filters can hurt you at voice frequencies which are in band to power quality transient spectral content. You want to be able to vary the dc output over the entire range of -704/DO-160 steady state levels. Such variation might be obtained with an auto transformer on the unregulated power supply's ac input if not available internally.

Does anyone have opinions on what would make a good choice? I believe a current draw up to 25 amps would cover most things I need to do. Thoughts on and off-line are welcome. -- Cheers, Derek Walton L F Research Poplar Grove, IL 61065, USA - --------- ------------------------------------------------------ This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
