Author Topic: OBi1032 PSU rating?  (Read 3549 times)

My OBi1032 phone was supplied without a PSU and I've been using the one from my spare OBi110.  The phone wasn't working today and I found the PSU was giving zero volts.  No problem to repair - the Schottky rectifier was a short circuit.

However my question is what current rating is marked on the PSU that Obihai supplies with the OBi1000 series phones?  The underside of the phone does have 12v DC as part of the case moulding but no indication of current required.  (The PSU for the OBi110 is marked 800 mA.)

They are the same power supplies as are used with all of the OBi ATAs.

Thanks.  I expected that they are all the same.  Seems mine was just a random failure and not brought about by overloading.

Yah, the only difference I've seen is in the length of the DC cord (too short on the early-shipped 1000 series), and that some have a straight plug and others have a 90-degree angle plug.

BTW, you can also use an Ethernet PoE injector, if the desired location of the phone isn't near an AC outlet.
