Hi!
I have 6 DTP 16HC-1 sets(cordless) and no power wall adapters.
I know the V in and the polarity, but I don't know what the current rating is on the wall adapter.
Anyone have one of these handy to look at and see waht the current rating is, or perhaps a NEC part # off the wall adapter?
Thanks in advance!

i can look tomorrow

I have found that these work w/out the ACA adapter, try connecting to a digital station port & see what happens. You should get the little charge light by the handset.

Thanks, Chrislebeck and DrPBX.
I have to ship these out to customers on site, so they have to be complete with the AC adapters, otherwise the digital port idea would work for me, Doc.
Chris, thanks for taking the time to look!

ACA-U, ac power adapter PN-770310.
Hope this helps.

Doc, that's awesome, just the ticket!
Thanks! Chrislebeck, Thanks to you too!

as a future reference:

they also have a ac-r part number 780109

in 120vac
out 27vdc @ 750ma

center is -
outside is +

the only difference i think is the connector is at 90 degrees
