Max input voltage for RNDU2000
Hi there! I'm trying to find some info about max input voltage for RNDU2000 (and not only this one, I assume). I'd like to connect it with a buffer power supply which outputs 13.8V at default. Of c...
Design spec is 12V +/- 5%. On-board DC-DC circuits typically work within +/- 20% range.
BUT: 12V to hard drive is unregulated(except very low voltage drop switch), please check your hard drive 12V rating (typically +/- 10%). So 13.8V is a little over hard drive 12V rating.
Much obliged!
I didn't think of that HDD power supply may not be regulated.
You are right, my WD30EFRX tolerance is 10%. I could just set the output voltage to 13V but I don't want to risk frying both of my HDD's due to some power noise.
I will think it over but I assume that I will end up buying that voltage reduction circuit. It will make things a bit more complicated (like having to use 2x 9Ah batteries instead of one) but it's a safe option.
Thanks a lot both of you!
