I just got my hands on a TI Silent 700 model 707, but it's missing the external power transformer. Unlike similar Silent 700 models, this features an optional battery pack which complicates things beyond my understanding.
Normally I would just look at the back to see how many volts to whack in but it looks like this thing wants AC power, which I haven't seen before at non-mains levels.
Mildly confused I looked into the datasheet to become more confused because this seems to contradict the block diagram which claims 28V:
Lucky for us, the schematics for the thing are available in the maintenance manual in this PDF on page 90 which I have reproduced here:
So, how do I power this thing? Given it accepts battery power, I'm inclined to use a 16V DC source directly into where the battery plugs are (they are readily exposed), but I'm not certain this won't cause any issues. Alternatively, assuming the 20VAC number is correct, I can purchase a mains to 20VAC wall adapter such as the WAU20-2000 from Triad Magnetics.
P.S. Does anybody know what kind of connector this is? I wasn't able to find any reference to it's type in the manual.
EDIT: After more snooping I have confirmed the AC adapter is indeed 20VAC
